First, atmospheric stunning Hisense EC760UC depth evaluation report
Since LG and Samsung launched the curved TV prototype at CES2013, LG first surface TV was introduced. Samsung also closely followed the launch of the 55-inch curved TV. Afterwards, many manufacturers have stepped in this Red Sea area. It seems that many people will say that only foreign-funded companies can produce curved-surface TVs. This is not the case. Since last year, Hisense, TCL and other domestic brands have also shown their own "killer" - curved TV.
We can't help but wonder if flat-panel TVs have completely replaced spherical TVs in the past 10 years. Will the emergence of curved TVs produce similar substitution effects? To figure out this problem, first of all, what is a curved surface? TV.
As the name suggests, the curved TV is a screen with a certain curvature, has a certain surface shape, the curvature of the general surface TV and the curvature of the eyeball is basically the same.
The curved TV has three improvements in comparison with the flat TV:
1. A wider angle of view: Compared with flat-panel TVs of the same size, curved TVs give people a greater sense of vision and a wider field of view. The curved surface structure is more compatible with the curvature of the eyeball, accepting more abundant image information, and viewing more comfortable. natural.
2. More immersive on the spot: Immersive experience is the biggest selling point for curved TVs. Similar to the IMAX screen of a movie theater, a slightly curved screen can provide a deeper wrap-around viewing experience.
3. Contrast is better: In actual tests it can be found that curved TVs usually have better contrast than flat TVs. For example, Samsung added a contrast adjustment mechanism for “depth†in image processing, not only for 3D images, but also to enhance the viewing effect of 2D images, allowing the screen to have a deeper sense of depth.
Hisense series LED55EC760UC smart TV enhances the video effect through HDR, surface and other technologies, and enhances the audio effect through the pre-sounding independent tone Bar, providing multiple extreme experiences of presence, color, and sound. It is no exaggeration to say that the LED55EC760UC smart TV is by far the most competitive curved TV!

The variety show as the mainstream today, LED55EC760UC smart TV not only has domestic hot programs, but also shielded keywords and shielded keywords and other foreign popular programs to meet the trend of national entertainment.
Variety channels cover freshly baked programs. Not only are there domestic hotspots, but overseas popular programs are also included.
Education is an eternal topic. The polyhedron in LED55EC760UC smart TV covers a wealth of video resources, and more than 10,000 hours of genuine mass education video library, and continues to increase. From infants, elementary schools, junior high schools, high schools, arts, and vocational education, there are not only many free resources, but also excellent quality. Most of them are in the form of illustrations and texts. They can also effectively supplement knowledge at home. It seems that Hisense did not Only taking into account the feelings of adults, even children's needs are fully taken into account, bringing a perfect big-screen education experience.
The focus is on, if you just buy back to watch digital TV and online video, traditional TV can also do it. The significance of smart TV lies in its powerful expansion capability, which is what we often call APP. LED55EC760UC smart TV has a wealth of resources available for download in the "Cool Application" category. Of course, third-party APPs can be installed and compatible with most Android APPs.

Found that WiFi transmission Larger videos are still smooth and there is no chance of getting stuck.
Fourth, hardware articles: the king of deserved performance
In addition to smart LED55EC760UC smart TV, 4K is also a very attractive selling point.
Here to briefly talk about the LED55EC760UC smart TV hardware parameters, 4-core Cortex A53 CPU, clocked at 1.2GHz, 6-core Mali 450 GPU and 4-core NEON coprocessor, 1.5GB RAM and 8GB ROM combination, easily face 4K video And large games ensure smooth and comfortable experience. The new 2K to 4K correlation compensation technology, through real-time analysis of 2K signals, divides the signal into 2 million two-dimensional intervals, and the 2K signal is raised to 4K signals, and the image reduction rate is also increased by 90%.
Early curved TVs were bent for bending, and simple physical bending led to screen leakage, distortion and even color unevenness, which greatly affected the viewing effect. With the development of technology, the curvature of the screen is gradually upgraded. It is generally believed that when the curvature is less than 3000R, the human eye will feel uncomfortable while watching, and 4000R is considered as the golden curvature viewed by the human eye.
In fact, it is not just a curved screen. The birth of a widescreen is also to get closer to the human eye. Only the widescreen is not only in line with the human visual effects, but is also low in the panel cutting cost. Therefore, the popularization speed is very fast, while the curved screen TV's visual impact is not particularly large, but the cost increase is more obvious, so the general Only the high-end flagship can see the curved surface TV. Of course, it's true that curved surface televisions exist for pursuing the ultimate viewing experience.
After a large amount of data verification, the 4000R golden curvature screen can give the user three viewing advantages:
First, to provide a golden arc, the arc is closer to the human eye, so it can effectively reduce the user's visual fatigue;
Second, to provide a golden perspective, the distance from each detail of the screen to the eye is equal, there is no deviation, the screen has no color cast, and more brilliant details can be captured than ordinary screens, and the perspective is wider;
Third, to provide a golden perspective, the 4000R golden curvature screen has a depth of more than 47mm, and even in 2D images, 3D effects can be experienced.
With 4K resolution of 3840x2160 and a pixel value of up to 8.3 million, it delivers crisp, clear resolution. 2K to 4K correlation compensation technology to improve the frequency multiplier screen, with the curved screen, a clear picture of each frame, allowing users to capture every wonderful detail, more easily immersed in the picture depicted in the scene.
The new 2K to 4K correlation compensation technology divides the signal into 2 million two-dimensional intervals through real-time analysis of 2K signals. The adjacent interval performs four-dimension color operation in horizontal and vertical directions, achieving 90% image realism. Above, it effectively compensates for the shortage of 4K sources.
From 1080P to 4K, although the improvement of the resolution brings a more refined picture, the overall effect does not have an imaginative leap. The upgrade of the regional control light and image engine is also lackluster. In fact, regardless of what the manufacturers bragged about, picture quality is still a topic to avoid.
The two important factors in measuring image quality are contrast and color accuracy. If two TVs are put together for comparison, one of them has better contrast and color accuracy, and the other has higher resolution. Then almost Everyone will think that the former's picture quality is better. Although the resolution is lower, higher contrast and color accuracy will make the picture look more realistic and natural. Therefore, the only technology that can really improve the picture quality seems to be HDR and quantum dots.
Then the question is, what is the HDR of IFA2015? Why is this technology sought after by so many vendors?
The concept of HDR TV appears to be a bit later than Quantum TV, leading to consumer perceptions of HDR and its quantum dots are still unfamiliar.
HDR stands for High-Dynamic Range. HDR is not a new word. When taking pictures, because the camera's dynamic range (degree of latitude) is limited, when the scene contains both bright and dark contrasting scenes, such as the sky and the ground, the camera can only measure the exposure of one of the scenes. The result is The picture obtained is either overexposed or too dark.
The camera HDR will quickly take multiple photos with different exposure values ​​and combine them into one. Compared to ordinary images, HDR images can provide more dynamic range and image details. According to LDR (Low-Dynami Range) images with different exposure times, LDR images corresponding to the best detail for each exposure time are used to synthesize the final HDR. image. It not only retains the lightness of the brightness, but also reveals the darkness of the details. The contrast is high, the brightness is clear, and the colors are vivid. This maximizes the look and feel of the photo when it is photographed.
And this time we have to say that television HDR and camera HDR have common places, but they are not the same. Strictly speaking, camera HDR is not really high dynamic range, nor can it really achieve HDR. The HDR dynamic range of the photos has not actually changed, but the additional exposure has brought additional information.
TV HDR is a completely different technology, the difference in the way it changes the picture. This is based on the principle of the LCD. The LCD needs the backlight to present the content, and the LCD responsible for the brightness adjustment cannot cover the light by 100% (Of course, if the light is blocked, we cannot see the image). So when the black scene is displayed, there will still be some light leakage, making the black impure, which is also what we often say light leakage.
This restriction causes LCDs to fail to match OLEDs in contrast and color gamut, and HDR happens to improve on these two issues. Then the question is, how does HDR achieve LCD high dynamic range?
The original manufacturer wanted to achieve high dynamic range of the LCD. It is not difficult to say that it is difficult. Since the LCD can not cover 100% of the light, it can be directly turned off. This is also the origin of the regional light control. However, each pixel of the LCD is not an independent light source like the OLED, and one backlight covers all the pixel backlights of one area.
Area control is the ability to automatically identify black areas in the image, turn off or reduce the brightness of this part of the backlight to achieve true black and enhance the contrast of the picture.
The most important aspect of TV HDR is to increase the brightness from 400 nits to 1,000 nits, or even higher. The increase in brightness can make the picture more real, especially in outdoor scenes.
While TV HDR dramatically improves the contrast and color accuracy, the bright part of the picture will be clearer, the dark part will be more in depth, and the look will be clearly structured. The increase in color accuracy will make the colors look more pure and bright. As a result, a more pure display effect, a richer warm and cold alternation, and a wider range of colors are achieved.
In addition, WCG (Wide Color Gamut) will also come along with HDR, which will greatly expand the color that TV presents, and thus present a more realistic effect. At the same time, TV HDR does not look the same as HDR in photos but only enhances the picture quality.
In order to test, I put the mobile hard disk with 4K video into the LED55EC760UC smart TV and switch to the USB signal source. It can be seen that although the video format is various, the LED55EC760UC smart TV still recognizes the copied video.
First 1080P video playback, LED55EC760UC smart TV is simply no pressure, dynamic contrast and details of expression are very good, no dragging progress bar Caton, with excellent sound effects, really have the feeling of immersive.
The grayscale effect is also very good, the transition is soft and natural, there is no stiff cutting sense, the brightness of the various levels can be divided with the eyes.
The pre-sounding independent tone Bar brings outstanding stereo sound effects and effectively avoids the space limitations of an independent external audio system. At the same time, Hi-sound professional audio solutions can be used to bring a wider audio range. Direction has a rich listening experience. The treble is bright, the bass is full, the midrange is full, and Dolby and DTS+Trusurround HD decoding capabilities are perfectly supported, so I'm still looking forward to the audio part.
The author listened to Li Jian's "Wind-worn Wheat Waves." From 1 second to 10 seconds, the sound was from far and near, as if passing from one place to another, with a sense of presence; between 10 seconds and 36 seconds, the stereo effect was very good. Obviously, the sense of penetration of high notes and the sense of distance are the same.
Summary: The combination of top curved screen and ultra-narrow metal frame makes the LED55EC760UC smart TV gorgeous and elegant, 4000R gold curvature, 4K RGB three primary color screens, 0D dimming and HDR, independent tone Bar for front tone design, and exclusive online video service. It's a unique flagship.
Through the actual measurement, LED55EC760UC smart TV, whether it is the fine degree or color performance has reached the industry's high-end standards, especially the introduction of HDR, so that the contrast and color accuracy increased significantly, which means that the screen performance is even more colorful. In terms of picture quality, the effect of 4K resolution enhancement is also very obvious. With 2K to 4K technology, the picture quality of the LED55EC760UC smart TV is truly outstanding. The LED55EC760UC smart TV also really let us experience the sensation of being on the spot. It is a virtual word. Through real listening, we also feel the strong expression of this speaker.
Return to the product itself, LED55EC760UC smart TV worthwhile in the end? The author in-depth experience is that it is worth buying! Hisense on the advantages of content and hardware integration demonstrated in the test, but also innovative and television and mobile phone linkage In addition to pushing programs and remote-control television, it is expected that there will be more chemical reactions between TV and mobile phones in the future, making living room entertainment easier and more fun.
In this LED55EC760UC smart TV to see its pride of nature, proved that "domestic self-improvement" is not just a slogan!
PCB prototype refers to the trial production of Printed Circuit Boards before mass production. After the electronic engineer designs the circuit and completes PCB Layout, the PCB gerber file, etc. is provided to the PCB manufacturer for small batch trial production. The purpose is to verify the correctness of the design and to test individual functions.
After confirming that PCB prototype production and testing are all right, small and medium batch production and mass production can be carried out and electronic products can be put into the market.
Regular factories produce PCB prototypes in order to have batch orders, so of course they want to return orders; PCB prototype manufacturers themselves only do prototypes or small batches, if there is a batch orders generally can not do.
In terms of quality assurance, it is certain that regular factories do better than PCB prototype manufacturing companies. Prototype manufacturing companies are One-Hammer Business. After prototype production is completed, prototype will be sent to you, and then payment will be received. they will not normally carry out flying probe testing. If the quality is not up to you, you have to retake it. Regular factories generally do flying needle testing, from material to process are meticulous and professional, so the quality is often successful once.
A PCB project involves a lot of things, if a product has problems in a certain link, it will easily affect the product development progress; PCB Board making is also the same, generally a project, designed PCB will go to prototype manufacturing, do a few boards for testing, if the test passes, all OK, then you can find batch manufacturers in the future. Direct mass production, the price will be much lower than the prototype manufacturer, prototype manufacturer prototype production is mainly highlighted fast.
Before mass production, we recommend that you use PCB prototype design services for functional testing of new products. The benefits of developing PCB board prototypes include:
If there are any errors, quickly test and correct the design - after waiting more than a week for the board, you will be anxious to get them into your application. You can do this when you pre-test your design with a PCB prototype.
Detection of any early potential design defects-PCB prototype design service allows you to discover any design problems within a few days and correct design errors in time before putting them into production.
Order a small amount of production, MOQ only has five boards if necessary - save money and reduce risk by delaying large orders until you know you have the type of sheet you need.
Benefit from lower production tolerances - It offers a clear indication of how well your PCB will perform
Once the Prototype Board can meet your quality and performance requirements, you can carry out comprehensive production. Then, we will transition from PCB Prototype Board service to standard PCB Manufacturing service, providing stricter production tolerances and more advanced options, including free manufacturing design (DFM) checks, to detect potential problems that may reduce the quality of PCB.
While it may be tempting to simply order your full printed circuit boards and decide you`ll deal with any design flaws that arise as they come, it`s rarely the most efficient solution. You may get the boards out sooner, but if something goes wrong, it could prove to be a lot costlier and more time-consuming than taking an extra few days to test a prototype.
PCB prototyping is a best practice method used worldwide to validate the quality of design before continuing. In the past, some companies might not have time to develop Prototype PCB , waiting for assemblers to put PCB prototypes together and test them. However, due to the rapid prototyping of PCB provided by JHY PCB, this is no longer a problem. You can send your prototype PCB board design Gerber file and production requirements in a week or less, and have a Fast PCB Prototype . It will give you enough time to test the PCB prototype board and prepare for your regular production operation.
Printed Circuit Board (PCB) fabrication is the assembly method for circuit boards used in electronic and computer devices. The layers of the board are put together along with the specific surface pattern so it can be used in electronics manufacturing.
JHYPCB, China PCB Manufacturer offers PCB prototype and fabrication service with 100% quality guarantee, offers 24 hours Quick Turn PCB prototype and Reliable small-batch PCB (Low Volume PCB Prototyping) production, affordable price and best service.
With 8 or more layers of boards - As we are trying to get your board back to you as soon as possible, we provide rapid PCB prototyping for boards with 8 or more layers.
FR-4 board - Your PCB prototype will use standard FR-4 material.
Small and medium batches and mass production - Once you know that your design is effective, you can contact us to obtain standard PCB services for full production in your application.
Slightly longer turnaround time - Since these are the boards you will actually be using, it takes a little longer to make sure we get everything just right. However, now that you have tested the design, you can go right into your projects once you get your boards.
Boards with up to 32 layers - We have much more flexibility with materials and layers once we have the time to develop your full boards.
JHYPCB offers Custom PCB Assembly to go along with our high-quality fabrication and component procurement services in China. This includes fast, affordable PCB assembly Prototype service where we take your unique PCB designs, prepare them for the assembly process and perform comprehensive testing to ensure they meet your precise performance requirements. We can provide a complete turnkey PCB Prototype assembly featuring a one-stop shop approach that saves you time, money and hassles.
Printed Circuit Board (PCB) prototypes are used to reduce the number of errors or defects in the design of a circuit board at an earlier stage. This helps save a lot of costs that otherwise would be spent on rectifying those defects. Thus, most companies prefer to get a prototype PCB assembly servces prior to getting their final design of circuit boards manufactured.

Found that WiFi transmission Larger videos are still smooth and there is no chance of getting stuck.
Fourth, hardware articles: the king of deserved performance
In addition to smart LED55EC760UC smart TV, 4K is also a very attractive selling point.
Here to briefly talk about the LED55EC760UC smart TV hardware parameters, 4-core Cortex A53 CPU, clocked at 1.2GHz, 6-core Mali 450 GPU and 4-core NEON coprocessor, 1.5GB RAM and 8GB ROM combination, easily face 4K video And large games ensure smooth and comfortable experience. The new 2K to 4K correlation compensation technology, through real-time analysis of 2K signals, divides the signal into 2 million two-dimensional intervals, and the 2K signal is raised to 4K signals, and the image reduction rate is also increased by 90%.
Early curved TVs were bent for bending, and simple physical bending led to screen leakage, distortion and even color unevenness, which greatly affected the viewing effect. With the development of technology, the curvature of the screen is gradually upgraded. It is generally believed that when the curvature is less than 3000R, the human eye will feel uncomfortable while watching, and 4000R is considered as the golden curvature viewed by the human eye.
4000R is the golden curvature of the human eye
In fact, it is not just a curved screen. The birth of a widescreen is also to get closer to the human eye. Only the widescreen is not only in line with the human visual effects, but is also low in the panel cutting cost. Therefore, the popularization speed is very fast, while the curved screen TV's visual impact is not particularly large, but the cost increase is more obvious, so the general Only the high-end flagship can see the curved surface TV. Of course, it's true that curved surface televisions exist for pursuing the ultimate viewing experience.
Curved TVs exist for pursuing the ultimate viewing experience
After a large amount of data verification, the 4000R golden curvature screen can give the user three viewing advantages:
First, to provide a golden arc, the arc is closer to the human eye, so it can effectively reduce the user's visual fatigue;
Second, to provide a golden perspective, the distance from each detail of the screen to the eye is equal, there is no deviation, the screen has no color cast, and more brilliant details can be captured than ordinary screens, and the perspective is wider;
Third, to provide a golden perspective, the 4000R golden curvature screen has a depth of more than 47mm, and even in 2D images, 3D effects can be experienced.
With 4K resolution of 3840x2160 and a pixel value of up to 8.3 million, it delivers crisp, clear resolution. 2K to 4K correlation compensation technology to improve the frequency multiplier screen, with the curved screen, a clear picture of each frame, allowing users to capture every wonderful detail, more easily immersed in the picture depicted in the scene.
The new 2K to 4K correlation compensation technology divides the signal into 2 million two-dimensional intervals through real-time analysis of 2K signals. The adjacent interval performs four-dimension color operation in horizontal and vertical directions, achieving 90% image realism. Above, it effectively compensates for the shortage of 4K sources.
From 1080P to 4K, although the improvement of the resolution brings a more refined picture, the overall effect does not have an imaginative leap. The upgrade of the regional control light and image engine is also lackluster. In fact, regardless of what the manufacturers bragged about, picture quality is still a topic to avoid.
The two important factors in measuring image quality are contrast and color accuracy. If two TVs are put together for comparison, one of them has better contrast and color accuracy, and the other has higher resolution. Then almost Everyone will think that the former's picture quality is better. Although the resolution is lower, higher contrast and color accuracy will make the picture look more realistic and natural. Therefore, the only technology that can really improve the picture quality seems to be HDR and quantum dots.
Then the question is, what is the HDR of IFA2015? Why is this technology sought after by so many vendors?
The concept of HDR TV appears to be a bit later than Quantum TV, leading to consumer perceptions of HDR and its quantum dots are still unfamiliar.
HDR stands for High-Dynamic Range. HDR is not a new word. When taking pictures, because the camera's dynamic range (degree of latitude) is limited, when the scene contains both bright and dark contrasting scenes, such as the sky and the ground, the camera can only measure the exposure of one of the scenes. The result is The picture obtained is either overexposed or too dark.
The camera HDR will quickly take multiple photos with different exposure values ​​and combine them into one. Compared to ordinary images, HDR images can provide more dynamic range and image details. According to LDR (Low-Dynami Range) images with different exposure times, LDR images corresponding to the best detail for each exposure time are used to synthesize the final HDR. image. It not only retains the lightness of the brightness, but also reveals the darkness of the details. The contrast is high, the brightness is clear, and the colors are vivid. This maximizes the look and feel of the photo when it is photographed.
HDR photo comparison
And this time we have to say that television HDR and camera HDR have common places, but they are not the same. Strictly speaking, camera HDR is not really high dynamic range, nor can it really achieve HDR. The HDR dynamic range of the photos has not actually changed, but the additional exposure has brought additional information.
TV HDR is a completely different technology, the difference in the way it changes the picture. This is based on the principle of the LCD. The LCD needs the backlight to present the content, and the LCD responsible for the brightness adjustment cannot cover the light by 100% (Of course, if the light is blocked, we cannot see the image). So when the black scene is displayed, there will still be some light leakage, making the black impure, which is also what we often say light leakage.
This restriction causes LCDs to fail to match OLEDs in contrast and color gamut, and HDR happens to improve on these two issues. Then the question is, how does HDR achieve LCD high dynamic range?
The original manufacturer wanted to achieve high dynamic range of the LCD. It is not difficult to say that it is difficult. Since the LCD can not cover 100% of the light, it can be directly turned off. This is also the origin of the regional light control. However, each pixel of the LCD is not an independent light source like the OLED, and one backlight covers all the pixel backlights of one area.
Area control is the ability to automatically identify black areas in the image, turn off or reduce the brightness of this part of the backlight to achieve true black and enhance the contrast of the picture.
The most important aspect of TV HDR is to increase the brightness from 400 nits to 1,000 nits, or even higher. The increase in brightness can make the picture more real, especially in outdoor scenes.
While TV HDR dramatically improves the contrast and color accuracy, the bright part of the picture will be clearer, the dark part will be more in depth, and the look will be clearly structured. The increase in color accuracy will make the colors look more pure and bright. As a result, a more pure display effect, a richer warm and cold alternation, and a wider range of colors are achieved.
In addition, WCG (Wide Color Gamut) will also come along with HDR, which will greatly expand the color that TV presents, and thus present a more realistic effect. At the same time, TV HDR does not look the same as HDR in photos but only enhances the picture quality.
In order to test, I put the mobile hard disk with 4K video into the LED55EC760UC smart TV and switch to the USB signal source. It can be seen that although the video format is various, the LED55EC760UC smart TV still recognizes the copied video.
First 1080P video playback, LED55EC760UC smart TV is simply no pressure, dynamic contrast and details of expression are very good, no dragging progress bar Caton, with excellent sound effects, really have the feeling of immersive.

The grayscale effect is also very good, the transition is soft and natural, there is no stiff cutting sense, the brightness of the various levels can be divided with the eyes.
The pre-sounding independent tone Bar brings outstanding stereo sound effects and effectively avoids the space limitations of an independent external audio system. At the same time, Hi-sound professional audio solutions can be used to bring a wider audio range. Direction has a rich listening experience. The treble is bright, the bass is full, the midrange is full, and Dolby and DTS+Trusurround HD decoding capabilities are perfectly supported, so I'm still looking forward to the audio part.
The author listened to Li Jian's "Wind-worn Wheat Waves." From 1 second to 10 seconds, the sound was from far and near, as if passing from one place to another, with a sense of presence; between 10 seconds and 36 seconds, the stereo effect was very good. Obviously, the sense of penetration of high notes and the sense of distance are the same.
Summary: The combination of top curved screen and ultra-narrow metal frame makes the LED55EC760UC smart TV gorgeous and elegant, 4000R gold curvature, 4K RGB three primary color screens, 0D dimming and HDR, independent tone Bar for front tone design, and exclusive online video service. It's a unique flagship.
Through the actual measurement, LED55EC760UC smart TV, whether it is the fine degree or color performance has reached the industry's high-end standards, especially the introduction of HDR, so that the contrast and color accuracy increased significantly, which means that the screen performance is even more colorful. In terms of picture quality, the effect of 4K resolution enhancement is also very obvious. With 2K to 4K technology, the picture quality of the LED55EC760UC smart TV is truly outstanding. The LED55EC760UC smart TV also really let us experience the sensation of being on the spot. It is a virtual word. Through real listening, we also feel the strong expression of this speaker.

Hisense on the advantages of content and hardware integration demonstrated in the test, but also innovative and television and mobile phone linkage In addition to pushing programs and remote-control television, it is expected that there will be more chemical reactions between TV and mobile phones in the future, making living room entertainment easier and more fun.
In this LED55EC760UC smart TV to see its pride of nature, proved that "domestic self-improvement" is not just a slogan!
Cheap PCB Prototype - Manufacturing And Assembly Services
What is PCB prototype and why it should be used
PCB prototype refers to the trial production of Printed Circuit Boards before mass production. After the electronic engineer designs the circuit and completes PCB Layout, the PCB gerber file, etc. is provided to the PCB manufacturer for small batch trial production. The purpose is to verify the correctness of the design and to test individual functions.
The number of PCB prototypes is usually not specified. It may be one piece, ten pieces or other numbers.
After confirming that PCB prototype production and testing are all right, small and medium batch production and mass production can be carried out and electronic products can be put into the market.
PCB prototype manufacturing can be divided into two ways: regular PCB Circuit Board factory and professional PCB prototype manufacturing company.
Regular factories produce PCB prototypes in order to have batch orders, so of course they want to return orders; PCB prototype manufacturers themselves only do prototypes or small batches, if there is a batch orders generally can not do.
In terms of quality assurance, it is certain that regular factories do better than PCB prototype manufacturing companies. Prototype manufacturing companies are One-Hammer Business. After prototype production is completed, prototype will be sent to you, and then payment will be received. they will not normally carry out flying probe testing. If the quality is not up to you, you have to retake it. Regular factories generally do flying needle testing, from material to process are meticulous and professional, so the quality is often successful once.
A PCB project involves a lot of things, if a product has problems in a certain link, it will easily affect the product development progress; PCB Board making is also the same, generally a project, designed PCB will go to prototype manufacturing, do a few boards for testing, if the test passes, all OK, then you can find batch manufacturers in the future. Direct mass production, the price will be much lower than the prototype manufacturer, prototype manufacturer prototype production is mainly highlighted fast.
What are the benefits of PCB prototypes?
Before mass production, we recommend that you use PCB prototype design services for functional testing of new products. The benefits of developing PCB board prototypes include:
If there are any errors, quickly test and correct the design - after waiting more than a week for the board, you will be anxious to get them into your application. You can do this when you pre-test your design with a PCB prototype.
Detection of any early potential design defects-PCB prototype design service allows you to discover any design problems within a few days and correct design errors in time before putting them into production.
Order a small amount of production, MOQ only has five boards if necessary - save money and reduce risk by delaying large orders until you know you have the type of sheet you need.
Benefit from lower production tolerances - It offers a clear indication of how well your PCB will perform
Once the Prototype Board can meet your quality and performance requirements, you can carry out comprehensive production. Then, we will transition from PCB Prototype Board service to standard PCB Manufacturing service, providing stricter production tolerances and more advanced options, including free manufacturing design (DFM) checks, to detect potential problems that may reduce the quality of PCB.
While it may be tempting to simply order your full printed circuit boards and decide you`ll deal with any design flaws that arise as they come, it`s rarely the most efficient solution. You may get the boards out sooner, but if something goes wrong, it could prove to be a lot costlier and more time-consuming than taking an extra few days to test a prototype.
