Infrared remote control transmitter for TV game console based on 66C27

Most video game consoles are "wired". This type of operation is simple, but the operating distance is limited and the wires are prone to failure. In this circuit, when S0 in the transmitter is grounded, it can be used as the No. 2 machine, and when S0 is connected to +5V, it is used as the No. 1 machine. The transmitter can be powered by 4 AA NiCd or NiMH batteries. The D1 pin of the 66C27 is used to drive the LED for the emission indication. If the illumination is weak, the battery should be replaced.

Aluminum Base Board

What is IMS PCB?

ims PCB is aluminum substrate PCB, which also means printed circuit board, but the material of the circuit board is aluminum alloy. In the past, the material of our general circuit board was glass fiber, but because the LED heats up, the circuit board used in LED lamps is generally It is an aluminum substrate, which can conduct heat quickly. The circuit boards for other equipment or electrical appliances are still glass fiber boards!
The aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single panel is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. For high-end use, it is also designed as a double-sided board, and the structure is circuit layer, insulating layer, aluminum base, insulating layer, and circuit layer. Very few applications are multi-layer boards, which can be formed by bonding ordinary multi-layer boards with insulating layers and aluminum bases.

The aluminum substrate ims is made of polymer (mainly epoxy resin) filled with ceramic powder with high thermal conductivity and high insulation. Such an insulating layer has good thermal conductivity (the thermal conductivity is as high as 2.2/mK), which is very high. The insulation strength, good bonding performance. At the same time, in response to market demand, Bergquist has developed an insulating layer that is whiter than its competitors, and other properties are also outstanding. It has improved the reflectivity of high-power LED white solder masks, and has become a new weapon in the high-power LED market.
Aluminum substrate ims (metal-based heat sink (including aluminum substrate, copper substrate, iron substrate)) is a low-alloyed Al-Mg-Si series high-plasticity alloy plate, which has good thermal conductivity, electrical insulation properties and mechanical processing properties Compared with the traditional FR-4, the aluminum substrate adopts the same thickness and the same line width. The aluminum substrate can carry higher current. The aluminum substrate can withstand voltage up to 4500V and the thermal conductivity is greater than 2.0. In the industry, the aluminum substrate is used Mainly.
