What is aluminum PCB?

Release Date:2020-02-14

Aluminum PCB is a metal based copper clad laminate with good heat dissipation function. The general single panel consists of three layers, namely, the circuit layer (copper foil), the insulation layer and the metal substrate. Common in LED lighting products. There are positive and negative sides. The white side is welded with LED pins, and the other side shows aluminum color. It usually spreads with heat conduction condensate and then contacts with the heat conduction part. There are ceramic substrates and so on.

What is PCB board?

PCB generally refers to printed circuit board. Printed circuit board {PCB circuit board}, also known as printed circuit board, is the electronic component electrical connection provider. Its development has a history of over 100 years. Its main design is layout design. The main advantage of using circuit boards is to greatly reduce the wiring and assembly errors, improve automation level and production labor rate.

According to the number of PCB, it can be divided into single panel, double-sided board, four layers, six layers and other multi-layers PCB. Because printed circuit boards are not general terminal products, the definition of names is slightly confused. For example, motherboards used in personal computers are called motherboards, and they can not be directly referred to as circuit boards. Although there are computer boards in the motherboard, they are not identical, so the evaluation of industries can not be the same. Another example: because the integrated circuit parts are loaded on the circuit board, the news media call him IC board, but in essence, he is not equivalent to printed circuit board. We usually say that PCB refers to bare boards, that is, no PCB PCB.

The difference between aluminum PCB and  PCB

For some small buddy who just engaged in aluminum pcb industry, there is such a question. That is, what is the difference between aluminum substrate and PCB board. For this question, the next we will tell you specifically what differences are there between them?

PCB board and aluminum base plate are designed according to the requirements of PCB board. At present, the aluminum base PCB board in the market is generally single-sided aluminum base plate. PCB board is a large category. Aluminum base plate is only a category of PCB board, and it is aluminum base metal plate. Because of its good thermal conductivity, it is generally used in LED industry.

Generally speaking, the PCB board is copper substrate, which is also divided into single panel and double sided board. The material used between them is very different. The main material of aluminum PCB is aluminum plate, and the main material of PCB board is copper. Aluminum substrate is special for its PP material. Good heat dissipation. The price is also quite expensive

In comparison with the heat dissipation, the performance of aluminum PCB in heat dissipation is superior to that of PCB board. Its thermal conductivity is also different. Aluminum PCB is a kind of PCB, and the price of aluminum PCB is more expensive.
