General Introduction of Multilayer PCB

As the name suggests, a multi-layer circuit board can only be called a multi-layer circuit board with more than two layers, such as four layers, six layers, eight layers, and so on. Of course, some designs are three-layer or five-layer circuit, also called multi-layer PCB circuit board.

Conductive wiring diagram larger than the two-layer board. The insulating substrate is separated between the layers. After each layer of the circuit is printed, each layer of the circuit is overlapped by pressing. After drilling, the electrical connection between them is usually achieved through plated through holes on the cross section of the circuit board.

General Introduction of Aluminum PCB

The aluminum substrate is a metal-based copper-clad plate with good heat dissipation function. Generally, the single-sided board is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer, and a metal base layer. Aluminum substrates are rarely made into double-sided circuit boards, and double-sided circuit boards will affect its heat dissipation and other functions. Aluminum substrates are commonly used in LED lighting, such as: industrial led light boards, automotive car light boards, medical surgery LED light boards, display screen led light boards and so on. The aluminum substrate has both front and back sides. Usually the back side is unpackaged and presents the true color of aluminum. On the other side, the white side is soldered to the LED pins. Generally, the thermally conductive paste is applied to the thermally conductive part after contact. There are ceramic substrates and so on.
