The Method of interconnection of PCB board
What are the Uses of Aluminum Substrates PCB?
Aluminum substrate is a kind of metal-based copper clad laminate with good heat dissipation function, and it is the basic material of high-power power electronic circuit structure technology and interconnection technology. In PCB proofing, the single-sided aluminum substrate is generally composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer, and a metal base layer; a double-sided board, the structure is a circuit layer, an insulating heat-conducting layer, an aluminum base, an insulating heat-conducting layer, and a circuit Floor. There is also a double-sided aluminum substrate, which is formed by mixing a glass fiber board and an aluminum base. The aluminum base PCB is on the bottom layer, the core board is aluminum, and the top and bottom layers are wired.
