Relevant introduction of aluminum printed circuit boards
(PCB) is a kind of PCB:Aluminum printed circuit board (PCB) is a kind of metal base copper clad board with good heat dissipation function. Generally, a single panel is composed of three layers, which are circuit layer (copper foil), insulation layer and metal base. For high-end use there is also a design for double panels, the structure of the circuit layer, insulation layer, aluminum base, insulation layer, circuit layer. Very few applications for multilayer board, can be made of ordinary multilayer board and insulation layer, aluminum base laminated.
Single aluminum substrate: is only one layer of conductive graphics layer and insulation materials plus aluminum (substrate).
Double-sided line aluminum substrate: there are two layers of conductive graphics layer and insulation material plus aluminum (substrate) superimposed together.
Multilayer printed aluminum-based circuit board: a printed circuit board made by bonding three or more layers of conductive graphics with alternating layers of insulating material and aluminum (substrate).
According to the surface treatment method to be divided into:
Gold plate (chemical thin gold chemical thick gold selective gold deposition)
Electrogold plate (full plate electrogold finger selective electrogold)
Tin jet plate
Molten tin plate
Heavy tin plate
