1. 2-layer aluminum pcb Product Introduction:
The 2-layer aluminum substrate pcb inherits the metalness and safety of the 1-layer aluminum base pcb, and can realize the complex and precise wiring of the ordinary PCB (FR4 PCB). The 2-layer aluminum substrate pcb perfectly applies the characteristics of heat dissipation aluminum, conductive copper, insulating resin, and thermal film to electronic circuit boards. The 2-layer aluminum substrate pcb can be independently wired on both sides of the product, and can communicate with the lines on both sides through electroplated via holes to form a larger network. Make the wiring design of the 2-layer aluminum substrate pcb more flexible, which can meet more complex work areas. It can realize the filling of "SMT", wiring and binding on both sides of the product. The 2-layer aluminum substrate pcb integrates high-efficiency thermal conductivity, heat dissipation, insulation safety, and long service life.
