Insulated hole aluminum pcb
1.Insulated hole aluminum pcb
Insulated hole aluminum pcb product introduction：
Insulated hole aluminum pcb Since metal core aluminum is a conductor, DIP components cannot be fixed. Insulated hole technology is the solution to this problem-metal core PCB manufacturing process.
Insulated hole aluminum pcb material is made of aluminum plate (5052) + dielectric layer + copper layer. Insulated hole aluminum PCB is different from single-sided aluminum substrate PCB in that the aluminum is pre-drilled, the hole is filled with epoxy resin, and the dielectric layer and copper layer are laminated on it. It is mainly convenient for DIP components to pass through the gap in the aluminum to maintain electrical insulation. The aluminum core can allow electrical connections and insulated through holes, which is called Insulated hole aluminum pcb.
