1、 Introduction to Single sided Insulated Hole Aluminum Substrate:
Due to the fact that metal core aluminum is a conductor and cannot fix DIP components, insulation hole technology is the solution to this problem.
The insulation hole aluminum substrate material is composed of aluminum plate (5052), dielectric layer, and copper layer. The difference between insulated hole aluminum substrate and single-sided aluminum substrate PCB is that the aluminum is pre drilled, filled with epoxy resin adhesive, and the dielectric layer and copper layer are pressed onto it. The main convenience for DIP components is to pass through the gaps in the aluminum through the wire through holes to maintain electrical insulation. The aluminum core can allow for electrical connection and insulation through holes, which is called the insulation hole aluminum substrate.
