How to make a Double sided Metal (Aluminum) core printed ciruit board?
1. Drill Holes on the bare Aluminum Board
(The holes are larger than your PTH Holes in
2. Fill the holes by resin.
3. Laminate dielectric layer
Bettwen Aluminu bare board and two copper foil
4.Drill the holes as your design on the same place
that drilled on first step process
5.Plate through holes
6.Manufacturing trace layer etc….
Then Other process as FR4 PCB boards.
