In the manufacturing process of MCPCB/Aluminium PCB, people should pay attention to artwork manufacturing, material preparation, image transferring, etching, surface treatment and profile, etc.
- Due to the existence of the side etched, and must meet the accuracy of trace, thus, it must do some compensation when manufacturing artwork, but compensation must be confirmed according to the value of side etched with different thickness, the artwork is negative.
- During the process of aluminum PCB layer image, it usually uses 0.3 mm epoxy board, which the size is the same as the aluminum PCB board, and uses the tape to blockade and compaction to avoid solution infiltration. After the treatment on copper surface, the best way is to use the chemical micro etching, and then after baking it should deal with wet film to prevent oxidation.
- In the process of etching in Aluminium PCB, we need to use test boards to adjust the solution to ensure the best etching results.
- After etching on Aluminum PCB, the best way is to use SN solution to do strip immediately.
- choose a good supply.
