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 presence of side etching and the requirement for accurate tracing, some compensation must be made during the production of the artwork. However, the compensation needs to be confirmed based on the thickness value of the side etching, as the artwork is negative.
- During the process of aluminum PCB layer image, it usually uses a 0.3 mm epoxy board, which has the same size as the aluminum PCB board. Tape is used to block and compact it to avoid solution infiltration. After treating the copper surface, the best method is to use chemical micro etching. After baking, it should be treated with a 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.
