HUIHE Circuits heavy copper pcb manufacturer adds a certain value according to the area value calculated by the computer and the empirical constant accumulated in the actual production to ensure the integrity of the plating layer in the hole. 2. When the heavy copper PCB is electroplated for 5 minutes, take out the substrate and observe whether the copper layer on the surface and the inner wall of the hole is intact. It is better that all the holes have a metallic luster. 3. A certain distance must be maintained between the substrate and the substrate. 4. When the heavy copper PCB reaches the required electroplating time, a certain amount of current must be maintained during the removal of the substrate to ensure that the surface of the substrate and the hole will not be blackened or darkened. 5. HUIHE Circuits heavy copper pcb manufacturer according to the mechanical processing floppy disk for trial processing, the first part pre-inspection is carried out, and all the workpieces are processed after meeting the technological requirements.
