Inspection:

1. The main inspection hole metallization quality status, should ensure that the hole was no extra burr, black holes, holes and so on;
2. Check the substrate surface dirt and other unwanted objects;
3. Check the board number, drawing number, process documentation and process description;
4. clarify racking parts, racking requirements and can withstand the plating tank plating area;
5. plating area, the process parameters to be clear, to ensure the stability and viability of the electroplating process parameters;
6. conductive parts cleaning and preparation, the solution was presented first energization process active;
7. finds bath composition is checked, plate surface area status; such as the use of spherical anode bar installed, you must also check the consumption;
8. Check the voltage solid case and the contact area, the current fluctuation range.
