The SMOBC process and plugging method are used for pattern electroplating and lead and tin stripping, with steps including copper clad board preparation, lead and tin removal, solder mask patterning, plating, and hole plugging. The plugging method involves drilling, copper plating, hole blocking, etching, and hole plugging ink removal for hole plugging. Alternatively, the masking hole process can be used for precision hole plugging without ink cleaning.
