FAQ:
Question: What is the most common quality issue for this kinf of pcb?
Answer: 1) Copper burr in half holes
2) Oxidation in half holes
Question: Why use surface treatment ENIG+OSP?
Answer: OSP has good tin solder paste feature . The BGA size is only 8mil. If use immersion gold, it's not good for tin solder paste. So we suggest customer to use ENIG+OSP. It can protect other pads well and meanwhile, it makes sure that the BGA pads have good tin solder paste feature.
Question: Is the cost for ENIG+OSP higher than ENIG?
Answer: Yes it is. But it won't make a big difference.
