Hello

I am facing a problem with fine pitch SMT component of 20mils. How can the soldermask be applied in between the pads without covering them? My supplier claims that their process capability is restricted.

Another Question:
Which PCB manufacturing house in Singapore can produce 6mils trace/air-gap (for internal layers as well) specifications?


Please Advice...Thanks
