What are people using out there for minimum spacing between vias ? We recently came across a PCB manufacturer that wants us to increase our spacing due to their process. Below is our current spec. that we follow. Spacing between via pad to via pad o

PTH to SMT spacing should be 80-100 thous. any closer will result in bridging. Scott

The pad spacings are 20 mills. I can send you a picture.

Russ is correct, but you may have variations between board density types also. Some ovens may be able to handle low density boards with no spacing, but need a zone's worth of spacing for high density boards. Other ovens don't need any spacing for a

What is the tightest spacing that you have assembled 0201 components? Under what assembly scenarios did you produce the best/worst yield at this spacing?

Depends on the oven I have found, I had one oven that required about an entire zone for spacing while another I found that I could put them in back to back with minimal or no spacing.

Has anyone else had problems with the space saver stencils and frames. The stencil tends to bow in the middle when clamped. These are the frames with only 2 pins to hold the stencil in place. Thanks for any advice
