I don't, My desk causally is piled with papers, programming printouts, PCB's with defects to be resolved, and spare/broken parts from the SMT machines. For me its more important to help the SMT department and SMT Inspection department get better or

Even though you may find a pad-pad thru-hole spacing, part body size, orientation, and insertion head tooling clearences may be the deciding factor in spacing. 1. Part body diameter will dictate component centroid spacing. ---[][][][

In the IPC-SM-782 (Surface Mount Design and Land Pattern Standard) it recommends a minimum of .040" between bottomside wavesoldered chip pads. Where might I find a similar IPC recommendation for minimum space between thru-hole pads? Does anyone kno

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?
