Take a look at this footprint. We’re looking at the solder-side of a DB-25 connector footprint. Given all the SMT and HDI (high density interconnect) we see these days, this looks primitive; like it could be straight out of 1979 or something. But it is a recent PCB design. Some of those good old-standard parts still have a place in today’s world.
However, old or new, issues can still pop up. So, just what do you see wrong with this one? At least two issues are pretty obvious, and a third may be open to debate.
What’s wrong with this picture?
