We’re writing a new tutorial on PCB manufacturing, and we’d like to add pictures of common PCB manufacturing errors. We’ll give out free PCB coupons in exchange for open source licensed images (limit 4).
Here’s the examples we need, the first two are the most important right now:
- via alignment problem (drill not centered in via copper)
- missing traces (over etching)
- shorts (under etching, as shown above)
