Technical learnings and practical tips from the DeltaProto PCBA proto lab.
One extra V-score would have saved the whole panel
2026-09-09Despite preheating, the panel delaminated. And because the PCBs were still connected to each other, we could no longer process the remaining ones separately.
Gerber and drill layers misaligned? The absolute-vs-relative origin bug
2026-06-29Drill holes floating off your board in a Gerber viewer? It is usually an Altium absolute-vs-relative origin mismatch. Here is how our actively maintained open-source Gerber/Excellon drill library detects and fixes it automatically.
