Gerber Viewers. Nothing makes an engineer more nervous than a “tape-out” – that moment you send files off to a manufacturing house for PCBs (or chips). Will the returned product be correct, letting you continue onto manufacture? Or will there be a (dumb) mistake, setting you back 3 weeks and hundreds to thousands of dollars? Even the best engineers I know still get antsy and nervous in the lead up to a release!
That’s why its so important to do everything you can to avoid problems. Now, there’s not one engineer out there who has done nothing but fab perfect designs each time. Heck, even Microsoft had XBox manufacturing problems, they happen! But every step you take to avoid an easily-fixable problem is worth your attention.
Before we send of PCBs, of course we do a ERC/DFM check inside the software but even then, we always take a look at the final GERBER files before they are zipped up and sent off to the fab house.
