Oct 24, 2023 at 6:21 comment added Soldersmoke He has specifically asked for tracewidth, and not a pad layout. Yes, 20mil = 0.508mm. And no - there's no "100 pin tqfp" in the schematic shown
Sep 27, 2023 at 12:44 comment added Tim Williams @StephenCasey If you try putting 0.5mm -- or 20mil -- width traces into a 0.5mm pitch footprint, it won't exactly matter... neither one is going to connect to any of the pads!
Sep 27, 2023 at 11:24 comment converted from answer Stephen Casey I know this is an old post. But 20mil is NOT 0.5mm. It's 0.508mm. Not a big deal for trace width, maybe. But a real big deal for a 100 pin tqfp with 0.5mm pitch. The error across 25 pins accumulates to 0.2mm. I have just been burned by this - The engineer who created the footprint worked in Imperial units, and also used 20mil=0.5mm
