My purchaser called three vendors (two PCB and one screen printing) and asked what their customers provide:
(1) Precision Technology (PCBs) says 95% of their jobs come in with SAE (English) dimensions and 5% with metric. They convert everything to SAE and check every dimension including the layout for each part on the board. (This "conversion" surprises me quite a bit). (2) Salt Lake Circuits (PCBs) sees 85% SAE and 15% Metric. (3) Anagraphica (screen printing) said only QSI and Palm use Metric, and Palm is actually a mix. If graphic artists are doing the work it is SAE; if engineers then it's Metric. (Palm has a large manufacturing facility here in SLC.)
