At a minimum we need gerber data, generally in RS274x format, Excellon drill file, PCB specification, BOM list, quantity and lead times.3.How long will it take to get a quote?We return domestic quotes the same day, usually within hours. Offshore quotes are generally returned within 24 hours.4.Do you handle PCB quick turnaround?We specialize in quick turns. We can turn 1-2layers boards in one day, for 4-6layers pcb we build them in 3-5 days.5.Can I get PCB prototypes from you?We have a very strong front end system and have capacity to handle several prototypes every days.6.Do you run a separate line for prototypes and production?No, we production tool everything. If your prototype turns into production, you won't incur any additional tooling charges.7.What file formats do you accept for PCB assembly?Gerber and CAM Auto CAD DXF, DWG formats 8.What is your record for "on time" delivery?We strive for 100%, but currently run 97-99% on time. url:http://www.oem-pcb.com
