A:The more detailed the data supplied, the faster and more accurately we can quote. We firmly abide by the "if in doubt - ask" principle. Ideally we ask for the following:
(1) Gerber data comprising every 'layer' required to manufacture and supply the PCB with a descriptive exported 'read me' file.
(2) PCB fabrication requirements including Number of Layers, Board Thickness, Board Material, Copper Thickness, Color of Solder Mask and Finish.
(3) A comprehensive bill of materials (BOM) itemizing:
a: Component Part number and description (include rating value and tolerance where applicable).
b. Reference designators with corresponding quantities
c. Component manufacturer
d. Indicate approved alternate components
e. If firmware is required, please list each firmware as a BOM line item (Including revision)
(4) Any other construction information, i.e. details of any mechanical assembly, fabrication information for enclosures, wiring, artwork, programming and testing requirements.
