Quotation requirement:
-gerber file would be the best to get an accurate quotation. If no, following specifications are needed for pcb quotation.
1. Quantity
2. Base material
3. Layer count
4. Board thickness
5. Copper thickness
6. Surface treatment
7. Color of solder mask
8 other special requirements

Pcb assembly files requests:
1. Gerber files of the bare pcb
2. Bom (bill of material) for assembly
To shorten the lead time, please kindly advise us if there is any acceptable components substitution.
3. Testing guide & test fixtures if necessary
4. Programming files & programming tool if necessary
5. Schematic if necessary
