FAQ
Q: What files are used in PCB production?
A: PCB production requires Gerber files and PCB manufacturing specifications, such as the required substrate material, finished thickness, copper layer thickness, solder mask color, and design layout requirements.
Q: When can I get a quotation after I provide Gerber, product process requirements?
A: Our sales staff will give you a quotation within 1 hour.
Q: Can poor solder paste printing occur during the pick-and-place process for gold finger PCB?
A: Yes, if solder paste printing is poor and the printing is repeatedly executed, it may lead to printing quality issues without the need for cleaning. To solve this problem, cleanliness during the printing process should be ensured to avoid quality issues caused by repeated printing.
Q: How thick can your thickest copper be?
A: We could make 10 OZ copper foil.
