Q: What is needed for PCB/PCBA quotation?
A: For Bare PCB project, please provide Quantity, Gerber file and specification like material, surface finish treatment, copper thickness, board thickness, soldermask color and silkscreen color and other special
Q: Are my files safe?
A: Your files are held in complete safety and security. We protect the intellectual property for our customers in the whole process.. All documents from customers are never shared with any third parties. We are willing to sign NDA effect by customer side local law and promising to keep customers data in high confidential level.
Q: What is your minimum order quantity (MOQ)?
A:Our MOQ is 1 PCS, sample and mass production all can support.
Q: How to calculate the shipping cost?
A:The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.
Q: What is your testing policy and how you control the quality?
A:Regarding to PCB samples, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by Electrical fixture which is faster. As to PCBA production, there are automated optical inspection (AOI) for each batch, X-ray inspection for BGA parts, first article inspection(FAI) before mass production.
