Questions & Answers
Q: How can we ensure our information should not let third party to
see our design?
Ring PCB: We are willing to sign NDA effect by customer side local
law and promising to keep customers data in high confidential
level.
Q: What does XHT need for a customized PCB order?
Ring PCB : When you place a PCB order, the customers need to
provide Gerber or pcb file. If you do not have the file in the
correct format, you can send all the details related to the
products.
Q: What is your inspection policy? How do you control the quality?
Ring PCB: In order to ensure the quality of PCB products, flying
probe inspection is usually used; electrical fixtures, automatic
optical inspection (AOI), BGA parts x-ray inspection, first article
inspection ( FAI) etc.Ensure that every PCBA product undergoes 100%
quality inspection and is affixed with a QR code for product
identification.
Q: Can we inspect quality during production?
Ring PCB: Yes, we are open and transparent on each production
process with nothing to hide. We welcome customer inspect our
production process and check in house.
