4.FAQ
Q: Which type of PCBs do you expert in?
We are specialized in producing HDI multilayer blind, BGA, impedance, half-hole, double-sided, single-sided, etc. 

Q: Experience?
We are OEM on PCB boards with experience over 9 years. 

Q: What is your Lead time?
Lead time is usually punctual here, for some special situation, we can also advise customer in advance to avoid any inexpectation or loss at customer side. 

Q: What is your testing policy and how you control the quality?
For sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there’s many steps to PCB production, we usually do inspection after every step. 

Q: What is your certificate?
ISO/TS16949: 2000, ISO14001: 2004, UL, SGS, CE&RoHS report. We can provide the report of raw material based on customer’s requirement. 

Q: What is your package?
With Inner vacuum package and out carton. 

Q: PCB shipment?
This is depend on customer, sometimes we ship through our forwarder, who is also the agency of DHL, TNT, UPS, Fedex, and so on. Our forwarder can provide too much better freight cost than we get directly from those express enterprise.
