5.FAQ
Q:What is your Lead time?
Lead time is usually punctual here, usually 5-10 days for PCB sample, 10-15 days for mass production. 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 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. 

Q:What is your produce ability?
Our ability is average 300,000 square meters per month. 

Q:Will you allow me to put several part number together into one panel?
Yes, this is usually happen in we factory, this way can help customers reduce some cost and to a certain degree, it can help reduce some assembly cost. 

Q:What is your minimum order quantity?
We have no limitation on MOQ, prototype, medium volume and large volume are all acceptable.
