FAQ

With Transportation Do We Use?

For small quantity, we will use express such as DHL, UPS, FED, TNT to send the goods.For mass production batch, we will use sea transportation for you.

With Payment Terms Do We Accept?

For sample order or small batch, we suggest you to use Pay-pal and Western Union.For mass production batch, we suggest you to use T/T.

How Can We Guarantee You Receive An Good Quality Product?

For PCB, we will use Flying Probe Test, E-test etc. for it.

For PCBA, we need you to offer us a method or test fixture for the function test.Before that, our inspectors will use microscope and X-ray to check the IC footwelding or bad solder etc.

How About The Delivery?

Normally, for sample order, our delivery is about 5 days.For small batch, our delivery is about 7 days.

For mass production batch, our delivery is about 10 days.

But that depends on the real condition when we get your order.

If your order is urgently please contact us directly ,we will priority to deal it and do ourbest to give you satisfied delivery time.

How Long Does It Take For PCB And PCBA Quote ?

PCBs quotation within 2 hours can finished the PCBA depend on the components quantity,if simple, within 6 hours can finished,once complex and more,the 12- 36 hours can be finished.
