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.

Will my file be safe after you get it ?

Yes , we will not release your design to third party unless with your permission .And we can signthe NDA before you send the file.

Do you accept process materials supplied by clients?

Yes, we can provide component source, and we also accept component from client

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

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.

PCB: Quantity, Gerber file and Technic requirements(material,surface finish treatment, copper thickness,board thickness ,...) PCBA: PCB information, BOM, (Testing documents...)

Q:MOQ?

There is no MOQ in Smart.We are able to handle Small as well as large volume production with flexibility.

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.
