1. What service can we supply?

We focus on producing PCB & PCBA since 2004. we also provide turnkey solution including RD, PCB fabrication,SMT ,Function testing and other value-added service.

2.What kind files need for a customized PCB or PCBA order?

For PCB board, you need to prepare files of Gerber file,it should including RS-274X,ODB++, DXF, PCB, PCBDOC etc formats.
For PCBA the file for PCB, the BOM list (components list), Pick and Place file(txt format), real sample pictureor 3D PDF version file etc.

3.How do you ensure confidentiality of the documents ?

We are willing to sign NDA effect by customer side local law and promising to keep customers data in high confidential level.

4.Do you provide samples? Is there minimum order quantity for assembly?

Yes we can provide free samples, price and shipping cost open for negotiation. and there is no minimum order quantity.

5.How to control products with high quality? 

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

6.What are your PCB assembly quality standards?

We manufacture PCBs to meet IPC-A-610 Class 2 specifications as thedefault,supported by inspection and test crite-ria estiblished by IPC.
