FAQ:
1. May I ask how you guarantee the quality of the products?
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. Every production process will have the special quality control.
2. What services can you supply ?
We are a manufacturer providing OEM PCB and PCBA producing services for more than 10 years. We can provide one stop services from PCB producing, components purchasing, assembly, quality control, ect.
3. What file we need to prepare if we want to get an quotation from you?
For PCB and FPC quotation, please show us Gerber files and specification.
For PCBA and FPCA quotation, please show us Gerber files, specification and BOM list.
3. Can I receive samples to test your quality ?
Yes,it is reasonable to get sample to test quality at first,but you should pay for samples,and we will return all sample cost in future mass production if the the gross cost of batch order has reached to a certain amount.
4.To what acceptability standards do we build?
A: IPC A600 Class 2 through IPC 6012 Class 3A
5.Where should you send your files to get a printed circuit board quote or place an order?
A: You can simply send us an inquiry via Alibaba site. Very soon our sales person will contact you for your inquiry/files. Or you can send your inquiry/files to our email address
