FAQ

We require the complete PCB files (Gerber, other PCB files,etc.), Centroid (Pick & Place PNP file, XY data, or other formats), BOM, and all other necessary documents, images, or photos are complete for the assembly process work.

We hope you can mark on any individual package or box with the corresponding line number on BOM, manufacturer’s part# or customer’s part#, quantities. A detailed packing list is preferred to enable us to count and check upon receipt of your parts.

Yes. This practice is called partial Turn-key. You can supply some parts, and we source the rest of the parts on your behalf. We will ask for your approval for anything that is not sure at our side. In case parts crossing or substitution is needed, we will again ask for your final approval.

We offer functional testing, electrical testing, visual inspection, Automatic Optical Inspection (AOI), and other testing services to ensure product quality.

Yes, we offer comprehensive visual inspection services to ensure the accuracy of component placement and soldering, and that it meets your requirements.

Excess parts may be present due to our practice of requesting a percentage of overage for consigned or kitted orders, or purchasing extra for turnkey orders. For any unused parts, you can choose to have them shipped back with your PCBA or stored in our warehouse for future orders. The decision is yours.

You can submit your order by sending the necessary files (such as BOM, Gerber, Centroid files, etc.) to our designated email address.

We strictly adhere to IPC-A-610 and ISO 9001 quality management systems, and use a combination of automated testing and manual inspection to ensure every assembled board meets the required standards.

1)Please provide feedback and describe any defects either online or via email.
2)We would appreciate it if you could return some of the defective PCBs for further analysis.
3)Based on your feedback, we will ask the relevant departments to form research teams and hold meetings to analyze, discuss, and propose appropriate solutions.

For Turn-key orders, the lead time mainly depends on the speed at which we can source all the necessary components. We will keep you updated through daily email communication. While waiting for all parts to arrive, we will proceed with fabricating the PCBs and preparing the stencil, so assembly can begin as soon as the components are available.
