FAQs OF ELECTRONIC MANUFACTURING SERVICES

What files should be sent to get a contract electronic manufacturing quote?

PCB gerbers, bill of materials (BOM), testing requirements, enclosure drawings, work instruction of box build and other optional documents such as schematic, quality warranty etc.


What's the lead time to get the first product sample generally?

Lead time is determined by molding (basically 30~45 days), PCBA (15 days simultaneously) and final box build. In general, it takes about 1.5 ~ 2 months to see the first product sample.


Can I get refund if the electronic manufacturing product is not satisfied?

Electronic manufacturing product is customized and can not be sold to other clients, so both parties should be careful to confirm all details and then head for prototype order. Since PCBA products are custom‑manufactured, we recommend prototyping before full production. If a quality issue arises due to our process, we will rework or remake the boards. Refunds are handled on a case‑by‑case basis—please confirm details with your sales contact before placing your order.
