PCB Assembly

PCBBox offers PCB assembly services to meet your one-stop manufacturing requirements. As an EMS expert, PCBBox have advanced capabilities of SMD & through hole assembly (also including flexible printed circuit board) with 7 assembly lines. The accurancy could be down to 0201 chips and 0.25mm pitch for BGA. Samsung & Fuji SMT mounters well manage high-end requirements of PCB assembly, whatever in relation to mil-spec, network, communication, health care, medical, musical instrument application.

According to performance in past years, the pass rate was over 99.9%. Our team of incoming material quality control, in-process control and outgoing quality assurance will carefully inspect raw materials and your boards. Our engineering team will raise new production introduction (NPI) meeting to discuss about assembly manufacturing process once we get your order.
