Prototype Assembly

Our prototype runs are often a mix of large BGAs and tiny 0201 components, and we’ve had issues with other assembers on yield. PCBsync’s assembly team delivered a perfect first-run success. The board was pristine, the solder joints were impeccable under the microscope, and everything worked straight out of the box. Their attention to detail in the assembly process saved us weeks of debug time. They are now our go-to for critical prototype assembly.

Electronic Manufacturing

Scaling from hundreds to tens of thousands of units for our smart home device presented huge supply chain and manufacturing challenges. PCBsync’s full electronic manufacturing service was the solution. They didn’t just build the PCB; they managed the entire box-build, sourced all components (even during shortages), and implemented a rigorous quality control system that drastically reduced our field failure rate. They act as a true extension of our own production team.
