Electronic Components Sourcing

Sourcing high-quality electronic components is essential to create quality products for your brand. Choosing the right parts ensures that your products are functional and useful for end users.

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.

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.

PCBSync Fine Line Rigid-Flex PCB (3 mil Trace Space) with ENIG

Product Details

Achieve unmatched precision with the PCBSync Fine Line Rigid-Flex PCB, engineered for designers who demand ultra-tight tolerances and long-term reliability. Featuring an industry-leading 3 mil trace and space capability, this rigid-flex PCB is purpose-built for high-density interconnect (HDI) applications where space and signal integrity are non-negotiable.

Why Choose PCBSync Fine Line Rigid-Flex PCB?

The rigid-flex PCB design combines the structural stability of a rigid board with the dynamic flexibility of a flex circuit — all in one seamless solution.
