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.

ENIG Flex PCB – Electroless Nickel Immersion Gold, 3μ” Au Thickness

Product Details

The ENIG Flex PCB provides a highly solderable, flat surface critical for fine-pitch surface-mount technology (SMT) and complex routing in constrained spaces. Tailored for hardware engineers and procurement teams, this board utilises a 3μ” Electroless Nickel Immersion Gold finish to prevent copper oxidation, maintaining stable conductivity and extending component lifespan in dynamic environments.

Key Features of Our ENIG Flex PCB

Surface Finish: Electroless Nickel Immersion Gold (ENIG) with 3μ” Gold (Au) over 118-236μ” Nickel (Ni).
Base Material: Polyimide (PI) substrate offering excellent thermal stability and mechanical flexibility.
Coplanarity: Ultra-flat pad surfaces, essential for BGA (Ball Grid Array) and fine-pitch QFP placement.
Durability: Engineered to withstand repeated bending cycles without compromising electrical pathways or causing micro-fractures.
Standard Compliance: Manufactured to strict IPC-6013 Class 2 and Class 3 standards for flexible printed wiring.

Applications

Medical diagnostics and wearable health monitors requiring compact, bendable circuits.
Aerospace instrumentation and lightweight satellite communications.
Automotive sensors, including ADAS modules and compact infotainment systems.
Industrial automation equipment needing robust, space-saving interconnects.
