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.

Product Details

The 12-Layer 3+N+3 HDI Stackup offers a robust platform for engineers and product developers managing complex routing within tight spatial constraints. By utilising three sequential lamination cycles (3+N+3), this advanced HDI PCB provides the necessary architecture to support micro-vias, buried vias, and fine-pitch ball grid arrays (BGAs). This structural integrity ensures reliable signal transmission and superior thermal management for high-density electronic applications.

Key Features of the 12-Layer 3+N+3 HDI Stackup

  • Layer Architecture: 12 discrete layers featuring a 3+N+3 sequential lamination build for maximum routing density.

  • Via Technology: Incorporates laser-drilled micro-vias, staggered vias, and buried vias to optimise internal space utilisation.

  • Material Options: Fully compatible with high-Tg FR4, Rogers, and Megtron substrates to support demanding thermal and electrical parameters.

  • Impedance Control: Manufactured with tight tolerance impedance matching, essential for high-speed digital signal integrity.

  • Surface Finish: Available in ENIG, ENEPIG, and Immersion Silver to guarantee ultra-flat pad surfaces for precise BGA placement.

Applications

  • Telecommunications: 5G routers, network switches, and cellular base stations.

  • High-Performance Computing: Enterprise servers, data centre infrastructure, and AI hardware accelerators.

  • Medical Electronics: Advanced imaging systems and portable diagnostic equipment.

  • Aerospace & Defence: Avionics, compact radar modules, and critical communication systems.
