Foxtronics EMS assembles rigid and HDI PCBAs using advanced fabrication partnerships. Our process engineers work closely with your team to define stack-ups with controlled impedance, balanced copper distribution, and low-loss dielectrics.
Because these dense interconnects operate at the edge of performance, we embed Design for Manufacturability (DFM) and Design for Test (DFT) reviews early. You’ll receive actionable input on trace/space limits, via-in-pad planning, copper wrap, aspect ratios, CAF mitigation, and thermal relief long before tooling begins.
From automotive ADAS and aerospace sensors to compact medical devices, our expertise accelerates development, improves first-pass yield, and ensures consistency from prototype to production.
Rigid PCBs use solid substrates like FR4, polyimide, or high-Tg laminates to provide mechanical stability and structural integrity. They’re standard in most electronics where durability and form retention are critical.
HDI (High-Density Interconnect) PCBs build on this foundation with microvias, fine-line routing, blind and buried vias, and via-in-pad designs, enabling tighter component spacing and high-speed performance in compact formats.
By combining rigid substrates with HDI architecture, designers achieve complex multilayer layouts that balance electrical performance, thermal management, and mechanical strength, ideal for high-reliability applications.
We assemble complex rigid and HDI boards designed for speed, density, and reliability. From high-layer-count rigid boards to ultra-dense HDI constructions, we deliver the technical sophistication needed for today’s electronics.
