Alpha Circuit manufactures high-reliability printed circuit boards for defense, aerospace, medical, automotive, and advanced commercial systems, serving OEM and EMS partners requiring precision, traceability, and consistent electrical performance.

Its capabilities include laser-drilled microvias, stacked and staggered vias, via-in-pad, high aspect ratio plated through-holes, and integrated D-coupons for embedded impedance verification and process control. These technologies enable dense, high-speed digital, RF, and mixed-signal designs where dimensional accuracy and signal integrity are critical.

Alpha Circuit produces complex multilayer boards exceeding 30 layers, including hybrid stack-ups, copper and metal-core substrates, heavy copper plating, and specialty laminates for high-frequency and thermally demanding environments. Surface finishes include ENIG, immersion silver, immersion tin, OSP, and leaded and lead-free HASL.

Certified to AS9100, ISO 9001, and IATF 16949, and fully ITAR compliant, Alpha Circuit manufactures to IPC Class II and III standards, with full PPAP and AS9100 FAIR reporting—delivering precision interconnect platforms for mission-critical electronic systems.

The result is a fabrication partner delivering precision-engineered interconnect platforms capable of supporting the electrical, thermal, and mechanical demands of modern high-performance electronic systems.
