Cirexx International

What Cirexx International does

Cirexx International, Inc. is a privately held US electronic manufacturing services (EMS) company founded in 1980 and headquartered in Santa Clara, California. The company operates a fully integrated 100% USA-based PCB production facility offering end-to-end services spanning PCB layout, fabrication, and assembly. Its technical scope spans rigid, flex, rigid-flex, RF/microwave, HDI, high-frequency, heavy copper, high-TG, hybrid, and metal-core circuit boards, with advanced capabilities including 4-mil laser-drilled micro-vias, 3-mil trace/space, +/-10% impedance control, buried capacitance/resistance, sequential lamination, stacked vias, and high-temperature (600°C) lamination with vacuum-assist presses. Assembly capabilities include BGA, wire bonding, SMT, X-ray inspection, and turnkey, consigned, or partial-turnkey engagement models.

The company sells exclusively to enterprise and government customers via B2B direct sales — quote-based pricing, web quote requests, phone, and field sales — and generates revenue primarily through per-project fabrication and assembly orders, including a quick-turn service layer that delivers prototypes in as little as 24 hours at premium pricing. The customer base is heavily weighted to defense/aerospace (NASA, Lockheed Martin, TRC Solutions), medical (Texas Instruments, Varian Medical), and industrial segments, supported by AS9100D, MIL-PRF-31032, ITAR, and J-STD-Space certifications. Pricing is non-public, quote-based, and dependent on material, layer count, tolerance, surface finish, and turnaround. Marketing is content-driven (blog, downloadable guides, case studies, supplier-diversity events) rather than paid. The company has 160 employees and reports 875,000+ uniquely engineered jobs completed across its 46+ year operating history.

The business model is high-mix, low-to-mid-volume specialty manufacturing targeting programs where certification, domestic sourcing, complex construction, and speed are valued above unit cost. Notable equipment investments cluster in 2012 and 2018 (ATG flying probe, Excellon COBRA laser, Orbotech inkjet, Glenbrook X-ray, OEM high-temp presses, Dynachem laminator, NTO HASL), and certifications were upgraded to AS9100D and expanded MIL-PRF-31032 in 2018, consistent with a deliberate deepening of defense and aerospace penetration rather than scale-oriented volume growth. No funding rounds, M&A, or leadership transitions are disclosed.
