What Promex Industries does

Promex Industries is a privately held, family-owned contract manufacturer founded in 1975 and headquartered in a 30,000 sq-ft production facility in Santa Clara, California. The company provides precision packaging and assembly services for complex microelectronic devices, with integrated capabilities spanning wafer dicing and thinning, die preparation, surface mount technology (SMT), flip chip assembly, wire bonding, substrate design and fabrication, laser micromachining, and final box build — all delivered "under one roof" through a structured Phase Gate Process (feasibility, development & optimization, process validation, preproduction, production). Its distinctive technical focus is heterogeneous integration (HI), the assembly of mixed-technology system-in-package (SiP) solutions that combine semiconductor dies with optical, fluidic, chemical, piezoelectric, and other non-electronic components.

The company's customer base is concentrated in regulated and high-reliability end markets, with medical devices and biotechnology as the primary vertical (FDA Class II/III assemblies, neuromodulation implants, lab-on-a-chip diagnostics), supported by activity in semiconductors, photonics, MEMS/sensors, data/telecom, and military/aerospace. Promex operates through a wholly-owned subsidiary, QP Technologies (formerly Quik-Pak, acquired 2015), located in Escondido, California, which handles prototype and small-volume IC packaging. The company holds ISO 13485:2016, ISO 9001:2015, and ITAR registrations, and maintains Class 100 and Class 1000 cleanrooms. Revenue is generated through quote-based, project-specific contract manufacturing engagements with enterprise customers via a direct consultative sales motion; pricing, revenue figures, and customer concentration are not publicly disclosed.

Governance is led by CEO Richard (Dick) Otte (MIT/Harvard, IEEE award recipient, 50+ years industry experience) and President/COO David Fromm (Stanford PhD, appointed 2026), with a leadership team recently expanded to include dedicated VPs for finance, military projects, and senior commercial roles. Promex serves customers across North America with no disclosed international footprint.

Direct peers

• Amkor Technology: One of the world's largest OSAT providers offering wire bond, flip chip, and advanced packaging (2.5D/3D, chiplet) services across consumer, automotive, and high-performance computing. Directly comparable in core assembly services, though much larger scale and broader end-market exposure than Promex's specialty HI focus.
• ASE Technology Holding: Global #1 OSAT with end-to-end semiconductor packaging and test services, including SiP, flip chip, and 2.5D/3D IC packaging. Most comparable in terms of service breadth and advanced packaging capability, but at vastly larger scale and with different end-market mix.
• Powertech Technology (PTI): Major Taiwanese OSAT offering memory and logic packaging, including advanced flip-chip, wafer-level packaging, and system-in-package. Comparable in assembly services portfolio; differs in being a tier-1 supplier to memory IDMs and consumer fabless, whereas Promex is a specialty HI shop for regulated industries.
• UTAC Holdings: Singapore-headquartered OSAT providing analog, mixed-signal, and advanced packaging including heterogeneous integration and SiP. Directly comparable in the HI/SiP service line, with particular overlap in automotive and industrial end markets.
• Hana Microelectronics: Thailand-based EMS and IC assembly provider serving consumer, industrial, and automotive with assembly, wafer-level packaging, and SiP capabilities. Directly comparable in offering integrated assembly for specialized end markets, with similar exposure to high-mix, low-volume customer programs.
• ChipMOS Technologies: OSAT focused on memory and mixed-signal IC packaging and test, with growing exposure to advanced packaging. Comparable as a contract assembly peer, though more concentrated in display driver ICs and memory than Promex's medical/mil-aero specialty.

Broad incumbents

• Jabil: Global tier-1 EMS with extensive healthcare, aerospace/defense, and photonics capabilities, including microelectronics assembly services. Comparable in regulated-industry contract manufacturing and complex integration, but at enterprise scale with a much wider service portfolio.
• Benchmark Electronics: US-headquartered EMS with deep exposure to medical, aerospace/defense, and industrial end markets — significant customer overlap with Promex's verticals. Comparable as a US-based contract manufacturer for regulated industries, though much larger and broader in scope than Promex's microelectronics-only focus.

Emerging players

• Deca Technologies: Specialty advanced-packaging company pioneering fan-out wafer-level packaging (FOWLP) and M-Series™ chiplet integration for the chiplet era. Most directly comparable emerging peer in the HI/chiplet design philosophy that Promex's HI practice is built around.
• Palomar Technologies: Specialty provider of precision die-bonding and packaging equipment plus assembly services for photonic, RF, and microelectronic devices. Comparable in the high-precision, low-volume, customized-assembly niche that Promex serves in photonics and mil-aero.
