What Naprotek does

Naprotek is a US-based electronics manufacturing services (EMS) provider focused exclusively on high-reliability applications in regulated and mission-critical end markets. Founded in 1995 and headquartered in San Jose, California, the company operates three purpose-built Centers of Excellence — Rapid Prototyping & Batch (San Jose), Streamlined Electronics Assembly (San Jose), and RF Assembly & Components (Londonderry, NH, via the SemiGen subsidiary) — supplemented by the Manchester, NH MicroFab operation for precision RF circuit fabrication. Its service platform spans printed circuit board assembly (PCBA), microelectronics assembly (die attach, gold/aluminum wire bonding, epoxy encapsulation, hermetic sealing), RF/microwave assembly and testing to MIL-STD, system integration and box build, supply chain management, and in-house wafer and thin-film foundry services. The SemiGen product line adds proprietary semiconductor and passive components, including PIN diodes, beam lead capacitors, tantalum nitride thin-film resistors, attenuators, and filters.

Naprotek serves six primary verticals — Defense, Space, Medical, Semi-Cap Equipment, Test & Instrumentation, and Advanced Technologies — with customers including BAE Systems, General Motors, Woods Hole Oceanographic Institute, MicroProbe, Lumileds Lighting, Broadband Wireless Technologies, Dynamic Test Solutions, and Opsis Health. The company holds ITAR registration, CMMC 2.0 Level 2 (covering both Naprotek and SemiGen), AS9100D, ISO 13485, ISO 9001:2015, RoHS, GDPR, and CCPA compliance, and operates ISO Class 7 and Class 8 clean rooms for microelectronics work. Pricing is quote-based, project-specific, and aligned to high-mix, low-volume production with rapid-turn prototyping as a key wedge (1–5 day quick-turn PCBs).

The business is privately held by Edgewater Capital Partners since December 2020, under which Naprotek has executed an aggressive platform-build via the acquisitions of SemiGen (October 2021), NexLogic (January 2022), and MicroFab (August 2022). Current leadership is led by CEO Tim Filteau (appointed late 2025), CFO James Eisenhaure, SVP Operations Anil Kumar, VP PMO Fida Mustafa, and VP Business Development Freddie Chavez. Go-to-market blends direct sales, channel partners (e.g., QuantumFlow for Southern California and Southwestern Nevada), and a heavy industry-events presence at IEEE IMS, IPC APEX, MD&M West, SPIE Photonics West, and SLAS. Major customer outcomes include over $9M in FY24 contract value tied to the Space Development Agency T1TL/T2TL programs and 18 successful space launches in 2024 using Naprotek-manufactured controller cards and electronic systems.
