Fathom's Rochester buys add circuit board, harness and full-rate production work
What the acquisition release says each company does, and what Fathom says the combination leaves it better positioned to support. CORE Industrial Partners announced its portfolio company Fathom's acquisitions Oct. 13, 2026.
Fathom's website capabilities menu lists no PCB assembly or wire harness work. CORE gave no price.

TCS adds printed circuit board assemblies and cable and wire harnesses, work that does not appear in the capabilities menu on Fathom's website.1–2 PGM reaches further along the volume curve than the announcement's description of Fathom. It supports aerospace and defense customers from low- and mid-volume manufacturing through full-rate production, while Fathom describes its own production services as low- to mid-volume.1
PGM's website says it is involved with "many critical programs for our armed forces" and makes components and assemblies for areas including electronic protection (countermeasures) and RF housings and covers.3 Both TCS and PGM hold AS9100 certifications and International Traffic in Arms Regulations (ITAR) registrations. The announcement says TCS serves customers primarily in aerospace and defense but gives no split between defense and commercial aerospace work at either company.1
Fathom says the combination leaves it better positioned to support customers from early-stage development and prototyping through qualified, sustained production. What has already changed is ownership: a contract manufacturer whose listed services include 3D printing, CNC machining and injection molding now owns electronics assembly and precision grinding shops that serve aerospace and defense customers.1
