Interconnect Solutions Company

What Interconnect Solutions Company does

Interconnect Solutions Company (ISC), legally ISC Engineering, LLC, is a California-based, vertically integrated contract manufacturer of custom interconnect and electromechanical solutions founded in 1971 and privately held by San Diego-based buyout firm Tide Rock since 2023. The company designs and builds high-reliability custom wire and cable assemblies, complex harnesses, electro-mechanical assemblies and box builds, printed circuit board assemblies (PCBA), and custom overmolded cable assemblies and encapsulated PCBs, with in-house mold tooling design and CAD/CAM capability and a library of more than 1,000 connector-to-cable overmold designs. Production is concentrated across three California facilities (Fountain Valley headquarters with cleanroom and dedicated program assembly labs; Santa Ana PCBA site acquired from MX Electronics in April 2023; Chino molded strain relief plant) and is supported by AS9100D aerospace certification, ISO 9001:2015, ITAR registration, IPC QML status, and IPC/WHMA-A-620 Classes 1, 2, and 3 trained operators.

ISC serves mission-critical OEMs in aerospace, military and defense, medical and life sciences, industrial, data centers and power infrastructure, and technology and communications, with named customers including Lockheed Martin, Northrop Grumman, BAE Systems, Moog, Harris Corporation, Anduril, Google, and Tesla. Use cases span defense platforms (RIwP, FBCB2, AARGM, GMLRS, JAGM, I-MILES VTESS, C-130 Aircrew Training Systems, Bradley Fighting Vehicles, ACV1.1, CV90, T50 Golden Eagle), aerospace galley hardware, medical diagnostic and imaging systems, EV charging cables and connectors, and overmolded assemblies for Google's Loon and other technology platforms.

The business model is project-based contract manufacturing on a high-mix, low-to-medium volume production profile, with quote-based pricing determined by project complexity, volume, and specification. Revenue is generated from hardware sales of custom assemblies and, to a lesser extent, professional services for mold tooling design and customer facility overmolding capability transfer. Go-to-market combines enterprise field sales with dedicated program management for major OEM accounts and inside-sales response via direct phone, online RFQ submission, and NDA execution, with a stated 24-hour response time on project inquiries. Leadership transitioned in May 2023 when Tide Rock appointed Nick Kendall-Jones (formerly President of a $1B+ segment at Ingersoll-Rand) as CEO, with predecessor Michael Engler moving to lead portfolio sister company Plastic Molding Technology (PMT).
