Sam's Electronic Technologies in Chula Vista holds AS9100 certification and operates as both an FAA- and EASA-authorized repair station from its Colorado Avenue facility, manufacturing wire cable harnesses for military and commercial aerospace clients since 1973. Build-to-print fabrication runs span prototype through full-production volumes using MIL-spec wiring and connectors, a supply chain overlapping with the electrical-component inventory at California Electric Supply in the same South Bay industrial corridor. The woman-owned firm covers NAICS codes 335929, 335931, and 335999, placing it across communication-wire assembly, current-carrying wiring-device manufacturing, and miscellaneous electrical-component production. Cable-harness assemblies undergo continuity testing, hi-pot dielectric verification, and visual inspection per IPC/WHMA-A-620 workmanship standards before shipment to defense and aviation OEMs, a quality regime distinct from the consumer-electronics servicing at Intertronix nearby. Highest-tier production encompasses multi-conductor shielded harnesses assembled to IPC/WHMA-A-620 Class 3 workmanship criteria for mission-critical avionics and defense-platform integration.
