About JEM Electronics, Inc.
JEM Electronics, Inc. was founded in 1981 by John McDonald in Franklin, Massachusetts. Today JEM operates from its headquarters in Franklin, MA, and a production facility in Tijuana, Mexico, providing build-to-print manufacturing from prototype through high-volume production. Core capabilities include custom cable assembly, complex wire harness assembly, and integrated box-build electromechanical assembly. Every assembly undergoes 100% in-house testing—continuity, pull, hipot, and VSWR—under documented procedures aligned with IPC/WHMA-A-620 workmanship standards. The company employs cross-trained assemblers and applies Lean Six Sigma methods to maintain process consistency. JEM serves OEMs in regulated, high-reliability sectors including military and defense, medical, semiconductor, robotics, renewable energy, oil and gas, and networking. Its ITAR registration and CAGE code 3DTF7 support defense and government contract work, while ISO 9001:2015 and UL/CSA certifications cover commercial and industrial requirements. The company differentiates itself by reviewing every drawing for manufacturability before quoting, delivering transparent timelines, and standing behind each assembly with full traceability documentation. McDonald’s original vision—to solve customer problems through modern technology and repeatable quality—remains the guiding principle behind JEM’s disciplined, documented process from drawing to delivery.
