Cable Assembly
Custom MIL-SPEC wire harness assemblies built to MIL-DTL-32862, MIL-W-22759, and NASM standards. Rugged construction for defense, aerospace, and mission-critical applications. ISO 9001 certified with full material traceability.
Application Context
When your wire harness is going into an armored vehicle traversing desert terrain, a fighter jet pulling 9G turns, or a submarine operating at crush depth, there is zero margin for error. Military-specification wire harnesses demand a level of material control, process discipline, and testing rigor that separates qualified manufacturers from commercial cable shops.
WellPCB manufactures custom mil-spec wire harness assemblies for defense prime contractors, aerospace integrators, and government agencies who require full compliance with MIL-DTL-32862, MIL-W-22759, and related military standards. Every wire is QPL-listed. Every crimp is force-monitored. Every harness is individually tested and serialized. We do not batch sample — we verify every single unit.
From initial prototypes for engineering development models to full-rate production supporting active defense programs, we deliver complete documentation packages including First Article Inspection Reports per AS9102, certificates of conformance, and individual test data. Our quality system is aligned to AS9100D requirements, giving defense procurement teams confidence in our process control and traceability.
Applications
End-to-end military-grade wire harness manufacturing from material procurement through qualification testing.
Wire harness assemblies manufactured per MIL-DTL-32862 requirements. Each harness undergoes qualification testing including thermal shock, vibration, and salt fog.
Precision processing of PTFE, polyimide, ETFE, and cross-linked ETFE insulated wire per MIL-W-22759. Automated cut-strip-crimp with force monitoring on every termination.
Ruggedized construction with environmental backshells, heat shrink boots, and potting compounds. IP67/IP68 sealed connectors withstand immersion, sand, and dust.
Braided and foil shielding architectures exceeding 90 dB attenuation. Grounding and bonding per MIL-STD-464 electromagnetic environmental effects requirements.
QPL-listed wire, connectors, and hardware with certificates of conformance. Lot traceability from raw material through final acceptance per MIL-STD-790.
Complete First Article Inspection Reports (FAIR) per AS9102. PPAP documentation packages for defense prime contractors. Configuration management per MIL-STD-973.
Engineering Challenges
Sourcing QPL-listed wire, connectors and hardware with certificates of conformance, and controlling lot traceability from raw material through final acceptance per MIL-STD-790.
Ruggedized construction, environmental sealing and potting validated to MIL-STD-810 for thermal shock, vibration, salt fog, altitude and immersion.
Braided and foil shielding architectures exceeding 90 dB attenuation, with grounding and bonding per MIL-STD-464 electromagnetic environmental effects requirements.
100% electrical test, First Article Inspection per AS9102, and PPAP-ready documentation packages for defense prime contractors.
Technical Capabilities
Performance parameters for our mil-spec wire harness assemblies, built to ISO 9001:2015 with AS9100D-ready supply chain and IPC/WHMA-A-620 Class 3 workmanship.
Manufacturing Process
Quality & Testing
Every mil-spec harness is individually tested and serialized — 100% continuity verification, dielectric withstand (hi-pot) per MIL-STD-202, and insulation resistance — with crimp force monitoring and a complete documentation package (FAIR per AS9102, certificates of conformance, and lot traceability per MIL-STD-790) before it ships. No batch sampling.

In military wire harness manufacturing, there are no acceptable defects. Every crimp, every solder joint, every wire route is a potential point of failure in a system where lives depend on reliability. That's why we test every harness individually and trace every material back to its source — because mission readiness starts on the production floor.
