PCB Insider builds aircraft wire harness assemblies for aerospace teams that need more than manual assembly capacity. We support prototype, qualification, and production programs with controlled documentation, repeatable process flow, and 100% electrical test coverage.
If you are evaluating aircraft wire harness manufacturers, the practical question is whether the supplier can control routing, shielding, connector systems, installation geometry, and test records at the same time. That is the gap this page is designed to address.

100%
Electrical Verification Coverage
Aircraft harness programs usually fail at the interface between electrical intent and installation reality. A harness can pass a bench continuity test and still become a program problem if bend radius, branch breakout geometry, shield termination, or clamp location were not considered early enough.
Aerospace buyers therefore look beyond simple assembly labor. They need suppliers who can manage workmanship to IPC/WHMA-A-620-related standards while also understanding documentation flow, environmental expectations, and release discipline often associated with AS9100-oriented aerospace quality systems.
Environmental requirements matter as well. Aircraft and aerospace electrical assemblies are often reviewed against vibration, temperature, and EMC expectations influenced by guidance such as RTCA DO-160 and airworthiness frameworks administered by the Federal Aviation Administration. We do not position ourselves as the design authority for your aircraft, but we do build with those downstream realities in mind.

Aerospace programs lose time when fixture expectations and acceptance logic are left until after the first article build. We prefer to frame the electrical verification plan while the release package is still being stabilized.
Aircraft harness manufacturing works best when each phase has a clear release gate. That matters most when the same supplier is expected to support early engineering learning and later production stability.

Reduce avoidable routing, connector, and documentation issues before tooling starts.
The best starting package includes harness drawings, connector and contact callouts, wire list, branch lengths, shielding requirements, installation constraints, test requirements, and target annual demand. If the design is still early, a schematic plus installation photos or CAD screenshots is enough for a manufacturability review and budgetary quote.
Yes. We support prototype harnesses for fit and function checks, qualification lots with documented test coverage, and repeat production once the released configuration is stable. The same controlled work instructions and revision discipline used during sampling carry into production to reduce drift.
Most aircraft harness programs require 100% continuity and short-circuit testing as a baseline. Depending on the application, we also perform insulation resistance, dielectric withstand, pull-force verification, dimensional inspection, shielding continuity checks, connector retention checks, and customer-defined functional testing.
No. We support harnesses for manned aircraft, helicopters, eVTOL subsystems, UAV payloads, ground-support electronics, and aerospace test equipment. The exact construction depends on temperature, vibration, routing geometry, weight targets, and documentation requirements.
We review branch breakout geometry, connector orientation, bend radius, shielding termination, service loops, clamp points, and installation sequence before release. That front-end review matters because an electrically correct harness can still fail the program if it is difficult to route or maintain inside the real assembly.
