It fits first time
A unit that needs shimming on a flight line is a failed unit. Mechanical fit and connector alignment are verified on the assembly, not assumed from the parts.
Line ReplaceableUnits
Final assembly of sealed enclosures, chassis and control units. Built to a revision controlled package, tested as a finished unit, serialized, and shipped ready to install rather than ready to inspect.

Overview
Built to be swappednot repaired
A line replaceable unit is a box a technician swaps in the field without opening it. That single fact sets every requirement behind it. It has to fit the first time, work the first time, and be identical to the one that came before it.
Which is why final assembly is where the rest of what our team does converges. The cards, the harnesses, the machined housing, the fabricated enclosure and the pack inside it are all commodities our team already quotes. Here they arrive as one finished unit, against one purchase order, with one company accountable for whether it works.
The standard
What a field swapactually demands
Nobody troubleshoots an LRU in the field. They pull it and fit another one. Everything about how the unit is built follows from that.
Configuration control
Built to a released and revision controlled package. When the drawing changes, the build changes with it and the change is recorded.
Tested as a unit
Subassemblies passing individually does not mean the box works. Functional test runs on the finished unit against your acceptance procedure.
Traceable afterwards
Serialized, with component lot traceability and an as built record, so a failure two years out can be traced to what went into it.
Process
From data packageto sealed unit
Data package review
Assembly drawings, wiring diagrams, parts list and the acceptance test procedure. Our team flags what is missing or contradictory before the first unit is built, not during it.
Kitting and configuration
Every component pulled to the released revision, kitted by serial, and held under configuration control for the duration of the build.
Mechanical build
Housings, brackets, gaskets and thermal interfaces assembled to the drawing, with torque values recorded where the print calls for them.
Electrical integration
Circuit cards mounted, harnesses routed and terminated, connectors installed and backshells torqued to IPC-A-610 and IPC/WHMA-A-620 workmanship.
Sealing and protection
Conformal coat, potting, gasketing and environmental sealing where the unit has to survive weather, vibration or wash down.
Functional test and ship
Test to your acceptance procedure, serialize, record the results, and pack so the unit arrives ready to install rather than ready to inspect. Full ESS, shock and vibe testing to Mil spec standards.

Assembly drawings, a parts list and the acceptance test procedure is enough to start. Our team will tell you what it costs and what the drawing is missing.
