Capability
Cable Assembly Testing and Quality Control
Testing and inspection expectations should be defined during RFQ so production teams can align drawings, materials, assembly steps, acceptance criteria, documentation, and packaging.

- Hi-pot, insulation, impedance, airtightness, or functional test procedure if applicable
- Visual inspection criteria
- Documentation requirements
- Packaging and shipment requirements
Control points
What must be defined before production release
Control points must be defined from the drawing, material, connector, test method, and acceptance criteria for the specific project.
| Terminal crimping | Pull force, crimp height, and appearance; customers provide terminal model and matching wire specification. |
|---|---|
| Overmolding | Appearance, geometry, material, sealing needs, and cable exit; customers provide drawing or 3D geometry. |
| Electrical testing | Continuity, hi-pot, insulation resistance, or functional test requirements defined by drawing. |
| Airtightness testing | Nitrogen test condition, pressure, and leak criteria supplied by the customer. |
| Ribbon cable processing | Splitting, tearing, cutting dimensions, appearance, and drawing-defined acceptance criteria. |
In-house scope
Manufacturing steps MTTJ can review
Exact process scope depends on the drawing, material, connector, and testing requirements supplied during RFQ.
- Continuity testing
- Polarity testing
- Hi-pot testing when specified
- Insulation resistance testing when specified
- Airtightness testing with nitrogen when specified
- Visual and dimensional inspection
Boundary
Partner sourcing or engineering review
Partner sourcing or additional engineering review is identified during RFQ when a requirement sits outside the ordinary in-house process path.
- Horizontally injection-molded housings requiring horizontal molding machines
- PCB assemblies / circuit boards
- Project-specific certified components or plug assemblies supplied through qualified sources
