Capability
Cable Assembly Quality Testing
Testing follows the wiring table, method, fixture, and pass/fail criteria. Depending on the assembly, MTTJ can perform continuity, polarity, hi-pot, insulation resistance, airtightness, visual, dimensional, label, and packing checks and record the agreed results.

What makes a test requirement usable
- Drawing or wiring table with continuity and polarity criteria
- Hi-pot, insulation, impedance, airtightness, or functional method with fixture, voltage, pressure, dwell time, and limits
- Visual, dimensional, label, packing, record format, and pass/fail criteria needed for shipment
Inspection
Checks available before shipment
Depending on the assembly, checks can cover continuity, polarity, hi-pot, insulation resistance, airtightness, appearance, dimensions, labels, and packing.
| Terminal crimping | Pull force, crimp height, terminal fit, wire gauge, and appearance are checked from the terminal model and matching wire specification. |
|---|---|
| Overmolding | Appearance, geometry, material, surface finish, sealing needs, and cable exit are checked from the drawing or 3D geometry. |
| Electrical testing | Continuity, polarity, hi-pot, insulation resistance, or functional test requirements are checked with the supplied method, fixture, and pass/fail limits. |
| Airtightness testing | Nitrogen test condition, pressure, and leak criteria supplied with the inquiry. |
| Ribbon cable processing | Splitting, tearing, cutting dimensions, appearance, and drawing-based pass/fail criteria. |
| Labeling and packing | Labels, markings, bagging, cartons, and shipment records follow the drawing, packing note, and order requirements. |

These images show where drawings, dimensions, connector details, materials, tests, and records affect the manufacturing step.
In‑house process
Electrical, visual, dimensional, packing checks
Each selected check is tied to the drawing, wiring table, test method, fixture, pass/fail limit, and record format used for the order.
- Continuity testing
- Polarity testing
- Hi-pot testing when specified
- Insulation resistance testing when specified
- Airtightness testing with nitrogen when specified
- Visual and dimensional inspection
Test setup
Values, fixtures, limits, records
Voltage, pressure, repetitions, functional sequence, sampling frequency, fixture, and pass/fail limits should be listed with the test method.
