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.

Buyer questions this capability answers

  • Which electrical checks are required?
  • Is a functional test procedure provided?
  • What visual inspection criteria should be used?
  • What documentation or shipment records are required?

RFQ requirements

  • Drawing and specifications
  • Continuity and polarity requirements
  • 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

Process

How the requirement moves through review

These steps show the normal review path from customer input to production release, inspection, packaging, and shipment preparation.

  1. 1

    Incoming inspection

  2. 2

    Qualified material storage

  3. 3

    Production planning

  4. 4

    Wire processing / assembly / molding

  5. 5

    In-process inspection

  6. 6

    Electrical and project-defined testing

  7. 7

    Final inspection

  8. 8

    Packaging and export delivery review
