Cable Assembly

ICT Testing Service

ICT testing is where many cable assembly RFQs stop being theoretical and start becoming production-ready. We review your drawing, BOM, net list, fixture logic, pass/fail limits, and documentation burden before quote so buyers know exactly how continuity, resistance, hipot, insulation checks, and traceability will be controlled before shipment.

Application Context

What an ICT testing service actually verifies

ICT (in-circuit / electrical) testing is where a cable assembly RFQ stops being theoretical and becomes production-ready. Rather than pricing test as a vague add-on, engineering reviews your net list, connector orientation, expected resistance limits, fixture interface, and failure-report expectations before quotation, so the test scope is aligned to the real assembly risk. The baseline is 100% continuity and miswire detection — opens, shorts, swapped circuits and polarity — with resistance windows, insulation resistance, and hipot added only where voltage class, sealing risk, or customer compliance require it. The point is to match test burden to buyer risk, not to run theater. Where a program needs a dedicated end-of-line test station, we can align this with a wire harness tester program built around the same net list and pass/fail logic.

Test scope scales with the application. Multi-branch industrial and control harnesses rely on continuity and miswire detection to catch connector mix-ups before machine build, while high-voltage cable assemblies add hipot and insulation-resistance windows for objective dielectric release evidence. Whichever level applies, the output is not just a pass light on the tester — it is a release package with lot summary or unit-level records, revision-linked test history, and a certificate of conformance on request that receiving, quality, and program teams can actually use.

Service Scope

ICT Testing Service Scope

Built for buyers who need clear pass/fail logic before they release production quantities

Net List, Pin Map, and Fixture Review Before Quote

We do not price ICT as a vague add-on. Engineering reviews your net list, connector orientation, expected resistance limits, fixture interface, and failure-report expectations before quotation so the test scope is aligned to the real assembly risk.

  • Drawing, BOM, and test spec review
  • Fixture-point and adapter planning
  • Pass/fail logic defined before sampling

Continuity, Resistance, Hipot, and Insulation Options

ICT programs can include continuity and miswire detection as the baseline, then add resistance windows, insulation resistance, or hipot where voltage class, sealing risk, or customer compliance requires it. The point is to match test burden to buyer risk, not to run theater.

  • Open, short, and swap detection
  • Resistance windows when required
  • Hipot and insulation checks by specification

Documented Release Records for Receiving and Audit Teams

If your customer receiving team, OEM quality group, or regulated project needs proof, we can align the release package to lot traveler, unit record, fixture ID, revision, and certificate needs before production starts.

  • Lot summary or unit-level records
  • Revision-linked test history
  • Certificate of conformance on request

Engineering Challenges

What we review before quoting

01

Undefined Test Scope

The cost of an undefined test plan usually appears after the PO is released. We quote against fixture effort, record depth, and acceptance criteria instead of hiding test cost inside a generic production line item.

02

Net List & Pin-Map Ambiguity

Missing net-list logic, connector orientation, and expected resistance limits are flagged before the first sample, so buyers compare suppliers on the same scope rather than on assumptions.

03

Fixture Interface & Access

Fixture points, adapters, and test-point access are planned up front — because a pass/fail result is only as reliable as the fixture and interface behind it.

04

Documentation & Traceability Depth

Lot traveler, unit record, fixture ID, revision, and certificate needs are aligned before production starts so audit and receiving teams get the evidence they actually require.

Quality & Testing

Documented electrical verification for buyer release

Every ICT program can combine 100% continuity and miswire detection with optional resistance windows, insulation resistance, and hipot by specification — each result captured in a lot summary, unit record, or certificate of conformance so receiving, quality, and program teams have objective release evidence before shipment.

Why WHP

Why Buyers Source ICT Testing From WellPCB

Because the cost of an undefined test plan usually appears after the PO is released

Problem-Aware Quotation

We quote against fixture effort, record depth, and acceptance criteria instead of hiding test cost inside a generic production line item.

Engineering Review Before Sampling

Missing net-list logic, connector ambiguity, and report expectations are flagged before the first sample so buyers compare suppliers on the same scope.

Risk-Based Test Planning

Not every harness needs the same burden. We match ICT, resistance, and dielectric checks to voltage class, installation consequence, and buyer documentation needs.

Procurement-Ready Release Records

The output is not just a pass light on the tester. It is a release package your receiving, quality, and program teams can actually use.

FAQ

Buyer Questions Before RFQ

What should I send to quote an ICT testing service accurately?
Send the drawing, BOM, net list, quantity, revision level, and the report package your team expects at shipment. If resistance windows, hipot, insulation resistance, or customer-specific fixture logic are required, include those rules in the first RFQ.
Can you support prototype builds before recurring production?
Yes. We can define the ICT logic during sample builds, validate the fixture approach, and then carry the approved matrix into pilot and recurring production once the release package is locked.

OEM Program Entry

Scenario

During a pre-production sample run, a temporary material shortage threatens the delivery schedule.

Challenge

Specific tape and wire-color materials are temporarily unavailable, risking delays for the sample run, while the customer still needs the samples urgently and holds strict specifications for the final product.

Solution

We propose temporary material substitutions for the sample run only, clearly document the deviation, secure engineering approval, and commit to sourcing the exact original materials for mass production.

Result

Sample production proceeds on schedule, the customer accepts the documented deviations for samples, and production batches adhere to the original specifications.

Sample run delivered on scheduleDeviation documented and engineering-approvedProduction held to original specifications
