Cable Assembly
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 windows, and traceability will be controlled before shipment. Hi-pot and insulation resistance, when required, are coordinated through a qualified third party.
Application Context
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 circuit-resistance windows added where the application requires it. Insulation resistance and hi-pot (dielectric withstand) are not run in-house; when voltage class, sealing risk, or customer compliance require them, we coordinate them through a qualified third party. 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 need hipot and insulation-resistance testing, which we coordinate through a qualified third party 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
Built for buyers who need clear pass/fail logic before they release production quantities
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.
ICT programs include continuity and miswire detection as the baseline, then add circuit-resistance windows where the application requires it. Insulation resistance and hi-pot are not run in-house; where voltage class, sealing risk, or customer compliance requires them, we coordinate them through a qualified third party. The point is to match test burden to buyer risk, not to run theater.
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.
Engineering Challenges
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.
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.
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.
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.
Technical Capabilities
Electrical verification matched to buyer risk — continuity and miswire detection as the baseline, with circuit-resistance windows by specification; insulation resistance and hi-pot coordinated through a qualified third party.
Manufacturing Process
Quality & Testing
Every ICT program can combine 100% continuity and miswire detection with optional circuit-resistance windows by specification; insulation resistance and hi-pot are coordinated through a qualified third party when required — 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
Because 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.
Missing net-list logic, connector ambiguity, and report expectations are flagged before the first sample so buyers compare suppliers on the same scope.
Not every harness needs the same burden. We match ICT and resistance checks to voltage class (dielectric checks coordinated through a qualified third party), installation consequence, and buyer documentation needs.
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.

RFQ Checklist

automotive
During a pre-production sample run, a temporary material shortage threatens the delivery schedule.
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.
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.
Sample production proceeds on schedule, the customer accepts the documented deviations for samples, and production batches adhere to the original specifications.
