Testing

ICT and functional test catch different PCB assembly failures. Learn when each test pays for itself and how to specify test coverage.

Crimp pull testing is one of the fastest ways to check whether a wire-to-terminal termination has real mechanical margin or only looks acceptable. This guide explains what pull testing proves, what it does not prove, and what buyers should define before approving a wire harness build.

Continuity-only testing is not enough for many wire harness and cable assembly programs. This guide explains what continuity, insulation resistance, and hipot testing each prove, what buyers should specify in the RFQ, and what records a supplier should retain before release.

Burn-in testing can be a useful screen for early-life failures in PCB assembly and box build work, but only when the load, temperature, duration, and records are clearly defined. This guide explains when buyers should ask for burn-in, what it can actually prove, and when other test methods are more effective.
