In-circuit testing uses electrical access to check selected components and connections on an assembled PCB. Bed-of-nails fixtures provide contact with multiple test points, supporting repeatable checks in production where the board design permits suitable access.
ICT can identify faults such as certain component-value errors, opens and shorts within its coverage. Functional testing serves a different purpose by exercising the board or product under defined operating conditions. A fixture may support either approach or a combined sequence, depending on the test system and application.
Board access, fixture design and test development should be considered early. Test-point spacing, component clearance and contact reliability affect performance. Compare coverage, cycle time and fixture maintenance against the production volume. Clear pass/fail limits and recorded results help operators investigate faults and keep board-level test history.
