Product Specifications

Technical details and manufacturing context for Signal Switching Matrix

Definition
A critical component within Test Head/Controller systems that enables automated routing of electrical signals between test instruments (sources) and device-under-test (DUT) interfaces. It provides configurable signal paths for testing multiple parameters or devices without manual reconnection, essential for high-throughput automated testing in electronics manufacturing.
Working Principle
Uses solid-state relays, electromechanical relays, or semiconductor switches to create programmable signal paths. A control system (often integrated with the test controller) configures switch states to connect specific source channels to target DUT pins based on test requirements, enabling sequential or parallel testing of multiple signal lines.
