A PCBA Test Rack Fixture is a specialized tool used to secure and electrically interface with Printed Circuit Board Assemblies (PCBAs) during functional testing (FCT), in-circuit testing (ICT), or burn-in validation. Designed for durability and precision, it features anti-static materials (e.g., FR4, aluminum) and customizable test points (50–2000+) to accommodate high-density boards, IoT modules, or automotive control units. Advanced fixtures integrate spring probes or pogo pins for reliable contact, programmable voltage/current ranges (3–600V DC), and compatibility with automated test equipment (ATE) via USB/Ethernet. Widely used in electronics manufacturing, aerospace, and automotive industries, these fixtures ensure compliance with ISO 17025 and IPC-A-610 standards while reducing false failures and improving throughput. Their modular design supports rapid reconfiguration for multi-product lines and harsh-environment testing (IP54-rated), making them essential for quality assurance in high-mix, high-volume production.
