A PCBA Tester is a critical quality assurance tool in SMT (Surface Mount Technology) manufacturing, designed to verify the electrical, functional, and structural integrity of assembled printed circuit boards (PCBAs). It employs ICT (In-Circuit Test) to detect short circuits and component defects, FCT (Functional Test) to simulate real-world operating conditions, and AOI (Automated Optical Inspection) to identify solder voids or misaligned components with micron-level precision. Advanced models integrate X-ray (AXI) for inspecting hidden solder joints (e.g., BGA, QFN) and Flying Probe Testers for high-density boards without custom fixtures. Compliant with IPC-A-610 and ISO 9001 standards, these testers ensure polarity correctness, solder joint reliability, and RoHS-compatible processes. Widely used in automotive and consumer electronics, PCBA testers support Industry 4.0 workflows through real-time diagnostics, predictive maintenance, and seamless integration with smart factory systems.
