X Ray Inspection for SMT: Detecting Hidden Issues in Surface Mount Technology

SMT x-ray inspection detects hidden defects in surface mount assemblies, such as solder voids, bridging, head-in-pillow, and component placement errors in BGAs and QFNs. It provides subsurface analysis beyond AOI limits. This guide covers technical principles, 2D and 3D systems, solder paste inspection, best practices, troubleshooting, and FAQs for electric engineers optimizing PCB quality control.
