How PCB X-Ray Inspection Works
PCB X-Ray Inspection uses high-resolution X-rays to examine hidden internal structures and solder joints inside electronic assemblies. Dense materials such as solder absorb more X-rays and appear darker in the inspection image, while lighter materials appear more transparent.
This process allows engineers to detect hidden defects such as:
-
Open circuits
-
Solder voids
-
Shorts and bridges
-
Misaligned components
-
Cracked or insufficient solder joints
-
BGA connection issues
PCB X-Ray Inspection is especially critical for BGA assemblies, multilayer PCBs, and high-density electronic components where defects cannot be identified through standard visual inspection.
Key Benefits of PCB X-Ray Inspection
Internal Defect Detection
PCB X-Ray Inspection identifies hidden defects such as solder voids, internal cracks, open connections, and multilayer PCB issues that are not visible from the surface.
Comprehensive PCB Analysis
X-ray imaging provides a detailed internal view of PCB assemblies, helping manufacturers verify solder joint integrity, component alignment, and overall assembly quality.
High-Precision Inspection
Advanced X-ray inspection delivers accurate defect detection for BGA assemblies, fine-pitch components, and high-density PCB applications where reliability is critical.
Reduced Rework and Production Risk
By detecting hidden defects early, manufacturers can reduce rework, minimize scrap, avoid production delays, and improve overall product quality.
