PCB X-Ray Inspection Service for High-Reliability Electronics
Testing and inspection play a critical role in ensuring the accuracy, safety, and performance of modern electronics. As PCB designs become more compact and complex, traditional inspection methods are no longer sufficient to identify hidden defects. This is where PCB X-Ray Inspection Service becomes essential.
At Sierra Assembly, we provide advanced PCB X-Ray Inspection Service to help manufacturers detect internal defects that cannot be seen through visual or optical inspection. Our non-destructive testing approach ensures product reliability while maintaining board integrity, making it ideal for high-density and mission-critical applications.
What Is PCB X-Ray Inspection?
When imaging internal structures without causing damage to the board, PCB X-ray inspection Service (AXI) is a non-destructive testing technique that uses X-rays to see inside multilayer printed circuit boards (PCBs) and complex components.
This method ensures high quality for critical applications by revealing hidden defects like solder voids, shorts, misplaced parts, or internal cracks that visual inspection misses.
Why PCB X-Ray Inspection Is Important
As electronics manufacturing evolves, boards continue to shrink while component density increases. These changes make inspection more challenging and increase the risk of hidden assembly defects.
PCB X-Ray Inspection Service helps manufacturers:
-
Identify internal solder defects early
-
Validate assembly quality for complex designs
-
Reduce rework, scrap, and production delays
-
Improve long-term product reliability
For industries such as
aerospace, medical, automotive, and defense,
printed circuit board testing using X-ray inspection is no longer optional it is essential.
How PCB X-Ray Inspection Works?
Step 1: X-Ray Penetration Through PCB Layers
X-rays pass through the printed circuit board, where dense
materials such as solder and copper absorb more radiation, while lighter areas appear brighter. This contrast reveals hidden internal features.
Step 2: High-Resolution Image Creation
A detector captures the transmitted X-rays and converts them into detailed 2D or 3D images, clearly displaying solder joints, vias, BGAs, and internal component placement.
Step 3: Automated Defect Analysis
Advanced software analyzes the images to identify defects such as voids, shorts, cracked solder joints, and misaligned components. AI-based tools improve accuracy and repeatability.
Step 4: Reporting & Quality Verification
Inspection results are documented and reviewed against IPC and customer specifications, ensuring the PCB meets reliability and performance standards.

BGA and Solder Joint Inspection Capabilities
One of the most valuable applications of PCB X-Ray Inspection Service is bga x ray inspection. BGAs hide solder joints underneath the package, making them impossible to inspect visually. Our x ray solder joint inspection evaluates:
-
Ball alignment
-
Void percentage
-
Cracked or cold joints
-
Open BGA connections
This ensures reliable electrical performance in high-density
PCB designs.
X-Ray Weld Inspection in PCB Manufacturing
In electronics manufacturing, x ray weld inspection refers to the evaluation of solder “welds” or joints within PCB assemblies rather than metal fabrication welds. When used correctly in context, x ray weld inspection helps verify solder joint integrity, especially in power electronics and heavy copper designs.
At Sierra Assembly, x ray weld inspection supports internal quality validation during printed circuit board testing.
