X-Ray PCB Inspection Services

Topline Circuit uses X-ray inspection to examine hidden solder joints beneath ball grid array (BGA) packages. This process helps identify defects such as voids, solder bridges, insufficient solder, and misaligned connections between the solder balls and PCB pads. X-ray inspection is part of our quality control process for verifying BGA assembly quality.

Overview of X-Ray PCB Inspection Services

Topline Circuit uses X-ray inspection to evaluate hidden solder joints and internal assembly connections that cannot be checked through visual inspection alone.

The process provides consistent inspection results and helps detect voids, solder bridges, open connections, misalignment, and other assembly defects.

AOI vs. X-Ray PCB Inspection

Automated optical inspection (AOI) uses cameras to examine visible solder joints, component placement, polarity, alignment, and surface defects. It checks the assembled board against defined inspection criteria.

X-ray inspection examines solder joints and connections hidden beneath components, including BGA, QFN, and other bottom-terminated packages. It is used to detect internal defects that AOI cannot see, such as voids, solder bridges, open joints, and insufficient solder.

X-Ray PCB Inspection Applications

X-ray inspection is used for PCB assemblies with hidden solder joints, high-density components, or demanding quality requirements. Common applications include:

Telecommunications equipment
Aerospace systems
RF and microwave devices
Military and defense electronics
Medical devices
Automotive electronics
Consumer electronics
Industrial control equipment
Energy systems
