X-Ray PCB Inspection Services

DFYC uses X-ray inspection technology to check solder defects and inspect the connection between BGA balls and PCB pads. This helps us find hidden assembly issues that cannot be seen from the surface. X-ray inspection is also part of our PCB assembly quality control process, helping us improve product reliability and meet customer quality requirements.
Overview of DFYC’s X-Ray PCB Inspection Services
DFYC uses advanced 3D X-ray inspection technology to check PCB assemblies with speed, accuracy, and consistency. This inspection process helps detect hidden solder defects, BGA connection issues, and voids that are difficult to see from the surface. With reliable X-ray PCB inspection, we support better quality control and help improve the reliability of each assembled board.

AOI vs. X-Ray PCB Inspection
AOI checks the surface of a PCB assembly from above. It helps inspect solder joint quality, component placement, polarity, and visible assembly defects. X-ray PCB inspection is used to check hidden solder defects and internal connections, especially under BGA, QFN, and other bottom-terminated components.
Applications for X-Ray PCB Inspection
X-ray inspection is commonly used in PCB and PCBA projects across a wide range of industries, including:
- Industrial Control
- Electric Vehicles (EV)
- Communication Equipment
- Optical Modules
- Servers and AI Servers
- Medical Electronics
- Consumer Electronics
- Smart IoT Devices
- Power Management Systems
- Embedded Computing Platforms
