1 HARDWARE STRUCTURE AND BASIC PRINCIPLES
TR7600 SIII in-line Automated X-ray Inspection system uses X-ray technology to inspect
PCBAs and components. This system is ideal for inspecting BGA components and areas not
accessible by other test technology. Currently, the system could use 7µm, 10 µm, 15 µm and
20 µm resolution to perform inspection.
TRI proprietary image evaluation technology appraises the dark and light areas, separates
the different image slices and calculates the different slice heights during inspection.
Inspection result can be sent to Repair Station for analysis and follow up action.
1.1 Hardware Structure
Refer to the Figure below. At the top of the system is X–ray source. It is moved by X-Y-Z
table system. At the center, the PCBA panel is transferred by conveyor and fixed by the step
motor and mechanism; at the bottom are cameras. The camera system is moved by X-Y-Z
table system in sync with the X–ray source. Images can be captured using nine different
angles.

1.2 Basic Principles
Refer to the Figure below. The six-axis system is able to capture images using different
resolutions and angles. The machine could capture nine images with different angles,
separate the overlapping top and bottom images and combine all images to become one
image as you see on the screen.

1.3 TRI Application
Basic Automatic X-Ray Inspection will be conducted with the following 3 applications.
1) TR7600: AXI main software where major PCB inspections are programmed and
conducted
2) TRI AXI InsertData: Transport and categorize the files into designated folders.
3) TRI AXI RS: Repair Station main software where user can confirm the defects and
retrieve the inspection data here.
