Test Reasearch Inc TR7550 AOI Systems

The Test Research Inc. (TRI) TR7550, introduced around 2010, is an Automated Optical Inspection (AOI) system designed for high-speed, inline inspection of printed circuit boards (PCBs) in electronics manufacturing. It utilizes a top-view 3-CCD color camera and four angled cameras to optimize test coverage, employing TRIs dynamic imaging technology to minimize vibrations and provide accurate, stable inspections before and after reflow soldering processes.

Key features of the TR7550 include:

- High-Speed Inline Color AOI: Ensures comprehensive inspection coverage.
- Precise 3-CCD Color Camera: Capable of inspecting 01005 fine-pitch components.
- Advanced RGB+W Lighting System: Enhances detection of solder and markings.
- Linear Motor X-Y Table: Provides vibration-free, accurate inspection.

The system is suitable for inspecting various component defects such as missing components, tombstoning, billboarding, polarity issues, rotation, shift, wrong marking (OCV), defective components, upside-down placement, lifted components, solder excess, insufficient solder, bridging, through-hole pins, lifted leads, and golden finger scratches or contamination.
