The Test Research Inc. TR7550 is a piece of laboratory equipment — specifically an Automated Optical Inspection system, sometimes referred to as an AOI machine — used in electronics manufacturing for the high-speed inline inspection of printed circuit boards. Test Research Inc., commonly known as TRI, is a recognised manufacturer of automated inspection and testing equipment serving the PCB assembly and electronics production industries.
This unit dates from 2011 and is offered in used condition. According to the seller's notes, the TR7550 was introduced around 2010 and is designed for inline AOI inspection both before and after reflow soldering processes. The system employs a top-view 3-CCD colour camera working in combination with four angled cameras to maximise test coverage across the board surface. TRI's dynamic imaging technology is incorporated to minimise vibration during operation and deliver stable, accurate results at production-line speeds.
The optical arrangement is supported by an advanced RGB plus white lighting system, which is designed to enhance the detection of solder joints and component markings. A linear motor X-Y table drives the inspection head, providing vibration-free movement and contributing to the precision of the imaging process. The 3-CCD camera configuration is stated to be capable of resolving 01005 fine-pitch components, which represent some of the smallest passive components used in surface-mount assembly.
The range of detectable defects is extensive. The system is noted to identify missing components, tombstoning, billboarding, polarity errors, rotation and shift faults, wrong marking via optical character verification, defective components, upside-down placement, lifted components, solder excess, insufficient solder, bridging, through-hole pin issues, lifted leads, and golden finger scratches or contamination. This breadth of fault coverage makes the TR7550 suitable for comprehensive quality control across a wide variety of PCB assembly processes.
