Teradyne introduced its Optima 7300 post-reflow automated inspection system, the first in a series of next-generation machines. A single system can inspect the largest, highest-density boards while matching the line beat rate. For example, on a typical PC motherboard, the 7300 can inspect up to 250 units per hour including handling and diagnosis. The 7300 focuses on post reflow inspection, the optimal location to validate solder joint integrity and pre-screen boards before electrical test. The advantage of this strategy is to increase next-stage yield at in-circuit test and improve quality.
The system employs a patented configuration of vertical and angled cameras combined with a structured illumination system via a LED lighting system. It incorporates an image-acquisition system, which captures 10 images, each with a unique and dedicated lighting mode, for each field-of-view without impacting throughput or accuracy. Images from the TenPhase system is directly loaded into CPU memory, eliminating memory bus bottlenecks. By providing optimized lighting for each image the 7300 also significantly reduces false fail rates.
