Vision Inspection has introduced the AOI systems Vi-1000 and Vi-3200. Model Vi-1000 verifies component presence or absence and polarity on board assemblies at speeds of up to 200,000 components per hour. Vi-3200 has been designedfor the inspection of largerboards of up to 600 x 600mm with a throughput of up to 150,000 components per hour. It is capable of verifying component positioning (X, Y and theta), polarity, text, presence/absence, and can inspect solder paste and joints anddetect bridges. Both sys-tems employ maintenance-free linear motors and glass-scale optical encoders to ensure precise closed-loop positioning. Accuracy is within 61µm, repeatability is ±5µm (6-Sigma) at speed of up to 2m/s. The systems can reportedly be programmed in less than 15 minutes using Gerber, CAD or ASCII/centroid supplied data.
