AUTOMATIC VISION FOR HYBRID CIRCUIT QC AND INSPECTION.

Machine vision inspection is becoming widely accepted in the manufacture of hybrid circuits. With increasing circuit densities and larger substrate sizes, the need for automatic optical inspection (AOI) is obviously apparent. With larger substrates and smaller traces, inspectors must take a longer time to inspect and there is a greater probability of missing a defect. AOI can reduce production costs, enhance reliability and provide better process control through repeatable, consistent inspection criteria. All hybrid circuit manufacturers can justify some type of AOI. But those with moderate to high volume production and those producing low volume, high reliability circuits should not be without it.
