Research of the PCB Quality Detection for IC Mount Base on the Digital Image Recognition

Abstract:

A detection method is given in this paper for the automatic surface solder printing quality detection during the automatic welding on PCB. The method of variable metric is used in the processing of the target positioning and the target recognition is used based on the machine vision. The method given here can greatly improve the processing speed in real. The processing of the rotating angle axis positioning theory is mentioned and the verification is done by experiment. This method has the advantage of high accuracy, small detection error and easy to operate.
