Machine vision inspection of solder paste on PCB’s is a non-trivial
task. In this paper we describe a smart machine vision
(SMV) system for inspecting defects of solder paste on
PCB’s. SMV was developed using machine learning
technology combined with advanced machine vision
techniques. SMV has been deployed on a
manufacturing line and been tested on more than 2000
PCB boards, the accuracy of detection has exceeded
97%.
