Analysis of the implementation of the optical inspection process

The aim of the work presented was to analyze and present the case study of the change in electronic board testing technology from in-circuit testing to optical inspection, with a focus on improving the quality index of products at Intelbras S/A. In order to make this work possible, the methods of visual inspection, in-circuit tester (ICT), and Automated Optical Inspection (AOI) were described. The Automatic Insertion (SMT) and Wireless Telephone Assembly sectors within Intelbras S/A were presented. Finally, the study that led the company to change its testing method from in-circuit testing to optical inspection was described. The work presented proved to be effective, proving that the optical inspection machines presented a higher quality guarantee than the in-circuit tests, detecting defects that would not have been detected with the previous method.
