Easy to use OCR for electronic Components

01 July 2011 — GOPEL electronic’s OptiCon AOI systems continue to enhance their wide toolset with the introduction of the unique easyOCR tool, which revolutionises the utilisation of optical character recognition (OCR), achieving significant time savings in the generation of AOI test programs.

Up to now, OCR functions were accompanied by circumstantial learning of single characters, frequently resulting in extended programming and debug time. Utilising easyOCR this situation is now a thing of the past.

easyOCR  only requires the programmer to define a test step is define the area around the text to be read and the expected text. Because of an additionally integrated intelligence, a selective text comparison in combination with alternative defaults can be executed after the reading process.  Based on a comprehensive data base as well as a fault tolerant text reading algorithm, all prints of various alphanumeric characters can be safely read and provided a character strings. This function is provided as library entree for the automatic test program generation based on placement data. In addition to a highly simple operation, the function is characterised by a low false call rate.

easyOCR  is available in all OptiCon AOI systems. GOEPEL electronic’s AOI systems can be applied as inline and offline versions for SMD and THT components before and after the soldering process. Depending on system version and configuration, additionally the top and bottom inspection of double-sided PCBs in just one system is also possible.
