Improved Efficiency of in-line THT PCB Inspection

GOEPEL introduces the new OptiCon THT-Line - a dedicated in-line inspection system for the test of large through-hole technology (THT) components.

The system can be utilized in the production process either for manual loading or for inline integration into an accumulation roller conveyor system. During the inspection process PCBs can remain in the production specific carrier. Depending on production organisation, carriers with or without assemblies can be returned in the lower part of the AOI system.


The software package OptiCon PILOT controls test program generation as well as assembly inspection. For efficient use of the system, repair station software, statistical fault evaluation andoffline programming software modules are available. Flexible data interfaces provide the opportunity to communicate with external MES and quality management systems. The OptiCon THT-Line features the latest system software version OptiCon PILOT 5.2. It supports the inspection of THT assemblies by particularly convenient opportunities for test program generation by means of “easyELKO” and “easyOCR”. These functions allow for polarity check of electrolytic capacitors as well as label reading without prior pre-learning process. Compared to already known character recognition methods, this means a revolutionary step in OCR utilization for quality control of electronic assemblies.
