SEHO Systems GmbH, a worldwide leading manufacturer of automated soldering systems and customer-specific solutions, will highlight the new AOI function for its best-selling selective soldering system – the PowerSelective - in Booth #3521 at the upcoming IPC APEX Expo, scheduled to take place February 28 - March 1, 2012 at the San Diego Convention Center in California.
SEHO has developed an automated optical inspection (AOI) system that can be embedded directly in the selective soldering process. The system is used for the detection of soldering defects such as non-wetting or insufficient wetting, missing pin or bridging. The inspection begins immediately after the soldering process when the printed circuit board is fixed in the gripper of the soldering machine.
The AOI system can be easily integrated into a SEHO PowerSelective, offering remarkable cost savings in floor space and board handling equipment. Depending on the complexity of the products to be soldered, the AOI system can be activated if solder joints are considered to be critical, or it may be deactivated for uncomplicated boards, thus reducing overall production time. While using the AOI system in the production process, the unit allows separation of assemblies with defects and automatically leads them to a repair station instead of returning them into the production line. The AOI system is equipped with a special 5 MP RGB camera and LEDs for lighting in different colors. It provides a field of view of 51 x 38 mm with 20 µm pixel resolution. The software that belongs to the system provides a comprehensive component library to ensure easy programming.
