SEHO Receives a 2012 Innovation Award for Its New AOI Feature for Selective Soldering during NEPCON China

Markus Walter, CEO of SEHO Systems GmbH said: “We developed this new function together with a business partner who is an expert in the field of AOI, and in close cooperation with the electronics industry. From selected customers we already introduced this innovation to, we have received very positive feedback. An industry recognition like this award validates that our innovative soldering solutions help to bring the electronics production a step ahead to improve yield, increase production quality and reduce costs.”

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.

Established in 2006, the EM Asia Innovation Awards program strives to recognize and celebrate excellence in the Asian electronics industry, inspiring companies to achieve the highest standards and push the industry forward.
