Viscom optical 3D solder joint measurement combines software and camera module

Combining intelligent software and the high-performance camera module XMplus, Viscom believes it has perfected automatic optical inspection (AOI), which also includes optimal 3D solder joint measurement. Users can now receive definite and easy-to-interpret information, says Viscom, and,quality assurance for electronic components.

Solder joint measurement using 3D AOI is a central component of the company’s release of vVision and SI, presented at the SMT show in Nuremberg, Germany. The access to exact measuring results helps users to create 3D AOI inspection programs and thus ensures a high efficiency. The 3D measurement with the high-speed Viscom XMplus camera module produces easy-to-classify height and position values, says Viscom. Users can easily interpret these intuitive values, it adds.

Quality of the data is important for accurate, reliable measurement. To evaluate a solder joint with 3D AOI from Viscom, several height profiles are measured at the solder meniscus with a high resolution of 10micron. The XMplus camera module is suited for this task. Its angled cameras ensure the best panorama view of components and their solder joints from all eight directions. The high-performance software also guarantees maximum speeds throughout the measurement and inspection process.

The measured profiles of a solder joint are evaluated using a mathematical procedure. An additional advantage is that improved evaluation results in fewer false calls and thus increases production efficiency. This combination of intelligent software and very powerful hardware offers customers options for efficient use.

Besides evaluating solder joints, exact detection of component orientation is also an increasingly important application. For example, in the ever-smaller LEDs that are increasingly being installed in vehicle lamps and headlights, even minimal tilting is a defect. Exact measurement values are needed for a final quality evaluation, and these are ensured with a Viscom 3D AOI.
