The Modus Advantage in Conformal Coating Automated Inspection of Printed Circuit Boards

Modus offer full solutions in both inline and offline (batch) inspection of conformal coated Printed Circuit Boards (PCBs) which can use both fixed camera and scanner based image processing to give flexibility to the customer in their custom solution.

Conformal Coating Inspection is a critical and often neglected stage of the conformal coating process. The standards such as IPC A 610 are explicit in their requirements for conformal coating inspection yet few companies actually inspect to that level.

SCH Technologies are working as a partner with German company, Modus, to provide an Automated Conformal Coating Inspection System for automatic inspection of conformal coatings and defect detection. Modus have 25 years of experience with image processing being pioneers at developing scanner based industrial image processing systems. The solutions Modus provide today are complete software and hardware development from one source with specific long time experience in the automotive area.

Parallax Free Processing

Modus have made unique technological advances in parallax-free image capturing for conformal coating processing. Fixed camera solutions or scanners with a fixed camera system at the centre can suffer from parallax where high sided components can cause shadows in image processing.

The Modus Parallax free scanning system utilises a specialist lens which removes the parallax issues from the scanning process and eliminates shadows down the sides of high components.

UV LED Lighting

Modus use Multi-LED lighting systems using six LED-Lines with special optics to provide a homogeneous light source. This means the UV-Light is perfect for the use of inspection of UV fluorescent conformal coatings.

The Complete Solution for Conformal Coating Inspection

About Dr Lee Hitchens

Dr Hitchens has been working in the electronics industry and the area of conformal coatings for over 25 years in various areas including sales and technical support. He has also been training people for almost the same amount of time in all areas of conformal coating whether that is materials & equipment selection, process development or troubleshooting to help them solve their particular problem. Recently, he decided that the industry needed a specific place where all of the useful knowledge on conformal coatings could be collated for users to find easily and use in their own production process. So, Nexus was born and he began the Nexus eBook project.
