“How can conformal coatings effectively and cost-efficiently be checked?”
“Applying conformal coating is the last step within the PCB production cycle. Similar to the previous production stages, quality assurance measures must be executed. After coating the assembly, proper wetting is mostly visibly checked by manual means. Because manual optical inspection has proven inappropriate for high PCB output, so called automated optical conformal coating inspection systems have been developed. They enable automatic testing of the correct wetting within the production line cycle.”

Dr Joerg Schambach is Team Manager for GOEPEL electronic’s business unit Industrial Vision Solutions, responsible for the development and manufacturing of optical inspection systems for surface inspection, LED checking, display control and much more. Dr Schambach brings lots of experience from hundreds of projects, many of them customised solutions and is therefore well qualified to speak on matters relating to automated conformal coating inspection systems as well as many special issues on optical inspection of PCBs and neighbouring topics.
Each Month as part of the Nexus Newsletter a panel of experts are asked their opinions on a challenging area in conformal coating. Their responses are published to help others solve their issues.
The Experts for Conformal Coating come from a range of backgrounds and areas allowing a wide scope for knowledge transfer.
