Hello all, We have a customer with a unique application. Part of a 6 layer FR4 PCB will be immersed in a chemical flow. They conducted tests using a board with routed edges and were successful. This application would work better if we could use V-scored boards. The boards would be separated with a "pizza cutter" style de-paneler. The total edge length in contact with the chemical would be almost 18". Does anyone have any information to suggest the V-score would perform worse than a routed edge when it came to chemical intrusion. Unfortunately I do not know what the chemical is so I am unable to tell you what it is. Thanks for any help you can give.
