Dendritic Growth

Mar 23, 2015 | -clean" (more appropriately called low-residues) combined with residues from board fabrication, component fabracation, and the assembly process can combine with moisture (even humidity caused moisture) and electrical current to create ECM issues including dendritic growth and parceedic leakage. The best way to ensure ECM issues can not form is to remove the residues that cause ECM. Here's a link to a recorded technical presentation on modern ECM issues. It's about an hour long so clear your schedule :-) https://vimeo.com/100244222 Mike Konrad
