Its depend on your PCBs layout, how much the traces are close to the edges and how you cut the edges by punching or milling (layers separation). Reuven ROKAH Think green before printing this mail... Thanks -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Douglas Pauls Sent: Wednesday, October 20, 2010 8:21 PM To: [log in to unmask] Subject: [TN] Conformal Coating Board Edges Good afternoon all, I am glad we all appreciate Inge and the time he puts into making this a fun and interesting forum. To sum up: Ditto. I have a question related to conformal coating, a sort of survey. For those of you that conformally coat your assemblies, do you coat the edges of the boards? Why or why not? There is an internal debate here and I wanted some other viewpoints before offering my own.
