Tips on designing with Teflon: Don't use solder mask If you do, use only where needed. Also, remember, solder mask sticks better to Copper than to the Teflon. Add non-platted holes where ever possible to allow for moisture escape. Long baking cycles required to remove moisture. Sources for further documentation: IPC D 275 Rogers Solidine. MEETING CLOSED.
