I need some information for soldering and conformal coating operation. 1) We placed TH components on the PWBs but we did not pass these boards from the wave solder. They are waiting at the production area .( at the room temperature). Is there any standard to keep these boards or any time limits for corrosion effect? 2) Before the conformal coating operation , Is there any time limit or standards to keep for the soldered boards?
