Hello KA, When producing in kind of PCB product you have to base much of your decision on cost effectiveness, time, and quality. In order to get the best of all three you have to decide which you want to be your top priority. By adding an epoxy to

Sure KA, it's done every day. Be sure that the components to be used on the bottom can take the maximum heat of the wave and the delta T of entering the wave. Depending how complex the bottom side is you will get better results with attention paid
