Ido, Over 20 years ago I worked for a medical OEM that made implantable electronic devices. I believe we used parylene conformal coating on the electronics. Sorry, but I don't remember who manufactured the parylene.

We need it all to stand to FDA requirements. We are looking for methods to close(encapsulation/enclosure.) the PCB before casting it in the silicone piece for 1. Protecting it from the pressure and heat in the silicone casting, about 160-180C for couple of minutes 2. Protecting it from the water that will pass the silicone which has high permeability for water. Any suggetions?
