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.

Subject: [TN] pcb encapsulation for medical use

 

We need to put a small pcb inside silicone rubber that will be in
contact
with body fluids and cleaning with water and alcohol.

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?

 

Thank

 

Ido Mashall
