“…Merely some organic salt bonds are extremly toxic due to the denaturing of proteins. The first biostability studies of these coating systems have been carried out and described in [2]. The investigations were accomplished in synthetic body fluids such as artificial blood plasma (ABP), artificial cerebrospinal fluid (ACF) and 0.9% NaCl dynamically at the ambient temperature of 60°C.…”

During the last years a lot ofactive implantable medical devices like neural prostheses [1] and sensors have been produced. For such systems a long term reliability under the influence of aggressive physiological conditions is very important. To protect them a stiff housing is normally utilised. In some cases, ifthe requirements for a low weight, flexibility and perhaps a need to transmit optical signals have to be fullfiled, they aren't the best choice. Another possibility is the use offlexible protection materials like polymers, which have the advantageous properties. Finally their structure isn't completely impermeable for different components contained in physiological fluids. Some promising polymers are Poly-Para-Xylylen (Parylene C) and silicone rubber . This paper shows the results of our tests to their ability to function as encapsulants for the PCB configurations FR4+Cu+Ni+Au, FR4+Cu+chem. Sn and FR4+Cu+HAL Sn.
