Biostability of electronic packaging materials

Biostability is concerned with the interactions take place between an integrated electronic system, restoring physiological functions often with a long time application and the components of the human body (tissues, fluids, gases, and applied medicaments). Organism with its specific inner conditions (temperature, pressure, pH-value, liquid flow rate, concentration and complex chemical compound) assures for systems constituents (conduct materials, allows, organic and inorganic semiconductor) a stressed medium which accelerates degradable processes (destruction, migration, dissolution, corrosion, delaminating, functions loss, structure alterations, etc.). These processes-difficult interactions mostly on the boundary surface that stand in depending from the contact time. Our main goal is to consider the principles of these interactions, to study alterations through living organisms dynamic loading, to modulate a long time stability of packaging arrangement under bio-stress, to make dynamic measurements with packaging and housing materials and simulated body fluids (for example physiological sodium chloride water solution, synthetic plasma, simulate Liquor cerebrospinalis fluid), to definite quantitative und qualitative alterations of the fluid and materials surface, to rationalize a selection of biomaterials.
