Isotropic Conductive Adhesives(ICA) conducting electrically and thermally through metal fillers in resin have been studied macroscopically (the total resistance after mount) and microscopically (the contact resistance between fillers). However, the study of the conductive mechanism between electrodes of parts has not been elucidated yet. The reason is that the flat surface (2D) observation is usually used, though the actual dispersion of fillers is the three dimension (3D). In this paper, we observed 3D dispersion and 3D conductive pathway by FIB-SEM which repeats porishing and observation. In addition, thermal conduction and electric conduction are analyzed by this observation result. Then, the electric and thermal interface resistance can be calculated by the comparison of analysis and experiment. Thermal and electric interface resistance quantified by this study would make ICA higher thermal conduction and electric conduction.

Up to now, while automobile electric packages have demanded the high density for small and light products, electric leaks, which have occurred due to condensation, have been a major problem. To prevent any electric leaks, a conformal coating on the electric parts (ex. ECU : Electronic Control Unit) has been needed, but in general the design rules of the conformal coating (ex. Application area) is vague. Therefore, DENSO demands to clear the design rules of conformal coating electric package for higher reliability. To meet the demand, DENSO has developed a condensation simulation method using CAE that can show the occurrence condition of condensation fast and accurately. In the result, DENSO has been able to get the design rules where to need the conformal coating in the electric package for automobiles.
