The technology evolution of capacitors from a precedent paper in 1993 in which we studied a ceramic capacitor reported on a FR4 substrate to today's is very important. In order to reduce the risk of early failures peculiar to ceramic capacitors, technologists are using new polymer-ceramic materials embedded in the FR4 or FLEX substrate during the manufacturing step. In this paper the robustness of such embedded capacitors regarding the environmental conditions (temperature and humidity) was studied and compared to discrete ceramic capacitors.
