Chosen electrical, noise and stability characteristics of passive components embedded in printed circuit boards (original) (raw)

Abstract

This paper presents systematic studies of electrical, noise and long-term stability parameters of resistors (thinfilm or polymer thick-film) and capacitors embedded in Printed Circuit Boards (PCBs). The temperature dependence of resistance or capacitance were determined in a wide temperature range (from -180 o C to 130 o C) and analyzed as a function of geometry of passives and cladding process. The in-situ accelerated ageing process (basic properties of passives measured directly at ageing conditions) was carried out to perform long-term behavior analysis. Low frequency noise measurements were made in room temperature using noise spectra measurements in dc bridge configuration.
