Abstract: Conductive adhesive is commonly used in the interconnection of components in microwave circuits, the interconnection reliability is essential for the long-term stable operation of the device. Based on the analysis of conductive adhesive interconnect failure modes in the power module, the article explores the impact of the side conductive adhesive volume on the reliability of capacitor interconnects. Through simulation and experimental analysis, the force of the side conductive adhesive bonding capacitor under different temperature is studied. The results show the internal stress is the smallest and the interconnection strength is the best, when the height of the conductive adhesive is one fourth of the height of the capacitor.
