Abstract

Models of quantum effect photo-detector array towards MCM-package is established to systematically study the fatigue life of solder joint under different geometrical sizes, and stress of different material with temperature changed by softwares. Thermal-mechanical simulations are carried out on assembly model in order to positioning SED dissipated in solder joints and carrier during thermal cycles. Different temperature cycling tests are studied the complex warping effect in BGA. The influence of cycle life by different solder diameter and carrier thickness is studied in detail. At the same time, interactive visualization package model and coupling model is created. The heat conduction problem of pad, new TSV (Through Silicon Via) structure design is discussed. The crosstalk of “a hole with four lines” structure of TSV and transmission lines on the carrier is analyzed in details by ADS software.
