Reliability Aanalysis on the Solder Joints in Space Cable Connectors
High reliability is prerequisite requirement for the solders in the space electronic products for its inconvenient in-orbit servicing. Based on the finite element method, the reliability of connector solder joints in cable out of a space craft is analyzed when the environment temperature varies in a large scale range within a day, in which the temperature may reach 120 ℃ in the daylight but decrease to -180 ℃ in the night with a transient rate of change upper 2 ℃ per min. The result is available for predict the fatigue life under the cyclic thermal load and developing programs about processing and accelerated environment test.
