Thermal stress-strain simulation analysis of BGA solder joint reflow soldering process
A three-dimensional finite element analysis model of BGA components was established.Using ANSYS,this model was subjected to stress-strain finite element simulation analysis under thermal-structure coupling conditions.The influence of temperature field distribution and stress-strain during BGA solder joint reflow process was studied.The results show that the reflow soldering process of the BGA assembly is simulated,with different temperature zones,the temperature distribution of BGA solder joints is uneven and the temperature is more close to the center temperature of the Assembly,the stress and strain of the solder joint is reduced after the heat preservation zone and the Reflow area,and the stress strain will increase when the cooling zone is over.
