The aim of this study was to clarify the possibilities and feasibility of the ther-mal simulation for the modeling of the rework process.
The rework process modeling could enable an easy and fast access to the component and PWB level thermally critical effects like over and under heating of the component during the rework process. The modeling could also be used as a help of the real rework profile definition at an early phase of the electrical device development.
The work includes a thermal modeling of the rework station, a rework profile, a test board and the test component. This leads to the millimeter scale forced convection integration to the transient simulations. Finally, the simulation results were verified against to the real measurements of the rework process. This will ensure the feasibility of the simulations for the rework process and the correctness of modeling methods.
As a result of the study the millimeter scale forced convection model of the re-work station was created and verified against to the measurement results. The results show a good correlation with the measurement and the simulated results. This also indicates the feasibility of the selected modeling method for the rework simulations. The most suitable simulation parameters for the rework simulation profile control were also defined.
