REBALLING OF BGA PACKAGES USING PACE TF2700 EQUIPMENT
Roháček, Peter ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
The Diploma thesis is focused on reballing of BGA packages with the device PACE TF 2700. It describes the general types of BGA packages, their defects, importance of thermal management to the solder techniques, where it is also talked about the meaning of solders and fluxes for the joint. The work informs about the most common methods of reballing, the proper handling of components and the current situation with BGA stencils on the market. It briefly describes the device operation of PACE TF 2700, that is working on the convection and IR principle of heating components. It deals with the manufacturing of the template, dummy BGA packages, the test plates, creation of the thermo profile, comparing and examining the defects and their causes, which had the most significant impact on the results. The achievements would serve for comparing them with the results of the future laboratory exercises or as a subject for further works.

Visualization of input parameters for radiation transfer in plasma
Kubovič, Tomáš ; Aubrecht, Vladimír (referee) ; Kloc, Petr (advisor)
This bachelors thesis focuses on simplification of the input parameters for electrical arc radiation transfer calculations. In the first part, we learn basics of transfer for thermal radiation and calculation of the absorption and emission coefficients. Next part is devoted to the design of absorption model and describes various parts of the model. It is followed by a graphical design of the interface which also displays various graphs. The next chapter explains the operating principle of the software application. The last chapter shows an example of the plot for computing domain.
