Quality of PCB Surface Finishes and Test Coupon Optimization
Minář, Jan ; Přikryl, Tomáš (referee) ; Starý, Jiří (advisor)
This master’s thesis deals with measuring and evaluation of wetting for samples of different surface finishes, using a test coupon developed in cooperation with firm Gatema. It deals with surface finishes ENIG and immersion tin. For these samples deals with quality monitoring and periodic testing of these surface finishes. The solder using for tests is SAC305. Test methods are used for simulation of reflow soldering and wave soldering.
Electronic structure and magnetic properties of the materials with strong electron-electron correlation
Kozub, Agnieszka Lidia ; Shick, Alexander (advisor) ; Legut, Dominik (referee) ; Minár, Ján (referee)
In this thesis, we summarize the material-specific theories of strongly correlated systems and apply them to selected materials. We describe and apply the corre- lated band theory methods: the local density approximation plus Coulomb U, and the density functional theory plus exact diagonalization of single impurity An- derson model. First, we investigate the systems containing impurity atoms: cobalt impurity located in the bulk copper and samarium, and neodymium adatoms on the surface of graphene. We present the spectral densities and study the magnetism of those compounds. Afterwards, we analyze three Np-based compounds: NpPt2In7, Np2Ni17 and NpBC. For all three compounds we analyze the spin, orbital and to- tal magnetic moments and the total density of states, as well as its projections for selected orbitals and spins. Moreover, for NpPt2In7 and NpBC we perform the to- tal energy analysis between different magnetic moment arrangements on the Np atoms.
WETTABILITY OF PCB SURFACE FINISHES
Minář, Jan ; Jana, Toulová (referee) ; Starý, Jiří (advisor)
This bachelor’s thesis with measuring of wetting characteristics by the wetting balance method for samples of different surface finishes from the firm Gatema. It deals with influence of the isothermal aging and reflow processes on wetting characteristics of surface finishes ENIG, HAL and immersion tin. The influence of intermetallic layer on the overall wettability is studied in case of the surface finish of immersion tin. Also deals with the wettability of the nickel layer, after stripped off gold, in case of the surface finish of ENIG.
Property Insurance Coverage Selected Municipalities
Sikorová, Michaela ; Minář, Jan (referee) ; Řezáč, František (advisor)
The subject of the thesis is to analyze the current status of insurance coverage selected municipalities, analysis and comparison of offers insurance protection of property from commercial insurance community and the proposed changes in the scope of the cover of the municipality.
Study of biodiversity and account of haematophagous dipterous insects, mainly mosquitoes, in PLA Palava and Litovelské Pomoraví
Gelbič, Ivan ; Minář, Jan ; Olejníček, Jiří
Changes in the biodiversity of haematophagous insects, mainly mosquitoes and effect of artificial flood on the account of mosquitoes were studied in PLA Palava. Global changes of temperature on the biodiversity of mosquitoes in PLA Palava and Litovelské Pomoraví were studied too.
