Flux Residues after Reflow Soldering
Uhlář, Vít ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
The aim of this bachelor thesis is to solve flux residue characteristics on PCBś after reflow soldering and compare different solder pastes. The first part deals with the issue of solder paste application and flux residues. The second part focuses on the process of reflow soldering. The third part is devoted to the measurement methodology of flux residues. Finally, project is a practical part, which is summarized in the production of test samples and contains measurement results.
Dielectric Properties of Epoxy with Ground Mica
Bednář, Pavel ; Polsterová, Helena (referee) ; Havlíček, Svatopluk (advisor)
This thesis deals with the dielectric relaxation spectroscopy applied to samples of an epoxy slip filled by grounded mica with granularity of 40 m. The changes of dielectric properties were investigated depending on the fulfillment of grounded mica, temperature, the relative air humidity, and the frequency between 100 Hz and 1MHz.
