Wave Soldering Fluxes Comparison
Stoklásek, Lukáš ; Martinec, Petr (referee) ; Starý, Jiří (advisor)
Semestral thesis introduces the problematics of wave soldering fluxes, flux residues and problems of electromigration. Practical part describes measuring of ionic contamination by using conductometric method, measuring the wettability by the wetting balance method and amount of failures on wave soldered printed circuit boards with these fluxes. The main object is to compare quality of the fluxes.

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.

Flux Selection for Wave Soldering
Dyntarová, Markéta ; Jan, Čermák (referee) ; Starý, Jiří (advisor)
The theoretical part of diploma thesis „Selection of a suitable type of flux for wave soldering”, is devoted to problematic of fluxes, flux residues and wave soldering. It introduces reader with requirements of company HC electronics and with selection of a suitable types of fluxes for testing. It also contains theoretical comparison and design of flux testing methodologies. The practical part of the diploma thesis is focused on the selection of a suitable flux for the company HC electronics by performing practical tests according to the previously proposed methodologies, which include wetting balance test method, surface insulation resistance measurement, copper mirror test, soldering test of PCB and ROSE method.
