Bismuth Low Temperature Solder Pastes
Švéda, Miloš ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
This master´s thesis deals with bismuth low temperature solder pastes. Describes the properties of bismuth solder pastes. It shows the process of manufacturing a printed circuit board for test. The thesis also characterizes laboratory temperature profile setting for the BiSn soldering pastes. Solder paste printing and placement 0 ohm rezistors to printed circuit boards with different surface finishes in the manufacturing plant. Setting of solder profiles for low soldering pastes in reflow oven. Testing resistence of mounted zero resistor on the test board at different aging temperature were analysed. Resistance measurement after a specified time. Testing of solder joint strenght of printed circuit boards for different surface treatments. Changes in structure wereanalysed on microsections for solder pastes.

PCB s Cleaning from Prototypes to Low Series Production
Švéda, Miloš ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
This bachelor thesis deals with the construction of the cleaning unit for prototype and low series production PCB cleaning. It describes the methods used for PCB cleaning, mainly for removing flux residues. It briefly describes the test methods for measuring contamination. It deals with the selection of individual components for cleaning equipment construction and compatible chemistry for flux residues cleaning.
