Design of bonding system for PCB repairs
Burian, Jaroslav ; Skácel, Josef (referee) ; Otáhal, Alexandr (advisor)
The goal of this thesis is to design a device for PCB repairing, mainly for conductive traces and soldering pads. The design focuses on mechanical construction, control unit and controling of the whole device, which is semiautomatic. A great deal of emphasis is placed on the simplicity and versality of the construction. The teoretic part of this thesis is addressed to the printed circuit board and its repairs. There are presented existing devices for repairing of those defects in the second part. The next part is focused on the design itself in terms of mechanical construction and choosing electrical components. There is described controlling of these components. Part of making mechanical components follows. Last but not least, firmware, which controls whole machine is described there. Finally, the machine was tested in the repair process of the solder pad on the printed circuit board.

System for evaluation of upsetting test
Janečka, Dominik ; Podaný, Kamil (referee) ; Řiháček, Jan (advisor)
The thesis deals with the proposal of measurement system for evaluating upsetting test. The variables for evaluating the test are obtained by using sensors of measuring devices. The necessary magnitudes are force, track and temperature. For this purpose they were used sensors HBM R6C, HBM W50 and thermocouple type K. The sensor signals are amplified by measuring modules Dewetron and transferred to a PC by measuring card NI USB-6009. There are further processed by evaluation program DEWESoft 6.5. In a final part are performed a verification measurements to assess system function.

Trigger pull measurement system
Hrabica, Jan ; Mancl, Vlastimil (referee) ; Beneš, Petr (advisor)
The topic of this bachelor thesis is proposal of system for the measurement of trigger pull and for pistols of the company Česká Zbrojovka, a.s. Uherský Brod. The aim of this work is the introduction into the problematics, assessment of current state in the production establishment and proposal of device for measuring the required parameters.
