Basic measurement of bipolar and unipolar transistor
Kaňa, Leoš ; Šebesta, Jiří (referee) ; Dřínovský, Jiří (advisor)
In terms of the better effectiveness in the sphere of transistor characteristics measuring, no matter unipolar (FET) or bipolar (BJT), in laboratory conditions and their better understanding in terms of thrash out a subject matter is desirable have to available workplace let us say preparation enabling this kind of measuring with modifiability wiring and with possibility to change measured component. This thesis isn‘t focused only on development of this kind of universal component for measuring but simultaneously contains brief summary about the theory and parameters of transistors. Next aim is the development and realisation of static characteristic measuring program in VEE 8.0 Pro environment. Finally the complex laboratory exercise has to be done for measuring of bipolar and unipolar transistor’s static characteristics include programs for automatic measuring. For developing of DPS was used developing system named Eagle which gives us instrument with sufficiently accuracy. In thesis is contained theory needed for measuring and programming. Except possibility of measured component change we can change transistor connection in circuit on the board. This change is available for BJT (CE, CB, CC) and unipolar JFET (CS, CG, CD) transistor’s.

Design system for the detection and quantification of requirements to the control system of intelligent house
Kotík, Miloslav ; Novotný, Jan (referee) ; Bátora, Branislav (advisor)
Bachelor thesis focuses on analysis of the investor's requirements for control system of intelligent house. It is designed questionnaire to guide the designer in communication with the investor and this process is converted into an interactive form as a schedule. On the basis of the questionnaire is designed a procedure for automatic evaluation and transfer of detected investor’s requirements into the list of recommended components of a Tecomat Foxtrot control system and its peripherals for implementation. The first two chapters are theoretical and describe the intelligent house and the Tecomat Foxtrot control system. The last chapter of bachelor thesis describes the Design system itself and its parts - questionnaire, database, form, program evaluation.

Semiautomatic Dispenser Application in Flexible Low Series PCB Assembly in SMT
Prikryl, Petr ; Zatloukal, Miroslav (referee) ; Starý, Jiří (advisor)
The aim of this thesis is solving the issue of introducing the Dotmaster semi-automatic dispenser into the flexible low series surface mount technology assembly of printed circuit boards. The first part of the thesis deals with the issue of introduction to the dispension of solderpastes, adhesives and packaging materials. The second part is focused on the description of the Dotmaster semi-autamatic. The last part is devoted to actual measuring and observation with the device using PD 860002 SA adhesive made by Heraeus company and SAC solder paste by Kester company. Showing the characteristics of dependecies of the shape of the dispensed adhesive and solder paste on several parameters of dispension follows.
