Realization of hybrid integrated circuits leads for high-temperature applications
Valíček, Jan ; Jankovský, Jaroslav (referee) ; Řezníček, Michal (advisor)
Bachelor thesis deals with realization possibilities of hybrid integrated circuit terminals for high temperature applications. It describes the realization method of direct mounting of terminals, this method of fixation using the conductive paste for the thick film technology. It also describes the selection of suitable materials and the temperature profile in the reflow and muffle furnace and follow removal of terminal oxides. Furthermore, a method for testing of terminals thermal resistance was realized. In conclusion, the method shows increased mechanical strength with the using of dielectric paste.

Mounting of leads by brazing on alumina substrate
Neradil, Petr ; Adámek, Martin (referee) ; Otáhal, Alexandr (advisor)
Bachelor´s thesis deals with the issue of implementation hybrid integrated circuit terminals for performance applications. It also states the advantages of each type of terminals and their technology. It discusses the materials used for brazing and describes problems of brazed in the electrical industry. The thesis also presents techniques for brazin of leads by brazers on the ceramic substrate. The conclusion contains the results of thermal and mechanical tests of the resulting connection.

Monitoring the impact of ultrasonic energy to the leveling of thick film pastes
Pokluda, Tomáš ; Buršík, Martin (referee) ; Řezníček, Michal (advisor)
This bachelor thesis is focused on the problem of levelling of a profile by ultrasound after printing thick layer pastes and on electrical resistance and geometrical dimensions changes. It describes a creation of hybrid integrated circuits, thick film technology and the screen printing method. It also includes basics of fluid physics, basics of fluid rheology, and description of principles of the used ultrasound transducer. Records of the levelling measurements are presented through the use of photographs, comments, tables and graphs.
