Study of lead-free solder joints reliability
Pícha, Jan ; Starý, Jiří (referee) ; Szendiuch, Ivan (advisor)
The thesis deals with problems concerning lead free soldering especially the study of the structure of solder joints and their reliability. The thesis evaluates lead free solder alloys. The theoretical part includes basic principles of soldering and methods of investigating solder joints reliability. The experimental part deals with the impact of water cooling and vibration on solder joint structure. Both methods are tested and are evaluated with regard to their reliability. The used tests include X-ray inspection, optical inspection, mechanical tests, investigating joint structure with electrone microscope.

Research of the reliability of lead-free solder joints
Pelc, Miroslav ; Švecová, Olga (referee) ; Szendiuch, Ivan (advisor)
This work deals research of the reliability of leed-free solder joints. It summarizes the basic knowledge of lead-free solder alloys, soldering and testing process, the soldered joints. The work is done selecting the most important factors entering into the soldering process. The method of the DOE sought the optimal combination of factors, which would correspond to the highest quality solder joints.
