Electrical and thermal characteristics of lead-free solder joints
Jurásek, Matěj ; Adámek, Martin (referee) ; Schnederle, Petr (advisor)
This wok is focused on the issue of soldering. The theoretical part describes the basic requirements for materials and solders alloys, which enter into this process. Further also factors that have a major impact on the quality of joints and methods, that are used for final testing of electrical and optical properties. The aim of the practical part of this work will be monitoring changes in electrical properties depending on the base material, surface finish PCB contact surfaces, the type of solder alloy and residual oxygen concentration in the atmosphere. The resulting values are compared, and they will draw the final recommendations for the method of soldering used alloys
