MOISTENING OF COMPONENT MATERIALS AND SPEED OF DEHUMIDIFICATION
Pospíšil, Tomáš ; Tomáš, Bžoněk (referee) ; Starý, Jiří (advisor)
This bachelor thesis deals with process associated with moisture in electrotechnics. The bachelor thesis is focused on the components and basic materials that are sensitive to moisture and defects caused by moisture in the reflow soldering process. The theoretical part describes the principles of measuring humidity and sorts of absorption. Furthermore this work described the basic classification and defects in components, base materials and packaging material sensitive to moisture and selection of standards dealing with this issue. Another theoretical part is focused on the manipulation with components and materials sensitive to moisture. The practical part deals with the methodology and practical measurement of moisture soaking in the components and materials with respect to their level of sensitivity to moisture. The following part is focused on the methodology of drying, practical measurement of drying and comparing two drying cabinets.
