Design of Reflow Soldering Station for Reballing of BGA Packages
Janiš, Adam ; Szendiuch, Ivan (referee) ; Otáhal, Alexandr (advisor)
This thesis deals with the design of a soldering oven for BGA reballing in a nitrogen protective atmosphere. The principles of reflow soldering, the advantages of a nitrogen protective atmosphere on the quality of solder joints and the types of soldering devices are described. The BGA packages´ part consists of their characteristics, assembling methods, a rework and repair process and solder joint inspection methods. Design of the device, as well as heat flow simulations, are included in the experimental part and particularly it also describes the used structural elements and the principle of function of the individual parts of the device. At the end of this work, the soldering process was measured and the ability of the sample soldering was verified.

Mechanical properties of materials for 3D printing
Janiš, Adam ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This thesis focuses on the description of 3D printing technologies using the FDM method, which uses deposition of molten thermoplastics and their subsequent cooling and solidification layer by layer. This unique structure then shows a strong anisotropy of mechanical properties and, as a result, their testing and print settings are very important. Tensile testing of plastic materials, including indicators of mechanical properties, are described in this thesis according to ČSN EN ISO standard. The practical part presents the concept of a device capable of performing these tests. The block diagram indicates the functional elements and the connections among them. Tensile strength test is described together with results processing. Necessary product documentation is also included.

Design Of Reflow Soldering Station For Reballing
Of Bga Packages
Janiš, Adam
This article deals with the design of a soldering oven for BGA reballing in a nitrogen atmosphere. The principles of reflow soldering, the advantages of a nitrogen atmosphere regarding the quality of solder joints and the types of soldering devices are described. The main aim of the experimental part is to design the soldering station and to simulate the heat flow during soldering using SolidWorks Flow Simulation. Final stage of this work is based on verification of designed soldering station and optimization of soldering process.
