Optimalization of soldering process on IR-400
Otáhal, Alexandr ; Nicák, Michal (referee) ; Szendiuch, Ivan (advisor)
This project deals with innovation of IR-400 equipment which is based on design and installation of temperature regulation, in both top and bottom side. This innovation enables adjustment of reflow temperature profile for repair and rework of SMD components by lead-free solder materials for both, FR4 and alumina substrates, as assembly of some special packages.
Analysis of Defects on PCB Using Modern Optical Method
Vala, Martin ; Řezníček, Michal (referee) ; Řihák, Pavel (advisor)
This diploma thesis is focused on detecting of defects on BGA (Ball Grid Array) components using of X-ray. Defects are formed during reflow BGA components during assembly, but also later due to mechanical and thermal stress. Therefore, there is an overview of defects and methods of diagnosis of BGA packages eg .: modern X-ray defect detection or micro sections. There is disclosed a device NORDSON DAGE XD7600NT its operation and setup. The device enables advanced methods of scanning called X-plane. For creating 3D models used reconstructive software called CERA, which uses raw data from the method of X-Plane.
Optimalization of repair process in Surface Mount Technology
Vala, Radek ; Řezníček, Michal (referee) ; Szendiuch, Ivan (advisor)
This project deals with utilizing of IR 400 equipment for assembly and repair of SMD components soldered by lead-free solder materials. The part of the work concerns with optimizing of the temperature profile, which is very important in the repair to eliminate the damage of components and PCB. There was added controller R 500 and cooling equipment to allow better control of the temperature during the soldering cycle.
Solder Wave Process Optimization
Procházka, Martin ; Brno, Martin Štěpánek HONEYWELL (referee) ; Starý, Jiří (advisor)
This work describes solder wave process and it‘s optimalization. It informs us about wave soldering and describes it’s fragments. Next it is described partition of fluxes and their properties. In practical part is described researching of defects on PCB’s and analysis of possible reason of defects, measurement of the weight of sprayed flux and measurement of solderable profile.
Testing of Solders in Protection Atmosphere
Vala, Radek ; Jankovský, Jaroslav (referee) ; Szendiuch, Ivan (advisor)
The project deals with the overall design and construction of equipment called the desiccators for brazing in a protective atmosphere. The device was designed and manufactured cooling and heating element. For the soldering various temperature profiles have been defined and adjusted, as for SnPb as well for lead-free solders. There was a realization of samples were measured and analyzed. Finally were realized micro sections for lead free solder.
Optimization of temperature profiles on equipment IR-400
Mieržwinský, Leon ; Štekovič, Michal (referee) ; Otáhal, Alexandr (advisor)
This thesis focuses to innovation of the cooling module for the repair station Ersa IR-400th Cooling module was designed with possibility to set the cooling rate for FR4 substrate and alumina ceramics. As part work has been optimized temperature profiles for BGA repair package for graphics cards when using leaded and lead-free solder.
