3D based analysis for PCB jet printing using ultra-close range photogrammetry

Das PCB Jet Printing ist eine innovative Methode um Lotpaste ohne die Verwendung von Schablonen auf Leiterplatten (PCB - printed circtuit board) zu applizieren. In Fertigungslinien enthaltene Inspektionssysteme sind in der Lage zu entscheiden, ob eine Leiterplatte korrekt bedruckt wurde und somit weiterverwendbar…

Single image camera calibration in close range photogrammetry for solder joint analysis

Printed Circuit Boards (PCB) play an important role in the manufacturing of electronic devices. To ensure a correct function of the PCBs a certain amount of solder paste is needed during the placement of components. The aim of the current research is to develop an real-time, closed-loop solution for…

Experimental computer tomograph : investigation and implementation of iterative reconstruction techniques and modern computer…

The computed tomography is one of the most important medical instruments, allowing the non-invasive visualization of cross sections which are free from superpositions. Since 2000 an experimental computer tomo-graph of the third generation for the purpose of education and research was set up and further…
