Abstract [en]

In this thesis a industrial test process used during the manufacturing of pressure sensors has beenexamined. The examination is aimed to find areas of improvements related to the software that isused in the process. This test process separates faulty components, in this case circuit boards, beforethey are assembled into a finished product. The separation is made by letting a software applicationmonitor how the functionality of the circuit boards is affected during stress by high temperature andvibration. How the process is performed from a operator viewpoint was examined in the productionplant and suggestions from the operators collected. A preliminary design specification ,that wassupplied at the beginning of the thesis, was completed with the information that was gathered. Thekey improvements to the software were that the evaluation of test results should be automatic andthe software solution should be more scalable in terms of the amount of circuit boards that it canmonitor. The completed specification has been implemented in LabVIEW as a prototype applicationthat contains the key improvements of increased scalability and automatic evaluation of results.
