Methodologies to improve experimental research processes in soldering technology

Abstract

This article introduces the possibility of using optimization methods Failure Mode and Effect Analysis (FMEA) and Design of Experiments (DOE) to improve experimental research processes. The FMEA methodology was implemented in the pre - experimental phase of the experiment. Potential risks has been established by FMEA methodology. Risks that should affected the overall result of the experiment have been determined in brainstorming process. These risks were tested during the experiment and data were evaluated by DOE and Student's t-test method. The results of this research confirmed that proposed methodology helped to verify the major risks which have significant impact to results of an experiment.
