Controlling of diagnostic process when failures in manufacturing process occur

The paper deals with controlling of diagnostic processes when failures in manufacturing process occur. The aim is to make an experiment and try to prove that "failure diagnostics" can be controlled. We will focused on developing some precautions which could be used as a tool for controlling and following improvement of diagnostic processes in case of occurring failures. The diagnostics system is an important tool for management set correction and improvement processes. Therefore, it increases their importance and also the effort to their controlling and following improvement on the field of solving problems and failures. The aim of the precautions is to ensure Zero-defect Manufacturing. Our experiment is focused on area of solderability testing because this area is directly connected with manufacturing processes and diagnostic processes have to start for detection of cause of the failure/problem.
