Evaluation of equipment capability for precision placing of electronic components by using SPC (statistical process control)

Abstract

SPC control is a statistical method for evaluating whether a process is under control and is capable. It has been developed on the basis of comprehensive mathematical statistical methods and it is already largely used for process improvement in the discrete electronic industry. This report describes an SPC study of capabilities for precise and stable placing of electronic components on printed circuit boards. Predictions and real results are presented for a specific assembly machine.
