A study on statistical process control technology applied in reflow soldering processes

Abstract

SPC (statistical process control) does beforehand control for produce process through symbolic statistics. Compared with usual ex-post control, it can reduce loss and decrease failure rate effectively. In this paper, factors of SPC of reflow soldering processes were analyzed; SPC project of reflow soldering processes was confirmed; SPC models of reflow soldering processes were built; SPC of reflow soldering processes was achieved by MINITAB.
