ABSTRACT
According to the manufacturing process
of electrical products, the variation of
temperature is one of the important factors
that influence the motherboard quality. In
order to enhance monitoring power in
manufacturing, a new modified EWMA
control chart was established and verified as
the tool in the manufacturing process that
revises the Weight mode of original EWMA
control chart. Results show that
self-Weighting EWMA control chart can
detect the uncertainty early and respond the
process state that is fine for manufacturing
process monitoring when the process adopts
the real time process control. Furthermore, the
study uses measurement techniques with
computerized monitoring system integrated
Microsoft Office software “EXCEL”, it offers
a good reference to the relevant industry for
improving product quality and efficiency of
process control.
