Application of production line balancing technique for productivity with electronic assembly industry (Thai)

Abstract

In Switching Power Supply manafacturing process, the bottle-neck frequently occure and lead to
process termination, dismiss manufacturing plan and over-time work. From the late product distribution
problem and their effects, the ECRS tool was selected for analyzing and improving the manufacturing process.
The principle of the line balance were also applied to the process estimation. The bottle-neck problem and
process effectiveness were significantly improved by the decreasing of maximum time in a substation from
30.6 sec to 24.5 sec. From 6-over- cycle-time substation , it could be reduced to 2 substations leading to the
higher process efficiency 91.74% from 74.56%. The number of products can be improved upto 22.50% and,
from lay off one man power, 55,151 bath per year can be saved.
