Currently, the model change frequency is more than 800 times in a month as an average.
We can save N2, electricity and man power by reduce it to half.
*Monthly basis expense/line : 282kB/month
N2: 88kB, Electricity: 50kB,
Worker - 8 person/line (3 person, 7 to 7): 144kB
Based on the results in year 2013
800 times of model change nearly equal wiyh the operation of SMT 5 lines.
It becomes the cost saving about 2.5 lines operation per month by reduce the
model change times to half.
