Unformatted text preview: n an electricity intensity basis, shown in Figure 5-3, the
MTSA machine is the single largest electricity user in CCA by a significant amount.
In light of the analysis presented in Figure 5-2 and Figure 5-3, we decided to focus on improving
the efficiency of the high intensity equipment on the left side of Figure 5-3. Specifically, we would
focus on improving the efficiency of the MTSA machine, the vacuum system, the two wave solder
machines, the four SMT ovens, and the four washers (in that order). The decision was made with . ................. . ............

(c, Figure 5-2: Pareto chart of the typical weekly electricity use for equipment in CCA by the category
of equipment. For example, the category "workbenches" include the sum of the electricity used by
the approximately 300 workbenches in CCA. The left axis refers to the bars, and the right axis
refers to the line. Measurements we...
