Based on the of process improvement on the handling time in the visual inspection process as discussed earlier, a
case study was conducted in a semiconductor company located in North, part of Malaysia. The company is equipped
with highly automated state-of-the art facilities and leading technology in manufacturing printed circuit board
(PCB). The company comprises a full range support and services from circuit design, prototype fabrication and mass
production up to flex assembly. This case study mainly focuses on Quality Control (QC) Department which controls
the product quality. The company is trying to grow as a highly competitive company, but high wastage is the main
problem of which is due to high inspection time and handling time. Therefore, in order to show the applicability of
process improvement methodology, it is adopted phases by phases as shown in Figure 1. A detail discussion of the
each phase is given as in the following section.
