Minimizing machine set-up time when manufacturing printed circuit boards.
… different types of circuit boards, the machine set-up time becomes much more important than the assembly rate of each board. In order to minimize this set up time, we must try to solve the set-up/sequencing decision problem according to either the MCS (Minimizing Component Switches) or MSI …

Addressing equipment set-up time and manufacturing cost through real time inline inspection in tantalum wire manufacturing
… detect surface defects and monitor diameter real-time during the final wire drawing operation. Throughout his work, it was proven that the new inspection system was able to catch common wire defects under manufacturing conditions (wire speed). Furthermore, defect density limits were defined based …
