Equipment Uptime and FAB speed, part 1

I like to resume with the posts on the topic of FAB cycle time drivers. As mentioned in an earlier post – these are some of the key drivers for factory cycle time: overall factory size (number of equipment available to run a certain step) overall equipment uptime and uptime stability M-ratio rework rate product…… Continue reading Equipment Uptime and FAB speed, part 1
