3.8 Material Movement
Material movement on the Equipment consists of the following three board holding areas:
Pre-processing Area
Dispensing Area
Post-processing Area
In order for processing to begin, a board must arrive from the upstream machine on the pre-processing
area. The Equipment then takes the boards to the pre-processing area, sends them to the dispensing area,
processes them, and then places them in the post-processing area. Before a new lot can be started, these
boards must be removed from the dispensing area. The following diagrams depict the state transitions for
the input and output ports on the Equipment. Collection events can be triggered only when the board
arrives and leaves the dispensing area.

place. For a complete listing of these collection events, refer to Appendix B.
