Title: DYNAMICALLY RECONFIGURABLE ASSEMBLY LINE FOR ELECTRONIC PRODUCTS
Abstract:
A method of reconfiguring a production line for fabricating printed circuit board assemblies to achieve maximum efficiency and maximum flexibility is disclosed. The production line has one or more placement stations (16, 18, 20), a reflow oven (22), a conveyor (24) and a controller (30). The controller communicates with the various components (placement stations, reflow oven, conveyor) of the production line to transfer information related to the state of assembly of some of the printed circuit board assemblies (15, 17, 19) that are being processed. The controller also communicates information related to the status of the various other stations. The operational functionality of one or more of the placement stations, the reflow oven, or the conveyor is altered in response to the communication by the controller. Other remaining modules continue operation unaltered during this step of dynamic reconfiguration.
