Abstract:
1. A method for using a component delivery system to deliver fabrication components, the system including a delivery conduit, a component storage device, and an unloading mechanism having an extractor catcher, and a back flow port in fluid communication with an upper surface of the extractor catcher the method comprising: creating a vacuum within the extractor catcher to draw a component from the component storage device into the extractor catcher; positioning the unloading mechanism adjacent to the delivery conduit; deactivating the vacuum and allowing the component to fall into the conduit by gravity; and creating an overpressure in the extractor catcher to ensure that the component is released from the unloading mechanism and falls into the delivery conduit, wherein creating the overpressure includes supplying pressurized air to the back flow port.
