A dispensing system and method for dispensing material onto a substrate. In one embodiment, a dispensing system includes a housing, a dispensing apparatus, coupled to the housing, that dispenses a quantity of material onto the substrate, and a measuring probe, coupled to the housing, and positionable over the substrate to measure a distance from a reference point to a location on the top surface of the substrate. Another embodiment of the invention is directed to a method for dispensing material onto a top surface of a substrate using a dispensing system having a dispensing apparatus that dispenses the material at a dispensing distance from the top surface of the substrate. The method includes steps of loading a substrate onto a support plate of the dispensing system, positioning a measuring probe above the substrate at a predetermined height above the support plate, measuring a distance between the measuring probe and the top surface of the substrate, positioning the dispensing apparatus at the dispensing distance above the top surface of the substrate and dispensing material onto the substrate.

Apparatus for measuring the height of a substrate in a dispensing system

A dispensing system for dispensing material onto a substrate. In one embodiment, the material is dispensed into a cavity of the substrate, the cavity having an unknown volume. The dispensing system includes a housing, a dispensing apparatus, coupled to the housing, that dispenses a metered quantity of material, and a volumetric measuring probe, coupled to the housing, and positionable over the cavity of the substrate to measure the volume of the cavity. In embodiments, the volumetric measuring probe includes a concave section having a mating edge that is constructed and arranged to create a substantially airtight seal between the probe and the substrate, a chamber, a first valve, disposed between the chamber and the concave section, a pressure transducer coupled to the concave section to determine air pressure within the concave section, an air inlet port, a second valve, disposed between the air inlet port and the concave section, an air exhaust port, and a third valve, disposed between the chamber and the exhaust port. In one embodiment, the volumetric measuring probe determines the volume of material dispensed from the dispensing system.
