A system for mounting a hubless glassmaster onto a spindle of an orders measurement device includes a magnet and a hub made of a magnetic material. The hub is designed to fit on the spindle of the measurement device. The magnet is placed on a top surface of the glassmaster and the hub is centered and placed on the bottom surface of the glassmaster opposite the magnet. The magnetic forces between the magnet and the hub hold the hub securely to the glassmaster as it is mounted onto the spindle and rotated in the measurement device. In a preferred embodiment, the hub is first placed in an alignment fixture and the glassmaster and magnet are placed on top of the hub to secure the hub to the glassmaster. The glassmaster assembly is then removed from the alignment fixture for mounting. The system allows both hubbed and hubless glassmasters to be tested on the same orders measurement device without having to affix a hub permanently onto the hubless glassmasters with adhesive.

System for mounting a hubless glassmaster onto an orders measurement

The present invention provides a system and method for thermally curing polymeric coated substrates by effective drying of solvents used in the production of the coated component. A feedback system coupled to a heating apparatus is comprised of one or more gas sensors internal or external to the heating apparatus to provide monitoring of the quantity of solvent gases being generated. The present invention allows the curing process to be precisely controlled, where, for example, a predetermined concentration of solvent gases input to the gas sensor can trigger the heating process to be stopped or to provide for a controlled cool down period for curing of the photoresist substrate. A controller coupled between the gas sensor and the heating apparatus may also contain temperature and/or time controls for varying the output of the heating apparatus in response to indications from the gas sensor. The system of the present invention assures production of stable photoresist coatings and also minimizes the processing time needed to properly cure the polymeric coated substrates.
