Ducom is one of the leading manufacturer and supplier of testing equipments. Ducom presents photo resist spinner. This equipment is used to coat thin, uniform layer of materials like photo resist, epoxy, and paint, adhesive on substrates of glass, silicon, metal and plastic. The substrate is held on a vacuum chuck. Material to be coated is dispensed to it completely. Chuck is made to spin at a high speed. While most of the liquid on surface is thrown off, last layer remains. It dries quickly leaving a thin, uniform coating whose thickness depends upon speed, surface tension and viscosity.
Features
1. photo resist spinner is based on a hollow shaft motor especially developed for this application.
2. it permits mounting of vacuum chuck directly on the motor shaft, eliminating belt and its related problems of acceleration, tension and slippage.
3. it gives trouble free service.
4. the vacuum chuck is easily detachable for cleaning and change.
