Abstract
A method and apparatus for detecting and measuring organic materials present on components used in magnetic storage systems, such as an actuator coil. The component is heated on a hot plate, and a concave lens with a low surface energy coating is placed over the component. The contaminants volatilize and condense on the glass lens. The condensate is collected in solvent. The solvent is evaporated and the size of the residue is measured. A determination can be made whether the component is suitable for used in a magnetic storage system.
Claims14
A method for detecting organic materials on components used in a magnetic storage system comprising the steps of:
- placing the component on a heat source;
- covering the component with a concave lens having a low surface energy coating;
- creating a temperature differential between the heat source and the concave lens;
- vaporizing organic materials on the component, if any;
- condensing the vaporized materials, if any on the concave lens;
- collecting the condensate from the lens with a solvent droplet;
- evaporating the solvent so that only a residue remains;
- and
- measuring the size of the residue.
