Abstract
A system and method for using a spray/liquid particle count (LPC) to measure particulate contamination is disclosed. Initially, a component for particulate extraction is received. A sprayer is provided for spraying a liquid on the component. In addition, a container is provided for catching the liquid spraying on the component. The container is clean prior to receiving the liquid and the liquid is collected for later analysis of a number of particles extracted from the component.
Claims18
A method for using a spray/liquid particle count (LPC) to measure particulate contamination, said method comprising:
- receiving a component from a hard disk drive as said component for particulate extraction;
- providing a sprayer for spraying a liquid on said component;
- and
- providing a container for catching said liquid spraying on said component, wherein said container is clean prior to receiving said liquid and said liquid is collected for later analysis of a number of particles extracted from said component.
A spray/liquid particle count (LPC) component particulate extractor for extracting particulate from a component of a hard disk drive comprising:
- a retaining mechanism for receiving a hard disk drive component for particulate extraction;
- a sprayer for providing a stream of spraying liquid to said hard disk drive component;
- and
- a container for catching said liquid spraying on said hard disk drive component, wherein said container is clean prior to receiving said liquid, wherein said liquid is provided to an LPC analyzer for counting a number of particles extracted from said hard disk drive component.
