Method of making a filter device |
摘要 |
A filter device filters contaminants from air for magnetic disk drive systems. The filter has layers of permeable fabric material allowing flow through the filter. An adsorptive slurry is deposited in a discreet pattern onto one layer with a cover layer mounted over the adsorptive deposit. The slurry retains a high adsorptive material surface area for improved adsorption of contaminants. The slurry is placed onto the base material using a screening or other similar application method.
