Hard disk drive filter

摘要

There is provided a method of forming a shaped sorbent filter preferably having a three dimensional shape.The method generally entails:a) providing porous flexible tubular web structure having two open ends;b) sealing a first end of the tubular web structure;c) filling the sealed tubular web structure with flowable filter material of sorbent material and binder;d) sealing the opposite open end of the tubular web material; ande) heating the tubular web structure to active the binder and form a shaped sorbent filter. The tubular web structure preferably is deformed while it is heated so that there is provided at least one permanently deformed bending portion. The invention method provides a simple effective process for forming complex overwrapped shaped small sorbent filters for use in the electronics industry.
