METHOD OF FIXING MICRO-SIEVE TO SUPPORT MEMBER AND SUPPORTEDMICRO-SIEVE

摘要

A method is provided for securing a metallic microsieve which comprises; (a) inserting a metallic microsieve within the well of a frame-like support member, at least a portion of the upper edge of the well being fabricated from a fusible material and the height of the well wall being greater than the thickness of the microsieve; (b) directing a laser beam against a point on the upper edge of the well to melt fusible material in contact with the laser beam; (c) permitting the laser-molten fusible material to travel down the wall of the well and contact the edge of the microsieve; and, (d) permitting the laser-molten fusible material in contact with the edge of the microsieve solidify thereby forming a retaining member which secures the microsieve to the support member.
