Title:
MAGNETO-ACTIVE ADHESIVE SYSTEMS
Document Type and Number:
WIPO Patent Application WO2005123388
Kind Code:
A3
Abstract:
A magneto-active adhesive and method of adhesive bonding by magnetic field. The method includes steps of providing at least two adherends (24, 26) to be bonded, providing a magneto-active adhesive system (22) between the at least two adherends (24, 26), the magneto-active adhesive system comprising a plurality of magnetic particles and an adhesive; and applying a non-cyclically varying magnetic field or a cyclically varying magnetic field induced by an alternating current having a frequency of less than 100 hz to the magneto-active adhesive system to change the adhesion of the magneto-active adhesive system to at least one of the adherends. Various carriers for microelectronic devices including magneto-active adhesive contact surfaces are also described within the scope of the invention.
