Abstract: A method of encapsulating an electronic component. The method includes applying a first layer of an encapsulating composition onto an electronic component from an applicator roll, the electronic component being disposed on a substrate. The applicator roll comprises an outer surface and is spaced apart from the electronic component such that a gap exists between the applicator roll and the electronic component. The gap controls the thickness of the first layer of encapsulating composition. The first layer of encapsulating composition encapsulates the electronic component on the substrate. An interface between the surface of the electronic component and the encapsulating composition being substantially free of voids.

Abstract: The hot melt compositions of this invention include from 15% by weight to 60% by weight of a styrene block copolymer, from 15% to 75% by weight of a wax having a Congealing Point (ASTM D938) of from 45° C. to 90° C. and optionally a propylene based polymer. The hot melt composition can be free of both tackifying agent and plasticizer and is useful in a variety of hygiene applications.
