Controllable Placement of Liquid Adhesive on Substrate
First Claim
1. A method comprising:
- dispensing a liquid adhesive into a designated area on a surface of a substrate;
controllably applying energy to at least a portion of the dispensed liquid adhesive in the designated area to confine the dispensed liquid adhesive to the designated area; and
curing the confined liquid adhesive.

Abstract
Controllable placement of a liquid adhesive on a substrate to confine the adhesive to a desired area of the substrate is disclosed. A controllable placement method can include dispensing a liquid adhesive into a designated area on a surface of a substrate, controllably confining the dispensed liquid adhesive to the designated area, and curing the confined liquid adhesive. The dispensed liquid adhesive can be controllably confined using various techniques, such as electrical repulsion, electrical attraction, capacitance, electrowetting, light curing, adhesive attracting-repulsing coatings, and substrate topography. A substrate having a controllably placed liquid adhesive thereon can be incorporated into electronic devices, such as a mobile telephone, a digital media player, or a personal computer.
