Methods for assembling electronic devices with adhesive
09565773 · 2017-02-07 · ·

An electronic device may have housing structures, electrical components, and other electronic device structures. Adhesive may be used to join electronic device structures. Adhesive may be dispensed as liquid adhesive and cured to form adhesive joints. Adhesive joints may be debonded. Chain reactions may be initiated by applying a localized initiator such as a chemical or localized energy to the adhesive. Once initiated, the chain reaction may spread throughout the adhesive to cure the adhesive, to globally change adhesive viscosity, or to weaken the adhesive to facilitate debonding. Local changes to adhesive may also be made such as local increases and decreases to adhesive viscosity. Chain reaction curing may be used to cure adhesive or debond adhesive that is hidden from view within gaps in the electronic device structures. Viscosity changes may be used to control where adhesive flows.
