Utilizing a pressure-sensitive adhesive (PSA) for assembling an electronic device can have certain benefits, such as ease of automation and instant handling or short handling time that may save time, effort, and costs during manufacturing. A liquid adhesive, on the other hand, can provide superior bond strength relative to a PSA such that a device manufactured using a liquid adhesive may perform better with respect to structural rigidity, dynamic response, impact resistance, and other reliability testing. An electronic device manufacturer can take advantage of the benefits of each type of adhesive during device assembly by incorporating both a PSA and a liquid adhesive to bond two substrates of the device, such as a cover glass or sheet and a housing structure or frame.

Hybrid bonding techniques for electronic devices

An electronic device includes an elongated tubular housing. One or more electronic components are coupled to a chassis disposed in a cavity of the tubular housing. A pair of elongated channels are positioned on opposite sides of the chassis and between the chassis and a sidewall of the tubular housing. The channels are tapered or wedge-shaped along their lengths. During assembly, one of the channels may be slid longitudinally along the other, causing the channels to expand laterally, due to their wedge shape, to secure the chassis in the tubular housing. The chassis and the pair of channels provide a thermally conductive path to dissipate heat. During use, heat generated by the electronic components is transmitted radially outward from the electronic components, through the chassis and the pair of channels, and through the tubular housing to the exterior of the portable electronic device.
