Computing device bonding assemblies
View Patent ↗The description relates to computing devices, such as mobile computing devices. One example can include a first portion, a second portion, and an adhesive. The example can also include micro heaters positioned proximate to the adhesive. The micro heaters are configured to be selectively energized to supply sufficient thermal energy to the adhesive to facilitate curing of the adhesive.
1. A device, comprising:
a first portion and a second portion;
a temperature sensitive adhesive; and,
micro heaters positioned proximate to the temperature sensitive adhesive,
wherein the micro heaters are configured to be selectively energized to supply sufficient thermal energy to the temperature sensitive adhesive to produce a relatively pliant state of the temperature sensitive adhesive where the first and second portions can be positioned proximate to one another,
wherein, when the micro heaters are no longer energized, the temperature sensitive adhesive transitions to a second less pliant bonding state to secure the first portion and the second portion, and
wherein the micro heaters are configured to be subsequently re-energized to return the temperature sensitive adhesive to the relatively pliant state so that the first portion can be separated from the second portion,
the micro heaters comprising conductive nanoparticles or the micro heaters being patterned on a carrier tape.
2. The device of claim 1 , the micro heaters comprising conductive nanoparticles.
3. The device of claim 1 , the micro heaters being patterned on a carrier tape.
4. The device of claim 3 , the micro heaters comprising conductive wires adhered to the carrier tape.
5. The device of claim 3 , the micro heaters being positioned on only a single side of the carrier tape.
6. The device of claim 3 , the micro heaters being positioned on opposite sides of the carrier tape.
7. A device comprising:
a first portion and a second portion, the second portion comprising a display area and a bonding area;
a sensor mesh positioned between the first portion and the second portion; and
a bonding assembly configured to bond the first portion to the second portion within the bonding area, the bonding assembly comprising:
a temperature sensitive adhesive positioned between the first portion and the second portion within the bonding area, and
micro heaters positioned on one or more sides of the sensor mesh within the bonding area, the micro heaters configured to be selectively energized to transition the temperature sensitive adhesive from a bonding state to a relatively pliant state.
8. The device of claim 7 , the micro heaters being positioned on only one side of the sensor mesh.
9. The device of claim 7 , the micro heaters being positioned on opposite sides of the sensor mesh.
10. The device of claim 7 , further comprising sensor traces positioned on the sensor mesh within the display area.
11. The device of claim 7 , the bonding assembly forming a flexible printed circuit.
12. The device of claim 11 , the device being flexible.
13. The device of claim 12 , the first portion or the second portion comprising an organic light-emitting diode display.
14. The device of claim 7 , the device comprising a component of a wearable device.
15. The device of claim 14 , the wearable device being a flexible wrist-worn device.
16. A device comprising:
a display portion having a display area and a bonding area;
another portion;
a sensor mesh comprising sensor traces positioned relative to the display area and micro heaters positioned relative to the bonding area; and
an adhesive positioned relative to the bonding area, the micro heaters being configured to transition the adhesive to different states including a bonding state where the adhesive secures the display portion to the another portion and another state where the display portion is removable from the another portion.
17. The device of claim 16 , the micro heaters further configured to heat the adhesive to transition the adhesive from the bonding state to the another state.
18. The device of claim 17 , the micro heaters further configured to perform a secondary functionality comprising dissipating electrical charge of the device.
19. The device of claim 16 , the sensor traces and the micro heaters comprising conductive metal traces, graphene, or another organic compound.
20. The device of claim 16 , the bonding area forming a periphery around the display area.
