  • Patent number: 9272431
    Abstract: A method is provided for removing a polarizing sheet with a tool that includes a handle including a main body forming therein a channel for receiving adhesive dissolving liquid, a piston device mounted inside the channel, and a guide tube mounted on the main body, and a blade mounted to the handle. The guide tube has an end in communication with the channel and an opposite end positioned on the blade to guide the adhesive dissolving liquid from the channel to the blade. The polarizing sheet is removed by lifting up a portion of the polarizing sheet and placing the blade against bonding adhesive between the polarizing sheet and a substrate to which the polarizing sheet is attached to allow the adhesive dissolving liquid to be guided by the guide tube toward the blade for subsequently flowing toward and dissolving bonding adhesive.

    Abstract: Described methods and apparatus provide a controlled perturbation to an adhesive bond between a device wafer and a carrier wafer. The controlled perturbation, which can be mechanical, chemical, thermal, or radiative, facilitates the separation of the two wafers without damaging the device wafer. The controlled perturbation initiates a crack either within the adhesive joining the two wafers, at an interface within the adhesive layer (such as between a release layer and the adhesive), or at a wafer/adhesive interface. The crack can then be propagated using any of the foregoing methods, or combinations thereof, used to initiate the crack.

  • Publication number: 20110253316
    Abstract: Embodiments of the invention are used to provide ways of tire tread molding and retreading with a double tread rubber body having a unitary structure that comprises two treads in order to remove the need for buffing an oxide layer typically associated with tread molding and curing. Embodiments of the double tread molding and retreading methods also remove the need for cementing the cured tread to prevent future oxidation buildup. Once the double tread is cured and cooled, it is cut along the centerline with a double tread separation apparatus to expose a soft non-oxidized inner rubber. The cutting is much less energy intensive when compared to buffing with an expendable wire brush. There is no risk of spots of oxidized rubber being missed as is the case with buffing. There is little or no dust created.
