  • Publication number: 20150034241
    Abstract: Provided are adhesive articles and assemblies that include a flat and at least partially elastic backing along with a patterned adhesive coating on each side of the backing. When viewed from directions perpendicular to the backing, the adhesive on one side of the backing does not substantially overlap the adhesive on the opposing side of the backing. As a result, it is possible to use a stretch removable adhesive article that uses, for example, an aggressive adhesive to provide a reliable bond but still remove cleanly and easily from delicate substrates that would otherwise be damaged or destroyed if bonded with conventional adhesive constructions.

  • Publication number: 20140116615
    Abstract: An adhesive composition according to the present invention contains a polymerizable group-containing siloxane compound, a polymerization initiator and an ultraviolet-absorbing blowing agent. This adhesive composition enables quick bonding of substrates etc. by light irradiation or by heating such that the bonded substrates can secure adhesion and heat resistance to withstand grinding etc. and, when no longer needed to be bonded, can be easily separated from each other by ultraviolet light irradiation and is thus suitable for use as an adhesive composition for manufacturing of semiconductor devices (particularly for manufacturing of semiconductor devices with through-silicon vias).

  • Patent number: 8435376
    Abstract: Disclosed herein is a carrier for manufacturing a substrate, including: a base plate; adhesive layers formed on one side or both sides of the base plate; auxiliary adhesive layers, each of which is buried in one side of each of the adhesive layers, has a smaller area than each of the adhesive layers and has lower adhesivity than each of the adhesive layers; and metal layers, each of which is formed on one side of each of the auxiliary adhesive layers, whose edges are attached to the adhesive layers, and whose other portions excluding the edges are attached to the auxiliary adhesive layers. The carrier is advantageous in that a metal layer and an auxiliary adhesive layer are attached to each other by the adhesivity of the auxiliary adhesive layer, so that it is not required to use vacuum adsorption, with the result that a process of manufacturing a substrate can be performed more stably.

    Abstract: A label for removable application to an article such as a beverage bottle includes a backing layer (2) comprising a laminate of a bi-axially oriented polyester such as PET (12) and a bi-axially oriented polypropylene (14). The polyester film (12) has a lower coefficient of thermal expansion than the polypropylene film (14). Consequently, when the label is heated, it will tend to curl and this effect can be used to assist in the removal of the label from the article in a hot washing bath during recycling of the article.

  • Patent number: 8303752
    Abstract: Provided is a method of manufacturing a wiring board, in which: a composite adhesive sheet 20 is attached to one of the surfaces of a support substrate 10, and a double-sided CCL 30 is attached to the other surface. Then, in an integrated state of the above components, a multilayer wiring structure including a conductive layer and a resin insulating layer is formed on a metal layer 33 of the double-sided CCL 30 by a known build-up method. A thermally foamable adhesive layer 22 of the composite adhesive sheet 20 is then heated, thereby thermally decomposing a thermal foaming agent to generate gas, and the support substrate 10 is separated from the remaining bonded body. Thereafter, a carrier foil layer 32b and a copper foil layer 32a of a carrier-foil coated copper foil 32 are mechanically peeled from each other at a boundary between both the layers, thereby obtaining a wiring board 1.

  • Patent number: 8092645
    Abstract: During detachment of a die from an adhesive tape, the inner and outer portions of a first side of the die which is in contact with the adhesive tape is supported with a support surface. A collet contacts the inner and outer portions of a second side of the die opposite to the first side. Support is withdrawn from the outer portion of the die such that the outer portion of the second side of the die bends away from the collet while the support surface only supports the inner portion of the die. Vacuum suction from the collet is applied to attract the outer portion of the die towards the collet and the vacuum suction pressure is monitored until a threshold pressure is reached indicating that the outer portion of the die is contacting the collet. Thereafter, the collet is lifted while holding the die with vacuum suction to completely separate the die from the adhesive tape.

The projection screens additionally provide improved light control for enhanced brightness, uniformity, and contrast for both 2D and 3D systems. Generally, the disclosed method for providing a projection screen comprises stripping an optically functional material from a carrier substrate, thus creating engineered particles from the optically functional material. The engineered particles may then be deposited on a second substrate to create a substantially homogeneous optical appearance of the projection screen.

  • Patent number: 5948507
    Abstract: Absorbent articles containing absorbent cores of fluff pulp frequently contain wrinkles in the absorbent core that run from side to side of the article, typically normal to the machine direction in the manufacturing process. Side-to-side wrinkles are deleterious in that they provide large flow channels for urine or other body fluids to escape to the edge of the article. Frequently, such wrinkles are present after manufacturing, before the article has been folded or worn. The cause of the wrinkles is believed to be due to natural instabilities during compression of the fluff pad shortly after it is formed. Means for reducing cross-directional wrinkles include the use of grooved, drilled, or patterned compression rolls to densify the fluff pulp while providing opportunities for reduced in-plane displacement during compression or, if in-plane displacement does occur, providing paths for cross-directional displacement as well as machine-direction displacement so that continuous CD wrinkles cannot form.
