  • Patent number: 9456508
    Abstract: Assemblies of structures such as electronic device assemblies may be connected using light-cured liquid adhesive such as ultraviolet-light-cured adhesive. Light sources such as ultraviolet-light light-emitting diodes may be mounted to a substrate such as a printed circuit board substrate. The substrate may be mounted to an assembly formed from a plurality of structures. The structures may be connected to each other to form an interior cavity within which the substrate and light-emitting diodes are contained. A connector may be included in the assembly. The connector may have input-output pins. Conductive paths may couple the input-output pins to the light-emitting diodes in the cavity. A tool may be used to apply signals to the light-emitting diodes to activate the light-emitting diodes. The light-emitting diodes produce light that cures the adhesive. The light-emitting diodes may be disabled by blowing a fuse after the adhesive has been cured.

    Abstract: Removable mask films 303 are formed on the both sides of the substrate having the adhesive layer 302 by applying and drying a resin varnish 304 including a ultraviolet-absorbing agent, and fine through holes 306 are formed by using a third harmonics YAG solid-state laser light with a relatively short wavelength not longer than that in the ultraviolet range in such a way that the effects of such a residual strain as the conventional embodiment forming a removable mask film by a laminating process may be decreased as well as the more fine hole drilling compared with conventional embodiment using the carbon dioxide gas laser with a relatively long wavelength may be performed.

  • Patent number: 6472025
    Abstract: A method of producing a coating of solvent-free pressure-sensitive adhesive systems on substrates, especially release-coated substrates, in which the pressure-sensitive adhesive system is applied in one or more layers to a rotating roller by means of an adhesive applicator, the pressure-sensitive adhesive system on the roller is crosslinked in an irradiating means by means of high-energy radiation, and the roller is contacted with the substrate, so that the pressure-sensitive adhesive system is transferred from the roller to the substrate.

  • Publication number: 20020155243
    Abstract: An adhesive article including a liner having a first side and a second side; and an adhesive having a first surface and a second surface, wherein the second surface of the adhesive contacts the first side of the liner, wherein the article has been exposed to E-Beam radiation through the second side of the liner, and wherein the article has been wound upon itself causing the second side of the liner to come into contact with the first surface of the adhesive, and wherein the second side of the liner to the first surface of the adhesive have a release value that is less than the release value of the first side of the liner to the second surface of the adhesive. A method of producing an adhesive article including the steps of applying release coating compound(s) to a second side of a liner backing; applying an adhesive onto a first side of said coated liner backing; crosslinking said adhesive with E-Beam radiation applied through the second side of said liner backing; and winding said article into a roll.

  • Patent number: 6284328
    Abstract: Process for producing adhesive tapes in which adhesive tapes coated on one side with an adhesive composition are subjected to radiation crosslinking, the irradiation of the adhesive tape taking place through the backing material of the adhesive tape onto the adhesive composition in such a way that the backing material and that side of the adhesive composition facing the backing material receive a dose of from 30 to 200 kGy, in particular 100 kGy, and the acceleration voltage during the irradiation being chosen such that the dose on the open side of the adhesive composition has fallen from 0 to 60 kGy, in particular from 10 to 20 kGy.

  • Patent number: 6242504
    Abstract: A description is given of a method of crosslinking radiation-crosslinkable pressure-sensitive adhesive films by controlled-dose exposure to actinic radiation, which involves exposing the film surface to a regular or irregular radiation pattern made up of regions of different intensity. The method permits a more precise adjustment of the adhesion—in particular, the adhesion of flexible films on a substrate.
