  • Multiple wire photosensitive adhesive for wire embedment
    Patent number: 4855333
    Abstract: A high density dimensionally stable encapsulated wire circuit board and a method of making such a board is described. A photo-curable adhesive having a unique combination of rheological properties is utilized to bond insulated wires to a substrate. The unique combination of rheological properties of the adhesive used in the encapsulated wire circuit boards of this invention include a specified range of values for the Storage Shear Modulus and specified range of values for the Loss Angle ratio.A new photo-curable adhesive having these properties and a method of obtaining such an adhesive are also described.

  • Method and composition for applying coatings on printed circuit boards
    Patent number: 4479983
    Abstract: A coating is produced by a method including a screen printing of a photopolymerizable composition on a printed circuit board, illuminating said composition to partially polymerize it and bake it to complete the polymerization.The composition used by said method contains a reaction product of a monoethylenically unsaturated carboxylic acid with a material of the group of epoxy resin and epoxidized novolak, a phenoxy resin, a thickening agent, a polyethylenically unsaturated compound, a photo-initiator and a solvent.The coating produced according to this invention is used as solder mask.
