  • Patent number: 5820716
    Abstract: A method for surface mounting electrical components to a substrate, such as a printed circuitboard, involves use of an anisotropically conductive adhesive or Z-Axis adhesive between facing conductive surface areas on the component and substrate. Pressure is applied to the conductive adhesive by a nonconducting adhesive that is first cured between oppositely facing nonconductive surface areas of the component and substrate. This fixes the thickness of each layer of the conductive adhesive at a dimension no greater than its design conductive thickness. In a first submethod, the nonconducting adhesive is a fast setting adhesive subjected to mechanical pressure only as it is assembled on the substrate prior to the subsequent curing of the conductive adhesive. In a second submethod, it is a high shrinkage adhesive that applies compressive force between the component and substrate as it cures and shrinks dimensionally while at a temperature below the subsequent curing temperature of the conductive adhesive.

  • Patent number: 5733402
    Abstract: In the production of electrically insulated coils which make up insulating layers, insulating material is wound around an electric conductor to form an insulating substrate, then impregnating varnish consisting of thermosetting resin is applied to the insulating substrate and hardened. In this electrically insulated coil production method, the impregnating varnish is made up of acid anhydride setting epoxy resin elements that include latent accelerators. These accelerators take more than 30 days to increase their initial viscosity by three times during storage at 25 degrees centigrade. After the insulating substrate is impregnated with the varnish, the substrate is heated at a temperature which will cause the impregnating varnish on the surface of the insulating substrate to lose its fluidity in under 30 minutes in order to preset the varnish.

    Abstract: A substantially cylindrical bar of microporous PTFE is non-fibrillated and incorporates pores within any cylindrical surface within the bar centred about the central longitudinal axis of the bar that are of substantially uniform size and are substantially uniformly distributed within that surface. The process for producing such a bar includes the step of applying a substantially radial compressive force to pre-heated and cooled granules of PTFE and subsequently re-heating and cooling the compressed granules, while a film of non-fibrillated, microporous PTFE is formed from the cooled bar, the plane of the film being perpendicular to the direction of the radial compressive force whereby the pores within any plane substantially perpendicular to the thickness of the film are of substantially uniform size and are substantially uniformly distributed within that plane and all such parallel planes.
