  • Publication number: 20080152815
    Abstract: A self-healing coating, incorporating medium-sized microcapsules filled with a liquid formulation, repairs itself upon physical compromise. In one embodiment, a commercial primer is mixed with these microcapsules and applied. After the coating has cured, any physical compromise of the cured coating results in the microcapsules bursting to release the liquid, in turn filling and sealing the compromised volume of the coating. In applications where a product is used to provide corrosion protection, the liquid contains anti-corrosion material as well as suitable diluents and film-forming compounds. In a preferred embodiment, the microcapsules are provided separately to be mixed with commercial products during preparation for application of the coating. For example, if a paint formulation is known a priori, tailored microcapsules packaged separately from the paint and designed for use with the paint formulation, are wet mixed into the paint during preparation for application.

  • Patent number: 7004375
    Abstract: The present invention relates to a pressure sensitive fluxing underfill composition that may be pre-applied to electronic components, such as CSP's, in order to increase the reliability of the component against mechanical stresses such as impact and bending. The composition contains an epoxy resin, a solid anhydride curing agent, and catalyst. Other materials, such as air release agents and fillers, may also be added as desired. The composition may be applied selectively to parts of the CSP, for example to the solder bumps. The composition provides sufficient tack in order to hold the electronic assembly together during the assembly process.

  • Patent number: 6890592
    Abstract: The present invention teaches an improved process for preparing a population of microcapsules having a substantially uniform size distribution, especially useful for manufacture of carbonless paper. The improved process teaches use of membrane material having a pre-selected pore size in the capsule manufacture process. A core material is provided along with a receiving solution for receiving the core material. The receiving solution is a nonsolvent for the core material. The core material is passed under pressure through the membrane into a moving or turbulent receiving solution forming uniform droplets of core material dispersed in the receiving solution. Wall-forming material is added to the receiving solution for coating the core material droplets. The coating on the droplets is polymerized forming microcapsules. This novel process also lends itself to microcapsule formation in a continuous process.

  • Patent number: 6831116
    Abstract: Novel modifying agents contain a sharply-melting crystalline polymer ingredient, preferably a side chain crystalline (SCC) ingredient, and an active chemical ingredient. Such modifying agents, especially when in the form of particles, can be placed in contact with a matrix, will not modify the matrix below the crystalline melting point Tp, but will rapidly modify the matrix above Tp. The active chemical ingredient can react with the matrix, catalyze a reaction of the matrix, or inhibit a reaction of the matrix. Particularly useful compositions are polymer precursors which are storage-stable at low temperatures but which are rapidly converted to crosslinked resins when heated to temperatures above Tp, optionally in the presence of light.

  • Publication number: 20040234763
    Abstract: This invention provides a mounting method for reliably connecting mounting components electrically. Specifically, an anisotropically conductive adhesive can be composed of crushable microcapsules and a second liquid in which the microcapsules are dispersed. Each microcapsule encloses a first liquid and a conductive particle. The first liquid can react with the second liquid at normal temperatures to cure the second liquid. This anisotropically conductive adhesive can be applied on a flexible printed circuit (FPC). Then, a drive IC is mounted and pressed on the FPC to crush the microcapsules between electrode pads provided on the drive IC and electrode pads provided on the FPC, thereby bonding the electrode pads. Subsequently, the anisotropically conductive adhesive is heated to plasticize a capsule wall of each microcapsule, thereby bonding the drive IC and the FPC.

  • Patent number: 6822341
    Abstract: A latent catalyst particularly useful in epoxy molding compositions for use in electronic packaging materials is provided. The latent catalyst is in the form of a curative represented by a combination of an inorganic-based carrier having an activated surface and a catalyst compound including a moiety capable of accelerating curing of the epoxy resin, such as the reaction product of silica and 1,8-diazobicyclo(5.4.0)undecene-7 (DBU). The activated surface of the inorganic-based carrier includes reactive surface groups capable of bonding to the moiety through a hydrogen bond, and also includes a high surface area porous surface, such that the catalyst compound is sorbed on the activated surface. The invention further provides epoxy compositions including the curative with an epoxy resin and a curing agent for the epoxy resin, which compositions are particularly useful as molding powders for semiconductors with prolonged shelf life stability.
