    Abstract: An electrically conductive adhesive includes a resin component, a photoinitiator, and metal-coated polymer beads. The beads have an average diameter and a very narrow size distribution around the average diameter. The adhesive is applied between a read/write head and a suspension to attach the two, and the adhesive is cured by exposure to an illumination and/or heat. A pad spacer is included between the read/write head and the suspension to define a spacing and parallelism therebetween. The beads in the adhesive can form one or more layers between the read/write head and the suspension or can be disordered. The metal coating of the beads provide electrical conductivity between the read/write head and the suspension.

    Abstract: The invention provides a composition comprising: (i) a ferrofluid comprising a colloidal suspension of ferromagnetic particles in a non-magnetic carrier liquid, and (ii) a plurality of electrically-conductive particles having substantially uniform sizes and shapes, dispersed in the ferrofluid. Various types of substantially non-magnetic electrically-conductive particles are described. Application of a substantially uniform magnetic field by magnet means to the composition causes the electrically-conductive particles to form a regular pattern. The composition is used for providing anisotropic conductive pathways between two sets of conductors in the electronics industry. The composition may be a curable adhesive composition which bonds the conductors. Alternatively or in addition the electrically-conductive particles may have a latent adhesive property e.g. the particles may be solder particles. The ferrofluid may be a colloidal suspension of ferromagnetic particles in a liquid monomer.

    Abstract: In a conductive connecting structure for electrically connecting first and second electronic parts each having a plurality of connecting terminals arranged at a small pitch, a conductive bonding agent is interposed between the plurality of connecting terminals of the first and second electronic parts. The conductive agent is prepared by mixing a plurality of fine connecting particles in an insulating adhesive. Each fine connecting particle is designed such that a fine conductive particle or a fine insulating particle with a plating layer formed on its surface is covered with an insulating layer consisting of a material which is broken upon thermocompression bonding. When the conductive bonding agent is subjected to thermocompression bonding between the connecting terminals of the first and second electronic parts, portions of the fine connecting particles which are urged by the respective fine connecting terminals are broken. However, the insulating layers of the fine connecting particles in the planar direction are not broken and remain as they are. In this conductive connecting structure, even if the ratio of fine connecting particles is increased, and adjacent fine connecting particles are brought into contact with each other, insulating properties can be kept in the planar direction, while conduction is obtained only in the direction of thickness.

    Abstract: A light source and method for making the same are disclosed. The light source includes a plurality of surface mount LEDs that are bonded to a mounting substrate by a layer of asymmetric conductor. Each LED has surface mount contacts on a first surface thereof and emits light from a second surface thereof that is opposite the first surface. The mounting substrate includes a top surface having a plurality of connection traces. Each connection trace includes an n-trace positioned to underlie a corresponding one of the n-contacts and a p-trace positioned to underlie a corresponding one of the p-contacts, the p-trace having an area greater than the p- contact. The layer of asymmetric conductor is sandwiched between the surface mount contacts and the connection traces, and can optionally extend into the spaces between the LEDs to provide a scattering medium for redirecting light leaving the sides of the LEDs.
