Abstract:
Resin particles comprised of an acrylic resin. Not only is the maximum compression deformation ratio thereof as great as 60% or more but also the load required for 60% compression deformation is as small as 60 mN or less. Wiring boards are therefore coupled in using an anisotropic conductive adhesive obtained by first manufacturing conductive particles having a conductive coating formed on a resin particle surface of the resin particles by adhering a conductive material to the surface of the above resin particles as a core. On dispersing the conductive particles in an adhesive material, the conductive particles sandwiched between metallic wires of the wiring boards are greatly deformed by a small load, so that the electrical devices having a high conduction reliability can be obtained.

The device comprises a liquid crystal panel and an auxiliary panel formed with an IC circuit for supplying driving signals to the liquid crystal device. The auxiliary substrate is separately provided with the circuit and the function thereof is tested in advance of the assembling with the liquid crystal panel. By this procedure, the yield is substantially improved.

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. The beads in the adhesive can form a monolayer between the read/write head and the suspension such that a spacing therebetween is equal to the average diameter of the beads. The metal coating of the beads provide electrical conductivity between the read/write head and the suspension.

A plasma display device may include a plasma display panel, a driving circuit portion for driving the plasma display panel, a connecter for electrically connecting electrodes of the plasma display panel with the driving circuit portion, and an interconnecter for electrically connecting the connecter with the plasma display panel. The interconnecter may include an adhesive layer, a plurality of conductive pellets, and a plurality of non-conductive pellets dispersed in the adhesive layer. The conductive pellets may be positioned substantially within a first region where the wiring of the connecter overlaps the electrodes of the plasma display panel. The non-conductive pellets may be positioned substantially at least at a second region other than the first region in the adhesive layer.

Abstract:
A conductive particle used for an anisotropic conductive adhesive provides an anisotropic conductive bonding between terminal electrodes without deforming a wiring pattern or the terminal electrode of a circuit board. A conductive layer is formed on a surface of a core particle of the conductive particle. The conductive particle has a yield point within a range of degree of deformation from 5% to 40% so that a modulus of compressive deformation of the conductive particle drastically increases at the yield point.
