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.
