ABSTRACT:
A system and a method for bonding a slider to a suspension tongue are disclosed. A set of conductive fibers is embedded in a bonding adhesive binding the slider to the suspension tongue to improve conductivity between the slider and the suspension assembly. The bonding adhesive includes binder resin and silver powder. The slider is composed of aluminum oxide and titanium carbide. The set of conductive fibers is composed of carbon coated potassium titanic acid whisker. The set of conductive fibers range in length from 10 μm to 20 μm, and in diameter from 0.3 μm to 0.6 μm. The set of conductive fibers range in resistance from 0.01 ohm to 0.1 ohm. The set of conductive fibers is mixed with the bonding adhesive in a 1% to 4% mixing ratio.
