Abstract
A suspension assembly used in magnetic disk drives includes a load beam and a gimbal assembly coupled to an end of the load beam. The gimbal assembly includes a support having a left outrigger and a right outrigger, first tethers or connectors disposed along the left outrigger, second tethers or connectors disposed along the right outrigger, and a flexible circuit assembly that includes a left electrical trace and a right electrical trace. The flexible circuit assembly is coupled to the support through the first tethers or connectors that couple the left electrical trace to the left outrigger and the second tethers or connectors that couple the right electrical trace to the right outrigger. The first and second tethers or connectors are made of stainless steel with a polyimide coating and there are three first tethers or connectors and three second tethers or connectors.
