Abstract:
An apparatus and method for reducing heat absorption around solder pads on an electrical lead suspension (ELS). The method provides a base-metal layer having at least one opening. A dielectric layer is also provided above the base-metal layer, the dielectric layer covering a portion of the base-metal layer and at least one of the openings in the base-metal layer. A signal conductive layer is provided above dielectric layer. The signal conductive layer carries at least one solder pad portion, wherein the solder pad portion is placed above the portion of the dielectric layer such that the solder pad portion does not align with the at least one opening in the base-metal layer. In so doing, the heat absorption with respect to the base-metal layer is reduced.
