Abstract:
1. A method for reducing heat absorption around solder pads on an electrical lead suspension (ELS) comprising: providing a base-metal layer having at least one opening; providing a dielectric layer above the base-metal layer, said dielectric layer covering a portion of said base-metal layer and the at least one opening in said base-metal layer; providing a signal conductive layer above the dielectric layer, said signal conductive layer comprising: placing said solder pad portion comprised only from said signal conductive layer above said portion of said dielectric layer such that said solder pad portion is adjacent to, but does not align with the at least one opening in said base-metal layer, wherein during reflow of a solder on said solder pad the heat absorption with respect to said base-metal layer is reduced.
