Claim 6:
7. An apparatus, comprising:
a substrate having at least one conductive trace layer and an adjacent dielectric layer, the at least one conductive trace layer comprising multiple conductive traces of a thickness respectively terminating at associated terminal pads integral with metal material of the conductive traces; and
at least one terminal pad having an irregular surface topography comprising:
at least one protruding portion of a same thickness as a thickness of a respectively associated conductive trace and comprising:
a peripheral protruding portion; and
multiple, mutually laterally spaced protruding portions laterally inwardly spaced from the peripheral protruding portion, the multiple, mutually spaced protruding portions configured as pillars and separated from the peripheral protruding portion by one or more recess portions; and

at least one recess portion extending into the terminal pad at least to a depth proximate the dielectric layer.
