Abstract:
1. An electronic component package comprising: a substrate comprising a first surface; a first trace on the first surface, the first trace extending in a longitudinal direction, the first trace having a first latitudinal width in a latitudinal direction, the latitudinal direction being perpendicular to the longitudinal direction; an electronic component comprising a bond pad; a copper pillar attached to the bond pad, the copper pillar having a longitudinal length and a second latitudinal width, wherein the longitudinal length of the copper pillar is greater than the second latitudinal width of the copper pillar, the second latitudinal width of the copper pillar being equal to and aligned with the first latitudinal width of the first trace, the longitudinal length of the copper pillar being parallel with the longitudinal direction of the first trace and being in line with the direction of maximum stress between the electronic component and the substrate; and a solder joint mounting the copper pillar to the trace.
