Patent ID: 8289651

Claim:
An apparatus comprising: an armature arm having a first and an opposite second side; a printed circuit board (PCB) having a first and an opposite second side, wherein the first side of the PCB is secured to at least a portion of the first side of the armature arm, wherein the PCB includes: an integrated circuit (IC) seat that includes a plurality of writer head seats, wherein the IC seat is located on the second side of the PCB, wherein the IC seat is substantially rectangular having a first side, a second side, a third side and a fourth side, and wherein the first and second sides are substantially parallel to one another, and wherein the third and fourth sides are substantially parallel to one another, and wherein each writer head seat has a first dimension and a second dimension; a ground plane that underlies at least a portion of the IC seat; and a plurality of circuit traces, wherein at least one trace is in electrical contact with the ground plane; an IC that is substantially aligned with the IC seat, wherein the IC seat includes a plurality of writer heads, wherein each writer head is substantially aligned with at least one of the writer head seats; a first set of solder bumps that are secured to the IC and the PCB such that the IC is in electrical contact with the wound plane, wherein a first subset of solder bumps from the first set of solder bumps located along the first side of the IC seat, and wherein a second subset of solder bumps from the first set of solder bumps is located along the second side of the IC seat; and a plurality of second sets of solder bumps, wherein each solder bump from each of the second sets of solder bumps is secured to the IC and the PCB, wherein each second set of solder bumps is associated with at least one of the writer head seats, and wherein each solder bump from each of the second sets of solder bumps is positioned to be less than the first dimension of each write head seat from at least one of the solder bumps from the first set of solder bumps.
