ABSTRACT:
A voice coil and actuator yoke assembly is fabricated by deforming the coil to exactly fit the inner perimeter and thickness of the yoke. The comb is placed in a tool that registers the comb with the yoke against the same flat surfaces that will squash the coil. The tooling is closed and placed in an appropriate loading device and the coils are squashed to the precise thickness of the yoke. This eliminates the in-plane tolerances of the current process for bonding a coil into the yoke. The coil perimeter expands as the coil is squashed to form an intimate press fit with the yoke. A low viscosity, high Tgadhesive is then applied to the coil. The low viscosity of the adhesive allows capillary action to fill the voids between the wires and bond the coil to the yoke.
