An interfaced carrier assembly including an interface circuit having printed contacts to provide electrical interface or feedback control for lapping operations. The printed contacts are formed on a base material on the interface circuit and interface with terminal pads on a slider bar supported by a carrier plate for lapping feedback control. The interface circuit is assembled with the carrier plate with contacts on the interface circuit aligned with terminal pads on the slider bar supported by the carrier plate. Alignment of the terminal pads on the slider bar and contacts on the interface circuit are measured by digital cameras for assembly of the interfaced carrier assembly.

Interface assembly for lapping control feedback

An actuator adapted to adjust the profile of a carrier supporting a bar relative to a lapping surface. The carrier including a plurality of spaced control or actuation points along the length of the carrier for adjusting the profile of the mounting surface of the carrier adapted to support a bar for lapping. The actuator adapted to actuate the carrier at the spaced actuation points and including a plurality of actuation members movably actuated via pressure supplied to the actuation members. The actuation members are supported in spaced staggered relation in chambers in a manifold for bidirectional actuation. The actuation members are spaced relative to the spaced actuation points and are supported relative to the manifold to provide precision actuation for incrementally adjusting the profile of the carrier.
