ABSTRACT:
A system and method are described for manufacturing a lapping plate. Diamond particles are premixed with a metal matrix. The diamond particles are electro-deposited onto the surface of a lapping plate. The lapping plate may have a substrate of hard metal with a soft metal coating. The metal matrix and the lapping plate may be the same metal. The metal matrix may be tin, copper, nickel, or silver. The metal matrix may be an alloy of tin, copper, nickel, or silver. The diamond particles may be between 0.1 and 0.25 microns in size. Multiple uniform layers of the diamond particles and metal matrix may be stacked on the lapping plate.
