Tests were conducted to determine the optimum sputtering conditions for which the strongest metallization adherence could be achieved for the ferrite safing wheel assemblies. The conditions were varied through four separate test runs with a fifth verification run conducted using parameters selected from the first four runs. The parameters tested were the effects of etching, precleaning, chamber pressures, plating materials, plating thickness, soldering pressures, and cooling rates. The results increased the strength of the metallization to two pounds, well in excess of the required one pound minimum. It was also determined that the gold should be sputtered on and not thermally deposited, which caused cracking in the ferrite material.
