Improved LHE ZN-NI and CD Plating Process

Abstract

The overall objective of this SBIR Phase II project was to reduce the HE relief bake time requirement after the electroplating process. This objective was met by performing the sustained load, ISL, TDS and LECO tests mentioned above. Test subjects were prepared IAW their respective standards, drawings, and ASTM F519: Standard Test Method for Mechanical Hydrogen Embrittlement Evaluation of Plating/Coating Processes and Service Environments. To achieve the desired results, the measurement in the reduction of time required to pass accepted hydrogen embrittlement tests was correlated to the amount of hydrogen that was in the coupon which was measured by TDS, and LECO.
