#25- The Influence of Stamping Die Design on the Selectivity of Electroplated Coatings on Connector Contact Surfaces
Abstract: In order to achieve low manufacturing and low material costs for high reliability connectors, stamping throughput must be maximized and precious metal content must be minimized. Using a dual beam connector as the model, conventional stamping lay-out methods and their impact on the ability to selectively apply precious metal coatings are discussed in this Materion Technical Materials paper.
Alternative Stamping Lay-Out
It is found that the conventional lay-out results in a compromise between high throughput and precious metal consumption. An alternative lay-out is then presented which lends itself to both high stamping throughput and a new, highly selective plating technology. The shortcomings of the conventional lay-out are overcome resulting in maximum stamping throughput and minimum precious metal consumption.
