Notable Features: 
  • Copper Core is needed to elevate the electrical conductivity of the terminal. The nickel/iron alloy will operate as an expansion alloy for sealing purposes and the small copper core will provide higher current capabilities.
  • Spherical radius on one end.
  • Wire bondable flat on the other end.
  • Formed from wire with no scrap developed.
  • The flat is very uniform and presents an exceptional wire bond surface. The surface finish will be integral across both the nickel/iron surface as well as the copper surface-without showing any separation between the two metals.
  • The corner (or edge) break at the end of the flat has a radius of .001" max. good for wire bonding near the edge of this feature-which provides a large target for bonding.
  • Very good finish on spherical radiused end. No machining lines.
