Abstract
A solder terminal strip stamp formed from thin metal stock includes a carrier strip, a plurality of solder terminals extending to one side of the carrier strip and reverse bend the contact arms on the ends of the terminals away from the strip. A thin solder layer is integrally bonded to contact arm and is joined to solder reservoirs located on the sides of the arms.

- i) a second contact tail extending away from the carrier strip to an end remote from the carrier strip,
- ii) a second arm located a distance away from the carrier strip and to one side of the second contact tail,
- iii) a second contact base on the second arm facing away from the second contact tail and,
- iv) a reverse bend portion integrally joining said second contact tail and second arm so that the arm overlies a portion of the contact tail and the second contact base faces away from such tail;
- and
- D) an integral solder mass comprising a thin solder layer integrally bonded to the second contact base, a solder reservoir extending along an edge of the contact base and joined to the thin solder layer and a solder recess located on a side of the second arm facing the second contact tail.
