Abstract
An improved leadform for use with surface mount components is described. The improved leadform provides a connection to a printed circuit substrate which is highly resistant to stress related failures. The leadform is configured so that the connection utilizes a relatively greater area of the leadform for contact with a solder connection resulting in a more compliant connection. In addition, the present invention provides a preparation for the printed circuit media which allows the substrate media to absorb stresses which occur due to thermal cycling.
