Abstract
Abstract The prior art terminal for making a solder bond between a lead and a bond site is modified so as to enhance the reliability of the solder bond. In one embodiment, this modification entails solder relief terminals: solder relief holes through the terminal, notches, grooves or ridges on the surface of the terminal, or bending of the terminal. In a second embodiment, this modification entails predeposit of a predetermined and controlled amount of solid solder and flux on the terminal.
