Abstract
A method of securing a metal lead of a polymer battery to a flexible circuit, comprising the steps of positioning a metal lead of a polymer electrolyte battery onto a connection pad of a circuit; clamping the metal lead and the connection pad between two weld fixtures of an ultrasonic welder; compressing the metal lead and connection pad between the two weld fixtures to establish a pressure of about 44.9 psi to about 30.8 psi; and vibrating the weld fixtures at a frequency of about 20 kHz for about 0.1 seconds to about 2.0 seconds.
