ABSTRACT:
A method of forming a conductive connection between predominantly miniature members by pressing the members together and heating by means of electrodes through which three successive pulses of electric current are passed. First and second pulses act to break a flowable insulation coating of one of the members, melt a solder alloy in the location of the connection and effect a weld, while a third current pulse is applied to the electrodes prior to their raising from the members to thereby melt the solder alloy and flowable insulation coating, whereafter the electrodes are withdrawn from the members and the third current pulse is quenched.
