Abstract:
1. A method of soldering a metallized fiber to a metal bond pad, the method comprising: providing a stacked resistor structure having first and second layers beneath the bond pad with the first layer lying directly beneath the bond pad having a higher relative resistance than the second layer, the stacked resistor structure, when subjected to a current flowing generally along a first axis, being characterized by a temperature profile that has first and second peaks on either side of the bond pad where the first and second peaks are disposed relatively closer to the bond pad than to a source of the current; disposing a solder perform over the bond pad; disposing the metallized fiber over the bond pad with the fiber extending along a second axis in the region of the bond pad, the second axis being as a non-zero angle with respect to the first axis; and flowing a current through the stacked resistor structure.
