Abstract
Fine copper and nickel powders are well mixed in a preselected ratio with bonding agents and carriers as appropriate. The composition then may be patterned upon a substrate by screen printing and subsequent firing in a nitrogen atmosphere to produce a low sheet resistance, low TCR electrical resistor. Various alloy powders, inert materials, and glass frits may be used depending upon the desired characteristics.
