Abstract
Resistors can be screen printed onto a green tape stack from a resistor ink comprising ruthenium oxide and a sufficient amount of a low melting temperature glass so that the resultant mixture fires at a temperature of 850-900° C. A conductive layer, as of silver, terminates the screen printed resistor layer and one or two green tapes are applied over the resistor layer to embed the resistors during firing. A final conductive layer is applied after firing.
