Fabrication of thick film electrical components

Abstract

A thick-film resistor component (1A, 50) may include a thick film component (1A, 54) formed between a thick-film resistor (1A, 60) and an electrically conductive sheet (1A, 52), wherein a portion of the sheet (1C, 66 & 68) is selectively removed to form resistor contacts while exposing a portion of the thick-film component. Electrical terminals (1C, 52A, & 52C) to a thick-film resistor may be sized to reduce stress and/or be selectively positioned relative to the resistor to define a desired resistor value. A thick-film resistor may include one or more resistor segments configured to be selectively open-circuited to incrementally adjust the value of the resistor.
