Thick film resistor, method of trimming thick film resistor, and printed circuit board having thick film resistor

摘要

A thick film resistor comprises a substrate made of a material which is uneasily damaged by a laser beam which impinges thereon, a resistor body formed on the substrate in the form of a thick film, and a pair of electrodes formed on the substrate. The electrodes are electrically connected to both ends of the resistor body, and the resistor body has a shape such that the substrate is exposed at least in a portion adjacent to one side edge of the resistor body.
