Abstract
A resistor trimming method which brings about a good surge resistance and which allows a quick and reliable trimming, including the steps of forming a first slit 141 from an edge A of a resistor 11 formed between a pair of electrodes 12a and 12b provided on an insulating substrate 13, the first slit being in the proximity of and in parallel to one electrode 12a, forming a second slit 142 as a continuation of the first slit 141 toward the other one of the electrodes 12b, the second slit 142 being perpendicular to the first slit 141, and forming at least one approximately L-shaped slit 143 as a continuation of either one of the first slit 141 or the second slit 142.
Claims4
A resistor trimming method, comprising steps of:
- forming a first slit from an edge of a resistor formed between a pair of electrodes provided on an insulating substrate, said first slit being in the proximity of and parallel to a first one of said electrodes;
- forming a second slit as a continuation of said first slit toward a second one of said electrodes and perpendicular to said first slit;
- forming a third slit from an edge of said resistor in the proximity of and in parallel to the second of said electrodes;
- forming a fourth slit continuously from said third slit toward the first one of said electrodes and perpendicular to said third slit;
- forming at least one approximately L-shaped additional slit as a continuation of said first slit;
- and
- forming at least one approximately L-shaped further slit as a continuation of said third slit, said at least one additional slit and said at least one further slit alternate with one another.
A resistor made from a resistance material by a printing method and formed between a pair of electrodes, wherein a first L-shaped slit having first and second ends is provided in the resistor between the pair of electrodes, the first end of the first L-shaped slit begins at an edge of the resistor between the pair of electrodes, the L-shaped slit running substantially parallel to the electrodes from the first end and substantially perpendicular to the electrodes from the second end, and the first end is located within about 0.3 mm from a first one of the pair of electrodes, the second end is located within about 0.3 mm from a second one of the pair of electrodes.
