Method for producing a plurality of resistance modular units over a ceramic substrate

A method of manufacturing a plurality of resistor units that each comprise a carrier having a group of resistor elements each including ends provided with a respective first and second electrical terminal, the method comprising:

• a) providing a carrier plate that has an upper side and a lower side;
• b) forming a plurality of strips of a resistor material at the lower side of the carrier plate, that have a first end and a second end along a transverse direction, in a regular pattern such that a respective row of strips of the resistor material is formed along a longitudinal direction that extends perpendicular to the transverse direction and such that a plurality of such rows are arranged next to one another in the transverse direction;
• c) forming a plurality of zones of an electrically conductive material at the lower side of the carrier plate, that have a first end, an intermediate region, and a second end along the transverse direction, in a regular pattern such that a respective row of zones of the electrically conductive material is formed along the longitudinal direction and such that a plurality of such rows are arranged next to one another in the transverse direction, wherein the rows of strips of the resistor material and the rows of zones of the electrically conductive material are arranged alternately in the transverse direction, and wherein, with the exception of border regions of the carrier plate, the strips of the resistor material overlap the first end of a respective zone of the electrically conductive material at their first ends and overlap the second end of a respective zone of the electrically conductive material at their second ends;
• and
• d) cutting through the carrier plate by regular transverse incisions along the transverse direction, first longitudinal incisions along the longitudinal direction, and second longitudinal incisions along the longitudinal direction such that the transverse incisions extend between groups of strips of the resistor material that are associated with one another and that are adjacent to one another in the longitudinal direction, such that furthermore the first longitudinal incisions detach the first ends from the intermediate regions of a respective row of zones of the electrically conductive material, and such that the second longitudinal incisions detach the second ends from the intermediate regions of a respective row of zones of the electrically conductive material such that a respective resistor unit and a respective residual section of the carrier plate are alternately formed along the transverse direction, said residual section including detached intermediate regions of a row of zones of the electrically conductive material.
