Method to arrange low-impedance resistor on circuit plate, for use in electric vehicle; involves calculating required resistance per square centimeter to determine required area of thin film microresistor

摘要

The method involves calculating the required resistance per square centimeter, and converting this to a corresponding surface of an all-in resistance. A position with the determined surface is programmed on a circuit plate (1), which is formed with a microresistor (2) formed of long strips of film. A modifiable bridge is placed on a central area of the microresistor, to adjust the resistance, which is installed with a connection at each end of the film, so that the resistor is formed as a continuous flat single-piece of foil. An Independent claim is included for an arrangement for implementing the method.
