Laser trimming of electrical components

摘要

A method of laser trimming an electronic component to achieve a desired electronic characteristic including entering into a controller the desired value of the characteristic of the component being trimmed, measuring the beginning value of the characteristic of the component being trimmed, determining the value of the length of a first leg of cut of the component by reference to information based upon cuts of legs of different lengths of a component of the same geometry as the component being trimmed, and cutting the component being trimmed using the laser to obtain the first leg of the cut.
