Abstract

Hybrid circuits, such as used in channel element designs, make use of top hat resistors to compen- sate for circuit tolerances. Sometimes, during circuit compensation, which is done by using a laser to trim the resistors, the required resistor value is overshot. in other words, the laser overtrims the resistor to a higher than desired value. in this case, the hybrid is no longer usable and it must be scrapped.
