Paper Abstract

The adjustment of film resistors to specified value by selective removal of film material with a programmed laser beam has been practiced since 1966. Evolution of systems to perform not only passive resistor trim but adjustment of operating circuit parameters has led to sophisticated multipurpose machines. This paper describes such a trimmer and correlates the utilization of its various configurations with trim requirements of several types of product. Precautions and suggestions on adjustment of system parameters are discussed to optimize results with respect to accuracy and stability of trimmed resistors.
