ABSTRACT

 

In order to realize a non cut trimming method without damage to the surface of thick film resistors for electronic devices, a Universal Trimming Method (UTM) has been developed. This trimming method having resistance adjustments are due to peak amplitude of high voltages and the number of pulse group. TCR and current noise of trimmed are considerably improved by this trimming technique and there is no loss in power handling capacity of trimmed resistors
