Multiple High Voltage Pulse Trimming Method (MHVPTM) of Polymer Thick Film Resistors
Busi Rambabu and Y. Srinivasa Rao

In order to realize a non cut trimming without damage to the surface of thick film resistors for electronic devices, a Multiple High Voltage Pulse trimming method (MHVPTM) has been developed. This trimming method having resistance adjustments are due to peak amplitude of high voltages and the number of impulse group. TCR and current noise of trimmed are considerably improved by this trimming technique in the case of higher resistivity materials and worsen in the case of lower resistivity materials and there is no loss in power handling capacity of trimmed resistors.
