Introduced: January 1995

Title

Titles differ between systems:

IPC: by opening or closing resistor tracks of predetermined resistive values

CPC: by opening or closing resistor geometric tracks of predetermined resistive values,

Full Title

Full titles differ between systems:

IPC:

Apparatus or processes specially adapted for manufacturing resistors > adapted for trimming > by opening or closing resistor tracks of predetermined resistive values

CPC:

Apparatus or processes specially adapted for manufacturing resistors (providing fillings for housings or enclosures H01C1/02; reducing insulation surrounding a resistor to powder H01C1/03; manufacture of thermally variable resistors H01C7/02, H01C7/04) > adapted for trimming > by opening or closing resistor geometric tracks of predetermined resistive values,
