Thick Film Laser Resistor Trimming
Passive and Active Laser Trimming of:
- Standard Thick Film resistors
- Resistors printed on Dielectric over embedded conductors.
- Resistors on LTCC, Al203, AlN, PCB substrate material
Functional / Active laser trim & test: We will work with your engineering staff to develop custom applications software, support circuitry / hardware and an optimized process for Functional / Active Laser Trimming & Test.
Ratio-Match and absolute Post-trim tolerances of: +/-0.01% possible, resistor material and design dependent.
Highest verified trim nominal value: = 500 Mega-ohm +/-5%, higher with custom fixturing.
Lowest verified trim nominal value: = 5 milli-ohm +/-5%
Active guarding for closed-loop resistor trimming
Custom applications software written in-house
Permanent probe cards assembled in-house
Thickfilm spotsize: = 20 to 50 um
