Resistor Active Laser Trimming
Laser trimming plays an important and essential role in Thick-film resistor networks, is fast and inexpensive. This manufacturing process can adjust the resistance of thick film printed resistor for custom design.
Laser standard
- MIL-STD863G (United States Military Standard)
- Laser trimming precision:±0.1% Resistance
Laser Trimming Specification
Most cost effective and simplistic
Minimum Precision
Trimming efficiency is lower than plunge cut
Precision is higher than plunge cut
L cut is used most often
Has good stability and accuracy
Serpent line cut usually used in trimming if pre-trimming resistance value is much lower than the targeted value
Used for high accuracy trimming
Low trimming efficiency but high stability
