  • The resistance trimming often use a CO2 laser or Nd:YAG laser as a light source.And the Ar+ laser has shorter wavelength than Nd:YAG and CO2 laser.The reflection index of melt film is smaller for 514.5nm wavelength and it is easy to build a better optical system to provide precise resistance trimming.This paper described the trimming system and summarized much practical data.

Abstract: The resistance trimming often use a CO2 laser or Nd:YAG laser as a light source.And the Ar+ laser has shorter wavelength than Nd:YAG and CO2 laser.The reflection index of melt film is smaller for 514.5nm wavelength and it is easy to build a better optical system to provide precise resistance trimming.This paper described the trimming system and summarized much practical data.
