Standard Circuit Trimming System

LT2200 – Thick Film Laser Trim System 

LT2200 is an advanced platform for trim and test of thick film circuits, hybrids and components including PCBs and SMT. 

LT2210 – Thin Film Laser Trim System 

LT2210 is a versatile platform for trim and test of thin film resistors, resistor networks, hybrids, temperature sensitive devices (RTDs) and other thin film – small geometry applications. 


Yield and throughput

  • Absolute coordinates reduce “wandering” of trim positions in step&repeat applications
  • Unification of multiple systems (so-called tool matching)
  • Greater throughput with smaller number of alignments
  • Smaller contact pad geometries possible

Shortened product setup

  • Trim algorithms can be customized by the user
  • Reduced development time for program creation
  • Use of plug-in components for user interface customization
