Laser Systems for Circuit Trim


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 control and throughput

  • Absolute coordinates - minimizes beam “walking”
  • Superior matching between multiple systems
  • More throughput with fewer alignments
  • Enables smaller pad sizes

Reduced setup time

  • End user customization of trim algorithm
  • Minimized program development time
  • Insertion of user interface controls via plug in components
