Active-Trim Laser Resistor Trimming System

Laser Resistor Trimming System

RapiTrim-C with additional capability for active trimming of circuit performance (e.g. voltage, switching threshold, frequency ...).


All three laser systems (IR 1064 nm, green 532 nm and UV 355 nm) can be customized to active-trim systems with user-specific fixturing, to measure circuit output characteristics rather than the individual resistor values measured in passive trim systems.  Systems allow either a step-by-step trim or a continuous trim, with continuous trims allowing a feedback signal that can directly control the laser trimmer creating a continuous loop until the specified values are reached.


Advanced laser and beam control, combined with available proprietary high-speed flying probe technology allows the RapiTrim systems to outperform older technology in both high volume production as well as low-volume, high-mix operations.  Circuits can be as large as the substrate itself, and probing of dense designs is effortless, previously requiring multiple passes with multiple probe cards.


System Features Include:

  • Intuitive Graphical User Interface with ProSys operating software
  • Advanced Beam Positioning and Laser Pulse Control provide high throughput, accuracy, and process stability
  • High Accuracy, High Bandwidth Real-Time Measurement system
  • Auto-Calibration functions ensure repeatable quality
  • Extensive System Diagnostics continuously monitor all critical components and machine performance
  • Sealed Beam Delivery protects optics from process debris, extending component lifetimes
  • Touchscreen operation (full HD size)
