RapiTrim Laser Resistor Trimming Systems

PPI Systems designs and manufactures the most advanced turnkey laser resistor trimming solution for modern hybrid circuits and electronic components in the world. We have over 18 years experience creating resistor trimming systems which have been adopted by the largest thick and thin film manufacturers globally. Features include:

  • Flying probe, probe card and custom measurement 
  • Passive or active trimming options with custom fixtures
  • Designed with modern software and hardware with higher speeds and increased reliability
  • Optional sample handling, magazine loaders, external instrument support and process sequence customization
  • Global customer and technical support

Able to handle both high-mix, low volume and high volume applications with ease, RapiTrim systems are easy to install with intuitive software and over 100 years of combined application experience shared by our engineering and R&D groups. No matter what your job specification, there is a RapiTrim laser resistor system to meet your needs.

RapiTrim-C Flying Probe Laser Resistor Trimming Systems

Standard models incorporating PPI’s proprietary high-speed flying probe technology eliminate traditional probe cards, providing many advantages:

  • Circuits can be as large as the substrate itself
  • Probing of dense designs is effortless – previously required multiple passes with multiple probe cards
  • Four independent flying probes – any component location, size, orientation and layout can be accommodated
  • Net throughput higher than probe card solutions that require lengthy programming and multiple passes

RapiTrim-P Probe Card Laser Resistor Trimming Systems

When your high volume production needs are best served by a probe card system, RapiTrim is the system of choice due to the automated DXF import to speed job creation, the modern user interface, and other advanced features like the unique beam position calibration.  

  • Designed for high-volume production
  • Compatible with industry standard probe cards
  • High performance 4-axis prober with precision step-and-repeat substrate handler
  • Profiled motion trajectory control improves probe tip placement and contact precision

RapiTrim-A Active Laser Resistor Trimming Systems

Available for all three laser systems (IR, Green and UV), allowing the adjustment of the whole circuit output such as voltage, switching threshold or frequency.

  • Test connections can be made through a combination of application-specific top-side probing, bottom-side probing, flying probe or custom fixtures
  • Full support for software control an connection of external instruments with integrated active trim sequence scripting

Fixtures are designed at PPI Systems and are simple to install and remove, ensuring the fastest possible active trim cycle time.
