Is it time to replace your older resistor trimming system?

RapiTrim laser resistor trimming systems combine modern hardware and software with worldwide support to provide a complete solution for circuit and component, chip resistor and semiconductor wafer trimming.

Upgrading from an end of life or obsolete resistor trimming system.

As resistor trimming systems designed in the 1980’s and 1990’s reach their end of life, manufacturers are increasingly forced to choose between continuing to perform repairs and commit to increasing time spent performing maintenance, versus purchasing new equipment.  Avoiding unplanned downtime and the high cost of repairing obsolete manufacturing equipment must be balanced against the cost of new capital equipment. 


Modern resistor trimming systems, with continuous development, integrate present-day electrical, mechanical and software features that are required by manufacturers. Equipment must be able to meet the speed and accuracy requirements of today’s production line as well as future manufacturing needs.

PPI Systems works with customers at every stage of the purchase to assist in making the decision to upgrade, designing systems to fit into their production line, providing a complete installation, training and support plan.

Easy Integration

We’ll work with you every step of the way, from initial application decisions, sample processing and job creation to customization and successful installation of the system. And then we’ll be there to provide advice and support going forward. Our main 3500 sq. ft (325 m2 ) application lab offers a complete array of services for both laser drilling and resistor trimming customers.


In addition, we extend our system offering with forward looking products, applications and concepts based on industry trends and customer specifications.

With over 20 year’s experience designing and manufacturing laser processing systems, PPI has the knowledge needed to ensure a problem-free installation.

Higher yields, quality and volumes.

Next generation resistor trimming systems take advantage of the most modern hardware options available. Critical components such as lasers, cameras, stages and galvo controls use of the latest technical advancements, which translate into faster, more adaptable laser resistor trimming systems which meet today’s specifications and applications. 

Common features include: 

  • Automatic planarization (roll/pitch) and Z calibration
  • High accuracy, high bandwidth real-time measurement system
  • Automatic job setup
  • Full automation including stack and magazine loaders, in-line and custom options
  • Wireless probe cards
  • Profiled motion trajectory control which improves probe tip placement and contact precision

RapiTrim systems also include automated DXF import to speed job creation, a modern user interface, and other advanced features like unique beam position calibration.

Lowered Cost of Upkeep and Repair

There is a broad range of concerns that you cannot avoid when your equipment begins to approach the end of its lifespan. Older machinery tends to require more maintenance than newer systems.

Aging equipment is likely to break more often, and allowances have to be made for routine repairs and stoppages for calibration.  In addition, manufacturers may cease support for older systems making access to service and documentation a difficult task for operators and maintenance teams, especially in cases where the OEM no longer is in business.  PPI Systems provides the highest levels of support for all of its newer laser resistor trimming and via drilling systems. Customer support, training and information resources are available to optimize operations and trouble shoot any issues that arise. Advantages include:

  • Stocks of replacement parts eliminating concerns of finding defunct or aftermarket parts.
  • Reduced downtime with and associated loss of production.
  • Performance and equipment effectiveness is improved.
  • Reduce energy costs.
  • Improve the quality of your output, reducing waste.

It is also important to consider upgrading as an investment with the benefits that new equipment can bring, such as improved quality, speed and customer satisfaction. By being proactive and recognizing that it is time to upgrade, you can make informed decisions that will benefit your business in the long term.

Modern Laser Trimming Optional Features

Options include stack loaders, automated probe-tip change, custom fixturing, switching matrix, external instrument support, bar-code readers and process sequence customization. These up to date add-on features ensure systems work at the highest speeds possible, something that is critical for high volume production facilities.

PPI’s ability to offer many customization options from a single vendor allows us to create solutions for any application, whether high mix, low volume or high-volume production manufacturing. With dedicated models for circuit and components, chip resistors and semiconductor wafer trimming, our application engineers are able to offer unbiased design support as PPI Systems designs systems to match any application.
