Product applications for industrial PCBs

Our industrial customers often have thousands of PCBs in service to hundreds of machines. Whether you’re looking to produce one board or a thousand, our facilities in Silicon Valley are the perfect partner for your high-mix, low volume needs.

Sierra Circuits best-in-class PCBs can be found in a variety of industrial applications, including:

  • Power supply units
  • Robotics
  • Electronic switch gears
  • Industrial drives & inverters
  • Electronic test & measurement equipment
  • Energy control systems
  • Industrial smart meters
  • Temperature sensors
  • Radio communication systems
  • Radar systems
  • Electronic smart labels
  • Industrial lighting systems
  • Relays
  • Resistance meters
  • Safety switches
  • Sensors, counters

Reverse engineering

Industrial PCBs might be in service for several years or even decades. Over time, some components may become obsolete or—more often than not—out of production. Whether you need help sourcing reliable alternatives to old components or reverse engineering existing PCBs, the experts at Sierra Circuits can help get your machines back up and running with turn-times as low as 1 day.
