Test System Development Process

Test Systems are designed to execute automated Functional Test Plans, and are most often implemented in production-level fixtures (development-level fixtures also occasionally fall into this category). Simple Test Fixture Designs (mechanical-only fixtures) do not require this level of design effort. FixturFab has developed a standard, comprehensive process for designing Test Systems that will be explored in this series of articles.

Manufacturing Phase

Manufacturing Phase

Upon completing design reviews of the electrical and mechanical components, FixturFab proceeds to fabricate and assemble all components. Rigorous quality checks will be conducted throughout the process to ensure that every part meets the highest standards of performance and reliability.

FixturFab’s shop is populated with a variety of machining tools that we use to custom manufacture your Test System

  • CNC machines for fixture plate milling & drilling (e.g. FR4 probe plates)
  • Laser cutters for acrylic cutting (e.g. back plates, pressure plates, etc.)
  • 3D plastic printers for a large variety of custom parts

First, FixturFab needs to fabricate the custom parts designed for each Test Fixture. A combination of techniques are used.
