Flying Probe Technology that Replaces Conventional Test Fixtures

Huntron Access Probers

Precision Flying Probe Platforms for Automated Test Applications

Flying Probe technology is used to automate the testing of printed circuit boards (PCB) that would otherwise have to be tested manually. Adding a Huntron Access Prober to your test procedure will significantly decrease test times therefore increasing productivity. Access Probers can accurately place a probe on test points with high accuracy achieved using micro-stepping motors and linear laser encoders. Probing the smallest surface mounted devices is possible.
Huntron Access Probers can automate your unique test process using the standard probe or by adding a custom probe of your design.
Huntron offers three Flying Probe system configurations based on PCB size and test head requirements.

Huntron Robotic Flying Probe Systems FAQ

  • Q: Where are Huntron Robotic Flying Probe Systems used?
    Answer: Huntron Robotic Flying Probe Systems, known as Huntron Access Probers, are used in any situation where you wish to automate a test function that is currently done by hand. Automation greatly reduces the time required to interface to test points on a printed circuit board or perform a function that was previously accomplished manually. Flying probe systems can also reduce errors caused by fatigue or placement accuracy that are possible when probing manually.
  • Q: What can I test with a Huntron Flying Prober?
    Answer: Many flying probe systems including the Huntron Access Probers are used to test electronic printed circuit boards (PCB). They provide a reliable, fast and repeatable method to test PCBs that are either powered ON for functional type tests or powered OFF for static diagnostic testing such as Analog Signature Analysis (ASA). Because of their unique XY platform design, Huntron Access Probers have also been used for other applications such as custom pick and place and automated optical inspection (AOI).
  • Q: How are Huntron Prober systems different to other Flying Probers such as Takaya, SPEA, Acculogic and Seica systems?
    Answer: Where many flying probe systems like those from Takaya, SPEA, Acculogic, Seica, Condor or Seika are high speed production test systems, Huntron Access Probers are intended for low volume, high precision test processes. These processes may include Analog Signature Analysis, automated digital multimeter (DMM) probe placement, inject and sense measurements, and precision, low volume pick and place functions. Huntron Access Probers provide a flexible robotic XY platform that can help automate functions where manual methods are not practical.
