Vertical Probing

Vertical Probing


As more advanced functions integrated into small form factor circuit boards, most of them have components populated on both sides of the PCB. Measuring a signal or impedance trace routed from one side to the other side of the PCB requires holding the board vertically and probing them from both sides.

VPS100 Probe  Station

  • Solid vertical PCB holder grips the PCB firmly and stably.
  • Magnetic bases allow a user to easily move the PCB for the ease of probing.
  • Flex Positioner FP160 makes good probe placement and leveling easy and quick.
  • FP160 can also hold microscope to view probe tips and DUT in almost any orientation.

Things to Consider for Vertical Probing

  • Find a sturdy vertical PCB holder griping the PCB firmly to withstand the probe forces from both sides
  • Find a probe holder capable of holding the probe in various orientation with fine position adjustment
  • Find a microscope that can view hard-to-reach area
  • Adjust the PCB to the correct height
  • Make sure the probes cannot be blocked by cables or connectors
  • Use the microscope to level the probe to ensure all the probe tips can touch the PCB evenly.
