Challenge
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.
