Large PCB Probing

Large PCB Probing


It is difficult to cover all the test points with various orientations on a large PCB because of its size. For example, an engineer might need to rotate the PCB by 45 degrees to reach certain test pads in diagonal orientation.

Stackable Probing Solution

  1. Bench top design can fit any bench table
  2. PCB size can be as large as the bench table
  3. Magnetic stackable bricks allow different height adjustment
  4. Positioner can sit on top of stackable bridge or stackable bricks
  5. Boomstand microscope is suitable to probe any corner of a large PCB
  6. Stackable bricks can sit on tester, backplane environment or inside chassis for easy probing

Things to Consider for Large PCB Probing

  • Adjust the PCB in the correct height
  • Verify the test probes and microscopes can reach any corners of the large PCB
  • Find out whether there are diagonal pads needed to be probed.
  • Make sure that test probes are not blocked by cables or connectors
  • Use probe with long tips whenever possible, so that the components won't stop the probe adjustment
