Challenge
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
- Bench top design can fit any bench table
- PCB size can be as large as the bench table
- Magnetic stackable bricks allow different height adjustment
- Positioner can sit on top of stackable bridge or stackable bricks
- Boomstand microscope is suitable to probe any corner of a large PCB
- 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
