@rahix not sure if this microscope is suitable for PCB rework. You do not have much room underneath the optics.
In addition to the Sensepeek PCBite holders I lend to FAFO, I bought the following:
- 1x Sensepeek 4014 SP200 Tastkopf (200 MHz)
- 4x Sensepeek 4005 SP10 Tastkopf-Set,
- Sensepeek 4017 PCBite…
