I use teensy 4.1s in a prodct of mine and need to cut the VUSB to 5V jumper.
This has worked fine for a couple of boards so far but the last one I just cut I fear may have damaged something.
How deep can one cut into the surface before the likelyhood of damage?
It is.1.6mm I would guess unless it is a multilayer PCB.
Every board with high pin-count BGA parts is at least 4 layer, though usually 6 or 8 or more - its the only way to route all those pins from the middle out!1.6mm I would guess unless it is a multilayer PCB.
