It frequently does that, so you are not wrong, but it is not a reliable insulator. If you need insulation or spacing for engineering or compliance reasons, you cannot rely on solder mask to provide it.
- elihu 2y agoI mean the kind of shorts where you accidentally drop a screw on the PCB, drag a loose wire across it, or something like that. Not foolproof, but it probably reduces the risk of damage somewhat.
- buescher 2y agoRight, and I think your language was careful to imply that, but others reading this should understand solder mask does that but it's not what it's for, if that makes sense. The bit of mechanical and environmental protection it can provide after assembly is similarly incidental.
