There are times when you don’t want no soldermask at all.

In that case the first idea would be to leave the Gerber-Layer for Soldermask empty. This, however, is not how it works. Soldermask is a negative mask and thus – though counter-intuitive – you will need to **fill the layer where you don’t want soldermask to be applied**.

Since this is really counter-intuitive, we thought we’d put it into the KB as a reminder in case you need it.
