Solder Mask and Cream in Eagle - Electrical Engineering Stack. Segnala un'altra immagineSegnala l'immagine offensiva. Many beginners may be confused about Solder Mask Layer and Paste Mask Layer, because they two do have some similarities.


When I paste Cmd + V a new layer is created instead of pasting into.

Alt + click on the layermask icon in the layers palette, you can then edit it. Solder mask defined pads under fine pitch BGA packages. Multiple separated squares on the paste mask layer to create area reduction .
