Solder Mask

How is the solder mask applied? That is, how do they avoid applying the resist to a pad? Similar to etching(using the photomask somehow) or applying a physical mask(like taping over the pads)?

It's silk-screened on using artwork designed by the layout person.

If you would stop trying to use a wrench for a hammer, life would be a lot simpler. Get yourself a proper ECAD and you will find layers called RESIST.

This is free, it's bootable, and it contains 2 ECADs:

Certainly isn't, except for the most basic and low-tech boards. It's a photo process. The whole board is coated, exposed, and developped.

They don't, they avoid it staying there.

Never mind, in less than 24 hours he'll be on a completely different subject, with no clue as to whether or not the previous information was used or not.
