Selective Via Coverage and Exposure on the Solder Mask Layer
Via Solder Mask Expose
Vias Solder Mask Tent
==================================================
PADS VX.2 and later
Certain situations may require that particular vias are covered over by solder mask while other are exposed such as with vias under a BGA. In order to accomplish this you can make a duplicate of your current via and make modifications to the pad stacks that will create solder mask exposure or coverage.
1. Go to Setup - PADS Stacks - Via.
2. Select your existing vias and modify its name to uniquely identify it such as STNDVIA_EXPOSED.
3. Select the Add button under the "Sh: Sz: Layer" column
4. Select the Solder Mask Top layer and click OK.
5. Set the Solder Mask Top pad size to the desired value to expose it in the Solder Mask.
6. Repeat for the Solder Mask bottom layer, if needed.
7. Click the Add Via button.
8. Click Yes to both confirmation prompts that appear.
9. Enter another via name, this time for the covered via, such as STNDVIA_TENTED.
10. Modify the Solder mask layer(s) under the "Sh: Sz: Layer" column to zero.
11. Click OK to the Pad Stacks dialog.
12. If vias are already placed in the design you wish to have covered by Solder Mask set your filter to only select by choosing the Filter from the right mouse pop up and checking the box for Vias.
13. Select the vias on the design to be covered, right mouse click choose Properties.
14. Change the via in the drop-down to your "Tented" via and click OK.
15. Define the Solder Mask Top Gerber document by going to File - CAM - Add.
16. Enter the name for the Solder Mask document.
17. Set the Document Type to Solder Mask and associate it to the Top layer.
18. Click the Layers button.
19. Select the Solder Mask Top layer and enable the Vias checkbox. This box must be enabled so that the Solder Mask layer information overrides the electrical layer pad stacks for the Solder Mask output.
20. Repeat for the Solder Mask Bottom, if needed.
