I am trying to create a padstack for an LGA package, and the manufacturer suggests an offset solder mask relative to the PCB land - in this particular case they recommend a solder mask opening equal to the PCB land length + .3mm, with the solder mask extending .05mm beyond the land on the inner edge, and .25mm beyond the land on the outer edge.
I don't see an obvious way to do this when I create the padstack (the padstack editor centers the solder mask on the pin), and I'm not aware of any way I can select and move only the solder mask part of the padstack when I'm editing the component footprint. I thought perhaps I could create two padstacks - one with only copper/paste mask, one with only solder mask, but I'm guessing I'll have twice as many pins as I need if I do that. Any thoughts on how to accomplish this the "right" way?
I'm using PCB Editor 16.5.
Thanks in advance for any help!
Thanks for the quick reply - I'm actually a little embarrassed at how simple that was after going back and checking. Not sure how I missed that before. Anyway, thanks again for the help.
Related - since my pin/solder mask was no longer symmetric, I had to rotate half of the pins on my device after updating the padstack. However, some pins would not complete a rotate in place - I had to move the pin, rotate the pin 90, move the pin again and rotate another 90 to get the rotate action to "stick". Anyone else have that experience? I had no issues with the first several pins, and then all of the sudden it was like the rotate feature was broken. I temporarily changed the origin and grid spacing to make it easier to keep the pins lined up, but other than that I was making the same movements to rotate the pins each time. As I said before, I was able to work around the issue, but it was still annoying/frustrating.
