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!
@mfris: HI, I know it is very frustrating to have this problem, the offset can be chose using the offset commands and if you have some issues with the rotating of the components then you should try EDIT->Spin command to rotate the components rather than the other rotate commands and hope it works.
