Add TI S-PVQFN-N40 (RHA) to Package_DFN_QFN.pretty

KiCad Bot requested to merge github/fork/aimylios/s-pvqfn-n40 into master

Created by: aimylios

This PR adds the footprint for S-PVQFN-N40 (package code RHA) from Texas Instruments. It is required by some of the MSP430 devices I am currently working on. I based it on the information from the MSP430G2x55 data sheet (pp. 70-72) with only two exceptions:

  • pads are elongated by 0,14 mm to accommodate for the rounded shape on the outside (which is not part of TI's recommendation, but semi-rounded pads are not supported in KiCad yet)
  • a keep-out zone at the pin 1 marker is not included (TI says it's optional, and KiCad doesn't have native support for keep-out zones anyways)

There is already a similar footprint Texas_PVQFN-N40 that should also be named Texas_S-PVQFN-N40 (to avoid confusion with the R-PVQFN variants). It is based on the DRV8308 data sheet (pp. 56-58) and is not compatible to the one I made. Are there any guidelines how the naming should reflect these differences?

I think it might be a good idea to script all of the S-PVQFN-x footprints in the future to get a more uniform appearance.
