Does anyone have pointers to footprint guidelines for Power Pad
parts, particularly TSSOP (28 pin in this case).
If I put a pad down the same size as the powerpad and screen
solder onto it, I would expect the part to sit up on the meniscus
when the solder melts and I'd get poor/missed joints

Can you offer a part# as an example link to a data sheet.

I checked the source we use for our footprints and on the TSSOP 28
pin devices with the bottom tab, they suggest a pad the same size as
the tab and their common solder paste deposition of 0.006 - 0.008
Ah ! The penny drops. That corresponds to the distance between
the base of the package
