Just a quick sanity check here - I'm working on a project with an HDI board and I'm heavily pressed for space. I have a lot of external pull-up/pull-down resistors around the board which are currently 0201. I would like to drop them down to 01005 to save space. We don't have an 01005 footprint in our libraries at work, so I created one with the Altium IPC compliant footprint wizard (which uses LibraryExpert as its core). I used the dimensions & tolerances from
Panasonic's 01005 ERJ series as a template, and selected the IPC least material condition (high density).
The resulting footprint seems... wonky:

The inner green box is the component outline, and the outer box is the courtyard. Altium's IPC wizard made the pads 0.15mm wide, which is narrower then the nominal width of 0.2mm for the resistor. I would have thought the pads should be at least as wide as the resistor maximum width (0.2mm + 0.02mm). They also seem overly long at 0.3mm. It feels to me like this part will tombstone.
Can anyone share the dimensions of a good high density 01005 footprint that they've used so I can compare?
