Polygon: use Rank to draw polygons into each ohter

Thermal Pads: Use thermal symbol connected to GND request level swap use one SMD Pad (TP0) for the surface area use as much Pads (TP1 - TPX) as needed for heat transfer

qfn packages (or othes small pitch packages) : use smd pads with roundness 100% (round edges are better for solder paste release)


Additional Information regarding PCB-Design. This is a work in progress and will hopefully be updated. by: DCEM

Dangerous Stuff

It is possible to edit Eagle Files directly since they are xml files.

Change font on layers 25, 26, 27 and 28 to vector

Regex replace: (<text.*)layer="(2[5-8])">

with: ${1}layer="${2}" font="vector">

Change font size on layers 25, 26, 27 and 28 (0.6096 --> 0.8128)

Regex replace: (<text.*size=")0.6096(" layer=")(2[5-8])

with: ${1}0.8128${2}${3}
