SOT-143 footprint
Created by: matianfu
I have check several documents for this package, including:
- onsemi: https://www.onsemi.com/pub/Collateral/318A.PDF
- diodes: https://www.diodes.com/assets/Package-Files/SOT143.pdf
- nxp/nexperia: https://assets.nexperia.com/documents/package-information/SOT143B.pdf
Apparently, the sot-143 footprint in current KiCAD library is way too large. It is for wave soldering, not for reflow. Furthermore, Pad for pin 1 is misplaced. The edge is not well aligned. There is no reason to do so.
