My first time using a DFN; I notice that all of the DFN footprints in the KiCad libraries have a long silkscreen line at the bottom of the part (farthest from pin 1), whereas pretty much every other IC package family (SO, QFP, TSOT, etc) uses a long silkscreen line to denote the pin 1 side.
When I saw the first one, I said “Oh, this is an error in this library part”, but then I saw that all of the DFNs are like this. So I said “OK, I guess this is the standard for DFN”, and “the assembler will get the correct orientation from the fab layer and the POS file”.
Well, guess what, the boards came in today and they assembled them with pin 1 toward the big line
What should I have done differently? And why doesn’t the DFN silkscreen in KiCad libraries follow the same convention as every other package family???
