QFN-40 footprint with solder mask defined vias

#1 Post by d1wang » 02 Dec 2018, 23:19

Just made this for MSP430FR58xx. Haven't tested with PCB production.

16 solder masked vias according to TI user guide. TI recommends 0.3mm via diameter with 0.4mm solder mask tent diameter. I use 0.5mm solder mask tent diameter just to be safe.

Add a nasty top-left pad that TI says is present in some packages.
