Hello Nick,

Thanks a lot for the "Polarity Marking Silkscreen Legend" documentation!
I noticed that you write below the 3 Gull Wing Terminal picture, that the gap marking symbol/solder mask should be 0.75mm and on the next page, regarding the sample 0.50mm pitch SOP, the gap legend/solder mask should be 0.075mm...?...
Is that OK or did I misunderstood something?

Thanks and kind regards,
Patrick
