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 |

The Silkscreen Legend and Polarity Marking to Solder Mask gap minimum is 3 mils or 0.075 mm. |
