Paste & mask layer, and gold finger leading edge, also gold finger lengths #1
Description
The gold fingers has paste layers on.
In actual designs (e.g. my SSD M.2 2242 at hand), they seem to add a strip of mask layer, not just on the gold finger, that is, no solder oil between two adjacent gold fingers.
Also there's a 0.30 mm gold finger leading edge to avoid gold finger being damaged during the 20 deg chamferring.
Gold finger length on top side is 2 mm and bottom side is 2.5mm, but in templates they are all 2.5 mm (though i think it won't make it unusable)
