This SD card tends to catch in the socket on insertion, which is a nuisance.
Adding one 27 pF 0603 cap lifts it up a bit and fixes the problem. It's on the schematic for the next rev.
It's cool, an unconnected capacitor floating in the middle of the schematic sheet.
Nice way to use a component on the PCB for that function :-)
Sort of like a Sesamoid bone?
Don't the body sizes shrink (from the vendor) with time?

Should've used one of these...
The "available" sizes shrink. The height is part of the part number, so that part will always be the same.
I wanted to use a copper circle, solder pasted, but production says the solder is only 4 mils thick, 5 with the copper. It might dome up a bit in the middle, but the cap is thickness is right and reliable.
I'd use it as a bypass, but all my reasonable bypass values are 0805s.
There are explosives that are, by design, very hard to detonate. Exploding wires and the usual initiators won't work. What does work is something like that, a thinfilm resistor with some kapton-like coating that vaporizes and slaps really hard and fast.
I feel pity for someone who tries figure out why that chip is there.
Competitors. Spies. Good.
Maybe I should connect it to something to make it more confusing.
Patent immediately.

Nice simile.
Danke,
meh... you're using a socket intended for edge-of-board access in the middle of a board, in that location you should use socket with a hinged door.
I did that many years back for Flex-into-Samtec connector. There were actually two to help get the height right for guiding into the connector.
