What is this Soft SMD Standoff?

[Bruce Chou]

I'm looking for a soft standoff that can be reflow soldered on the PCB, like the one in the picture below. Unfortunately there are no markings and I have no idea what this part is. Has anyone seen this before and knows a place that makes this part?

I have never seen such a component. I think it is likely not a single component as a soft material is likely to melt during the reflow process. From the side view I guess this is a smd component soldered onto the PCb plus a soft standoff (or whatever that blob is good for) glued on top after soldering.

Is it a component? A 45 degree view might help. It could just be a pressure pad to relieve flexing on the board? I can't see any solder pads or tracks to it.

I can't see any solder pads or tracks to it.

No tracks, but in the right photo there seem to be copper pads (gold plated?) in the lower left corner and upper edge.

Why? I doubt there is anything about the device that needs such an arrangement. The felt or whatever it is, would still need an adhesive to attach to a metal back plate, and the adhesive could directly attach it to a PCB instead.

It seems more like a hack to fix a manufacturing/design mistake, that they didn't design adequate mounting or their measurements were off so the board flopped around too much and they didn't want to scrap them and start over.
