Are these components?
msuffidy:
I have a PCIe card that does weird things it seems the more I use it, including disappear from the system.
I was looking at the PCB and I noticed these gold bowties. They look kind of like spark gaps, but they are not gaps, are they fuses or something? Maybe they indicate where the spark gaps are sort of looks like (my camera magnified it so I can see).
helius:
They could function as a PCB fuse; but also they control the thermal conductivity between different areas of copper fill, which can be useful for soldering for example. On old computers like the Apple II, "bowties" were used for circuit options the user could modify with an x-acto knife.
boB:
Could they be modifiable areas where you might want to cut those connections for certain reasons ?
Since it looks like one power plane to another, I'm thinking that is why there are so many.

thm_w:
Its a net tie to connect two nets electrically but allow you to automatically have a clearance gap on the copper pour.
Since they have the exposed copper they could also work as a test point, or as previous say make it easier to cut with a knife.

Infraviolet:
How did those "bowties" remain as exposed copper during manufacture, and not end up with tin/HASL/ENIG/gold or whatever other plating was used covering over them? Most production processes have everything which isn't covered by solder mask plated with one of those covering to make them easier for parts to solder on to.
