Samsung HinFlux led strip.

Not sure if that's a dig at me ;) but those strips look like they have plenty of matrix clearance around the mounting holes, which are also ally. I've used metal washers with all my strip builds, as they clearly fit inside the matrix with no risk of shorting out. Most of my strip frames have been running close to a year now without issues.

Sarcasm aside, is there any real reason to use nylon washers? I would definitely consider using these for my next builds.

No, I'm not that type. If I have something to say I just say it, direct. As i did...

I'm not even sure what they are.

I thought that myself but the tc points in the center. I cant see anything on the data sheet.
Yeah, I see now that they are different. My Acuity strips have these, as do my F series. Can't imagine what those spots are for.

Looking close I see they are just untinned copper plate circles, not connected to anything and not going through to the other side. Perhaps they are optical registration points for the solder mask.

Are they not the test points to test the boards? I know some of the boards and strips have those spots to apply current to test the boards.
My f-series strips have them, the QB 288 boards have them.
When applying a multimeter to them, you can read the voltage
The + right next to it is what makes me think this, is there one with a - next to it somewhere else on the strip?

The ones that are just a circle with the plus and minus symbols are test points - but the ones with a square outline around them are not connected to anything. I just verified that with my meter on my single row 22 inchers. Having worked in circuit board manufacturing, the most likely function I can think of that these would serve is for optical registration when applying the solder mask.

Isnt it just a circle with no square outline? Although it doesnt even look like the other test points that I've seen, only one way to find out for sure though.
Just weird it would have a + reference right next to it

Never mind, I think we were looking at different spots.
I was looking at a different image and didnt see the one with the square.
