Heat spots on Neopixel Mini LEDs

[wonkoderverstaendige]

I have a bunch of NeoPixel Mini 3535s that I am using to solder by hand that have signs of high heat on the solder pads straight from the tape. Is this kind of thing normal?

I have not tested if they work yet, if that's something that can't be trusted I wouldn't even try and use another batch.

Any notes on this would be greatly appreciated!

That's unusual, but not necessarily fatal.

Test a couple in standalone use and see if they work, and how they compare to pixels without those markings.
