I gave it a shot with your advice just earlier with multiple LEDs, but nothing changed. I swear, it's like there's some magic bullshit barrier preventing the pads from being adhered to. It isn't like these were dirty loose ones either; they came in a roll with plastic sheet lining covering them from debris and damage. Whether trying to bridge or do them in isolation, nothing changes. I have no idea how I made it work in the past, but I never had any issues with these like this before. The absolute best I could do before is pic related with a sacrificial LED for testing (like rolling over with a blob of solder).

Already tried it. The problem is it won't adhere to the metal AT ALL, or if I'm lucky, juuuust barely. It's so inconsistent and impenetrable, it's baffling.
