It’s possible that the solder reduces resistance enough so that the bond wire doesn’t produce enough heat to melt it off, but I guess it’d depend on what kind of solder you use. Also it’d be a pretty finicky job - not impossible though (probably impossible for me though, I’ve only just got started).
I think we could be investigating something else as well. Applying a coating of “something” onto the LED to revert the tint shift from de-doming.

Unfortunately this is Vinz’s trade secret (not vinh from cpf) and won’t tell anyone so this would might prove tricky to figure out.
Ever since he said that it’s been bugging me what Vinz did to produce a whiter beam with ‘no more yellow’.
