I occasionally see this residue where the components are soldered. Is this
flux? Something else?

I'm not sure what that is, but it doesn't look like any flux residue that
I've ever seen. The little brownish 'blobs' on the tops of Q200's legs do,
as does the lttle patch at the upper edge of its centre leg. If it is flux
residue, I'm sure that you would agree, as a repairer yourself, that it is
very unusual for it to be white like that, which is why you are asking for
the opinions of others on here, I would guess ? Perhaps solder guru Smitty
could offer an opinion from the production point of view.
