the difficulty I've had clearing those bridges.
I can't understand why solder braid doesn't just lift it off. I wonder if you are not using fresh high quality braid?
I might have bought it at Radio Shack 15 years ago or something like that.
Does rosin core solder dry out as well?
In the meantime would saturating the wick with flux work okay?
, making it the only suitable thing for very fine pitch soldering.
The traces are not even close to being impossible to solder. That's not the problem. It's the ease with which the connector pins bridge and the difficulty I've had clearing those bridges.I have another adapter board from the same Chinese source, same type of traces, 0.8mm pitch. Soldering a TQFP-32 part to the board was very, very easy.
What happens is that the flux impregnated in the braid drys out making it not suck up the solder. It sounds like you should try some fresh stuff.Some one told me that anything over 6 months was old but I have used braid that is three years old without problem.
