Hi, the following are some thoughts that may explain
and perhaps help.
Looks like what is being referred to is "water soluble
flux." It's primary use is in the mass production of
PC boards on commercial wave soldering machines.
Discrete components are first either manually
place/inserted or pic

As a matter of interest, what are the possible advantages of such a

recommended to me to use Acetone to clean off solder resin. You might try
that to see if it cuts the apparent tarnish.
Sounds like you might have to redo every solder joint on the RF board after
removing as much
First of all, you are correct, it is corrosion. I have used plenty of
Kester Organic Core Solder, Flux 331. I still use it a lot.
The rules I follow are:
1) note the time the first solder joint is made.
2) not more than 1 hour later I take the work in progress to the sink

Folks;
It would seem to me to not be from rosin or resin core solder; if it is
corrosion, it sounds more like acid core solder; perhaps it was mislabeled.
The term organic unfortunately is frequently misused; all hydrocarbons
are organic right? Water soluble? I assume the flux, as in wash a

I would think you could use a good solder sucker and suck all the bad
solder off the board.
Then re-do all joints with the correct solder.
Are you sure it's really corrosion?

Wow Joe!!!
Rosin is extracted from tree sap - Pine trees mostly. It's "organic" and
water soluble by definition. The "water soluble" doesn't refer to the
solder, only the rosin.
Something else happened to your K2 besides using an "organic" core solder.
Maybe accidentally using an acid flux ins
Just a friendly warning to those who may not know the exact origin of their
solder. I used a Kester solder that was labeled "organic rosin core" on my
K2 (only 75% of the RF board) while I was waiting for a re-supply order to
come in.
Fast forward one week:
