This is known as gold embrittlement.
The gold has to be removed before a good solder connection is made.
To remove the gold, tin the gold plated area.
Desolder the tinning.
Retin and remove the solder three times.

Only the turned edge connector pins of the two PCB's inside the oven
appear to have that problem.
I looked under a good microscope, and the female contacts as well as the
trimmer cap, both gold plated, looked good.
Now 12 hours later, the 4060 is still running fine with no alarm light

Adrian,
you did actually broke it down to the inside oven level. Is there any thing
to look out for. I have a FTS 1200 that has a problem 2 Hz off but I have
been reluctant to open it up. Any advice?
Thanks Bert

Re-seat all of the boards several times. Just to eliminate oxidation as a
possible cause.

Gold doesn't always solder that well either. Yes, it doesn't oxidize, but
often in a production environment, we dip the leads and pre-tin them just to
make sure they take in the wave.

Hi All:
I'm new to the list. I posted almost 2 weeks ago but never got a reply, so
thought I'd try again. I recently picked up a Datachron 3650-133 GPS
Synchronized Time Code Generator to use as a timebase for my amateur
astronomy observatory. I've looked all over for a PDF of the manual
IMHO gold does not tarnish but below/above the amalgam of gold with solder the
solder probably will. The best solder connect will be where the different metal
layers amalgam deeply. A thicker gold plating should work better.

Hi
Some places use up PC boards a lot faster than others. Board oxidation can
be a problem if you have a board in stock for a couple of years before it's
used. In some cases having a tomato soup plant or sulfur hot spring, up wind
can compound the issue.

Can you add a cup-holder, those are essential these days.
