Hi Nigel,
since you are only concerned about a couple of sample units, I would not be
too worried about the tin-whisker problem. Probability of failure is still
quite low for a single unit, even if massively higher than with lead
solder. If you ordered 10,000 units that would be another issue :)
Even if the part stops to work, you can probably take a toothbrush etc and
you might be able to brush off all the whiskers (unless the short was
catastrophic).
I tried re-working RoHs boards with lead solder, and this does not result
in shiny solder joints either. It doesn't even seem to change the eutectic
temperature of the joint much.
Would be very interested in any actual test results you get with your
boards though.
bye,
Said

If I was to resolder all the joints on something like this, using good
old
fashioned tin/lead solder, where would that leave me?
