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 In a message dated 9/23/2009 16:23:57 Pacific Daylight Time, [email protected] writes:
If I was to resolder all the joints on something like this, using good old fashioned tin/lead solder, where would that leave me? regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
