Dar Chris Smith,

Part of our Preventative Maintenance Service is statistical analysis of
solder sampling over time. If properly logged and analyzed (mathematicaly)
one can determine "out of limit" trending BEFORE one exceeds limits.

A complete "pot dump" is not always necessary, either. For example, tin
levels tend to creep downward over time, and not only can one predict the
out of limit timeframe, but corrective action ic to add a very specific
amount of tin to the pot.

Please feel free to contact me offline if you would like to discuss this
further.

Regards,
