Here is an interesting situation:
One of our hand soldering station came back from yearly calibration test and a significant degradation in accuracy.
We are using it in 300 and 350 Celsius. The calibration test results indicate the the nominal value is approximately 50 Celsius less than anticipated; declared accuracy should be about 10 Celsius.
Obviously, the tool will be put out of service, but we need to make an assessment of impact on products that were released to the field.
Obviously, we don't have tractability at that level.
And so my question: how do I justify that the soldered quality is acceptable?
I am thinking to write that the soldering temperature is higher than the melting point of the solder. Is there something better to write? I believe I'm on a grey area... I guess the good news is that the soldering station did not produce 50 Celsius more than anticipated.
Thanks in advance.
