NADCAP and thermocouple calibration

And to my knowledge, there is no calibration of Thermocouples. They can only be checked for their continuity and resistive value. The question would appear to be invalid.

NADCAP and thermocouple calibration

Hege, there is no actual calibration of the thermocouple itself. You can however verify that they read correctly. Heller sells an option on their reflow ovens specifically for this purpose. I hoping that someone chimes in here that is NADCAP certifi

I was asked how we verify that the thermocouples INSIDE the reflow oven are calibrated. That seems pretty impractical to me. Has anyone come across this ?

You mean you don't pull all of your thermocouples out of the ovens once a year and send them out for calibration? - lol Tough question. You have a calibrated datalogger. (I assume) You have an oven with preset zone temps, each zone controlled by a

I too am hoping a NADCAP guy might jump in here. I would like to know how this portion of the question is handled. Evidence of PM, periodic cleaning of EQ and tools, no issues. Thermocouple calibration? You would think that evidence of Oven CAL

Is it the correct type of thermocouple? If it is designed for a K type and you put a J or T the reading will be lower. Also a bad connection can give a lower reading.

Who can tell me the IPC** about the thermocouple for reflow and rework? I'm waiting....

No such thing. Check with your temperature measuring equipment supplier.

Type K thermocouple for Super M.O.L.E

Electronics Forum | Mon Nov 05 20:31:09 EST 2001 | davef

Most people do not intend to �solder� Type K thermocouples. They use solder to �attach� the thermocouple. Search the fine SMTnet Archives for a posting by Chrys Shea. 1 Common thermocouple types commonly used for thermal profiling are: * Type K �

Type K thermocouple for Super M.O.L.E

Electronics Forum | Sat Nov 03 05:19:59 EST 2001 | Ben

Hi I have question about thermocouple type use for Super M.O.L.E. I found in some article that type K T/C (Nickel-Chromium vs. Nickel-Aluminum) may suffer from temperature cycling hysteresis at above 250 degree C and also diffecult to solder. Now
