So I am reading about K type thermocouples in the IPC 7530 Guidelines and it says : "At temps above 250c it may suffer from temperature cycling hysteresis and may not be the best choice." Uhhh... It looks like the best choice is an N type thermocoup

I am not sure what the IPC spec is suggesting....K type thermocouples are normally specified upto 1250 C, of course there is a tolerance in their accuracy and this probably degrades after hundreds of uses through a reflow oven, but normally the accur

Sr. Tech, As far as I’m aware, most if not all, manufactures of thermal profilers offer K type thermocouples as a standard for profiling in the electronics manufacturing industry. In my decades of experience in the reflow and wave solder industry, t

Oh great!!! You do calibrations, what once a year? And NOW yer in a BIG �time is critical� rush. �Speed in reply is appreciated.� And why couldn�t you have asked this question 6 months ago? Just what have you been doing since the last calibratio

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 �

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.

Type K thermocouples are the most commonly used in the electronics industry. There are various types of thermocouple types that can be used. Examples include [Ray Prasad]: • Type K ¾ nickel-chromium vs. nickel-aluminum (most commonly used); tempera

We have a thermocouple that is basically some tc wire plugged into our reflow oven. The oven converts these voltages into the readings, but are all K type thermocouple wire the same, so would have the same exact same values sent to the ovens cpu? I

We have an internal debate whether to calibrate equipment using K-type thermocouple made out of : 1) fibreglass braided, with a 482 deg-C peak-measurement properties? 2) teflon FEP(fluorinated Ethylene Proplene), with 204 deg-C peak-measurement p

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
