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.

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 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

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 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 ?

we have a static problem with 0603 led when removing the plastic retainer from the tape and reel. same problem with the feeder causing reject and bad placement. is there someone having the same problem? and how to fix it. thank you

Hi, I am taking a survey. How many CP6/CP4 feeders should an experienced technician be able to calibrate and PM in an 8 hour shift ? Exclude major repairs. Just cleaning,lube and calibrate. We have implemented a full time feeder technician and I wa
