For tool accuracy, you use calibration labs.

Thanks for reply, in fact, my question is how to calibrate the tool itself, it has some load spring and a gauge moving according to the tension of the mesh. I was wondering if I can make 2 different tension sets to have different comparing values, th

Thanks, I wish all SMT quality people have the same thinking.

Hi all, I have a GRUNIG G-CHECK tension measurement tool, I need to prepare a calibration report internally. https://graphcom.gr/product.php?lang=en&id=128 Measuring range between 7 and 50 N/cm Thanks for sharing any useful calibration instruction

People that measure, say 4 symmetrical points() and one in the center to get the full picture. I personally see it as a NO value added activity. If stencil changes performance - replace it.

Totally agree with Evtimov. Let the SPI be the judge, as long as your getting good prints, your stencil is fine. I had a colleague cut the mesh on one side of a stencil and it still printed fine. This was proof to management that measuring tension w

SMT stencil standard: measure the four corners and the middle, target value is 26N/CM or more

Then Z MOTOR > Then select>CALIBRATE FORCE SENSOR NOTE: you must have a tool in the head when you do this.(Without the tip/spring pushed in) After this calibration the force should drop to 0 when you push in on the spring loaded tip. 2.) Replace th

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
