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

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.

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

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

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

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

The tension depends on the thickness of the stencil. Exp: stencil of 100µm => tension must be higher than 33N

Hi Team, what we have observed is that tension basically at the center of the stencil is less . And it directly depends on the number of aperture opening we have . More the opening less the tension. But there is no supporting document for the same

I got question on is there any variance for thickness of stencil with respect to stencil tension. Is ther any guideline for it.
