Yes nano coating giving the good printing, but the stencil tension is very important for the life, 1st ensure the stencil tension...

| Thanks Dave, | | But still I have the following question unanswered, in a technical point of view: | Has it sense to measure this on A system like we have now, because there are no wires that can be broken. | George: While I agree that no wires c

In the early days, we used screens made of stainless steel or polyester. Sometimes - after A period - the tension was not good, because A wire was broken. Later on we started to us metal stencils, glued in A polyester screen. even than we had sometim

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

For tool accuracy, you use calibration labs.

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
