I also never heard of that. Even if you measured the stencil tension what would be the spec be and how would that even relate to quality. Other than the stencil just flopping around I doubt that minor changes in screen tension are going to change any

I used this for a couple of weeks some years ago, I was able to detect some issues whith some stenciles, but I did not use it for a long time, it may help you.

Manoel, We have never heard of such a request from a customer. I can't say that we have ever had issues with stencil tension unless we were using frameless foils or the binding came loose.

This is a requested point from some customers. It's part of the audit check points. But I agree it´s important for the process. You can garantee the stencil is in a good condition after many time using it. If your stencil looses the tension, you can

| 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 som

I hate to say this but in all probability this wont work. I have built real strain gages and they depend on the change(Co-effiecent) of resistence with strain(or Stretch). since you are connecting you elements up with copper wire it will frm part of

Hello all! For my mechanical engineering study I want to etch a strain gauge in the Wheatstone bridge configuration in a copper layer of an PCB. The goal is to measure the strain occurring in an PCB even during the press process! We can measure with

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, I just want to know how to measure the strength of a 0603 after it's cured, we are using Heraeus PD944 with a 30-7 mils stencil, glue depositions looks well, but I don't know how to measure it? Thanks
