Barry, If you are looking to set up a documented process with set parameters you might think about performing a DOE based on the parameters you can control or change. With any measurement device you should be able to log the info gathered so you ca

Thank you Russ for the information. One more clarification- I found that the %metal content in lead free paste is in the range of 88-89.5 whereas %metal content in Sn-Pb paste was 90% in general. What is the reason behind this reduction of %metal co

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

I've spoken with a number of Engineers about this subject and there didn't seem to be a consensus number. In my own experience, I found that we were replacing the stencils after approximately 30,000 print strokes. In my predictive maintenance spreads

Of course I forgot to mention that the number will vary based on the type and thickness of stencil that you're using, type of squeegees, board support, print pressure, and speed.

Well the stencil in question have shield components. And this stencil sometimes doesn't even reach 10,000 strokes.As compared with stencil that does not have shield components, the life span seems to be lesser considering that same squeegee, print pr

This is my attempt at beating the "Fuzzburg 7" translator used on the SMTnet Forum that mashes everything it sees. Below the next paragraph are three paragraphs,each with a common numering sequence, where each paragraph represents the columns of a t

Sould anyone explain me pros and cons of stencil and screen printing and the advantages of using a screen printing over stencil printing

Hello. There is been a lot of talk about thick plastic stencils vs. metal stencils for adhesive printing, but how about thin plastic stencils? We used to use a very thin plastic stencil (from loctite) with printgap (=snap-off) to adhesive printing

Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)
