Dear Experts, Need your suggestion on the minimum tension to be maintained in the SMT stencil. Presently we are maintaining the 30 - 50 N/cm2 at the 4 corners of the stencil. And not considering the center of the stencil into consideration.. Is t

We have had some success printing 20mil pitch with our IIT Proframe. It takes some babysitting, and you don't want your operators to be changing these things out every hour or you'll be buying lots of them. Pulling tension in one direction gives r
