I am a doer myself but with the turn around and cost on EFORM stencils I prefer to be right and starting with math is always the best way. We have played with reducing apertures even stencil thickness as low as 4 mil. On the side that this component

Hi. We are planning a production run of a board that utilises the SEMTECH SLP2710P8 8-pin device (2.7 x 1.0 x 0.58mm). The part orientation on the board necessitates that the squeegee print direction approaches the stencil apertures on the long side

You can order the glue stencil at http://www.usastencils.com They can design the opening of the apertures on the stencil in the middle of the caps so you can screen an adhesives through the opening then you will have it right on the center of the cap

I keep hearing about polyimide stencils, but what are they like in terms of registration and aperture accuracy?

Included screenshots from DEK manual, outlining stencil depth adjustment. Basically, distance from rear of the stencil to the front of the image is value needed to be set on scale when positioning stencil. There is an other way to adjust stencil, by

We have a similiar problem with kester em907, a pb free paste. You say that your AOI system picks up blocked apertures, do you mean that the printers own camera looks at the stencil and sees apertures blocked? Or, is it picking up insufficient paste
