Mechanical stencil foil tensioning

Has anyone used the mechanical stencil foil tensioning system from certain company that eliminates using stencil frames and epoxy & mesh? Any comments on whether it's worth looking into? We go through product revisions like we go through clean sock

There's a lot of parameters to consider in defining stencil life cycle. Average squeegee pressure used, in-process cleaning frequency (auto and manual), physical appearance over time, tension reading over time, and so on to decide how many print cycl

At least there are method on detection of stencil replacement before it really fail which can safe line down.

George, No it does not make sense to measure the tension on a mounted foil, however, if you wish to please your customer you might want to find a tension gauge that measures in mils of deflection. In the beginning, screen tensions were all measured

Can anyone tell me the formula/method to determine the amount of weight that solder's surface tension can support. (ie: Maximum weight of components soldered onto a bottom side of a board during a top side reflow on a Paste/Paste process). Thanks, S
