How do you assure you "have squeegee pressure and speed controlled"? Search the fine SMTnet Archives for background on measuring paste thickness.

The Alpha metals Hi Check 500 is used to measure paste deposit thickness. The paste height is found from a micrometer reading determined by focussing a beam of light on a track adjacent to a paste deposit and then onto the solder paste. I've measure

We use the ASC vision master 212, our customers wanted a height and volume measurement rather than an inspector doing a visual. We have added this machine to our process, checking height on many preprogrammed locations then this generates a X bar and

Just how cold do you store your paste? And what are your solder paste reps like? Here they fall over each other giving support for their paste. And have you seen the problem with flux separation or have you only heard about it?

At a previous location we used the Semco cartridges. Occasionally the operator would have to scrape down the stencil and knead the paste back in. That would keep the paste on the edges from drying out. It was just standard procedure.
