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

Wister, I agree with the other comments as far as challenging the customer, and minding proper height/width or better yet area aspect ratios. Let's assume you need to go with a .012" stencil for arguments sake. Talk to your stencil supplier about h

On SMTnet, we've discussed the the frailties of controlling paste height, when volume is a more telling measure. Sometimes if you seperate too quickly, the paste tries to stay attached to the aperture walls. This creates a 'U' shaped deposit with r

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

What's important in stencil printing (which differs from screen printing) is providing a consistant volume of paste at each interconnect. The process window varies in proportion to the pitch. More than 60% of all defects are related to solder depos

I can't say that I have an answer as to fixing the mechanics of your issue. However, doesn't that machine have an auto blade height? If so, even with one blade lower than the other, the blade height should only depend on stencil height. I could be co

Shouldn't the top of the board be at the exact same height as the top of the side clamps? Why are the clamps holding the stencil up off the board?

It's been a while but I believe the UP2000's should have a calibration for the squeegee height as well. I think you log in under the Calibrate or Maintenance then that should give you access to the menu you need. Once you find it I'm pretty sure it w

UP 2000 is a good printer. Spares are normal - blades, stencil/board light bulbs, the over head flourecent, get new conveyor belts. Take the cover off the tactile sensor and make sure it's clean also. Other than that it should be a work horse.

Question: Can an MPM UP 2000 HI E printer recognize Right or Left justified screens? Please let me know. Brad Jakeway Cardinal Circuit
