Right you are. Count on it taking at least an hour if you've never done it before. I think they made the pro-head way too complicated. Standard UP style heads are so much easier.

Most of pcb have white/black printing at bottom side of them to indicate the chip location. Normally, this printing are the same location to the place that glue will be mount. My problem are the glue size between the point that have printing and not

Did you check the printing head wearing time? If I remember correct the head needs replacement after few KG of paste printing this means buy new head each few days in real production quantities. Beside for prototypes they are extremely expensive to

Hey, where's the 0201s? Just kidding. Off the top of my head, I do not recall seeing results of such a test. Nonetheless, I�ll consult with my peers and let you know if we come up with something that could assist you. That said, with a few more d

metal blades scraping against a metal foil; do it enough times and any stencil will look like that. It's possible the squeegee pressure is set too high, exacerbating the condition. Try reducing squeegee pressure a little at a time, making sure you

Printing solder paste * Use single stroke, on-contact print cycle * Ensure the substrate is well supported, especially under areas of fine pitch print. * Select pressures of about 1- 2 lbs per linear inch of squeegee blade [Set squeegee pressure hig

How fast is your print head speed? I've found that I had to decrease my print head speed to get the paste to stick to gold pads. Not exactly sure why - but the ol' instincts worked well.

Yes, I calibrated the height, no error. How can I check that pressure was compensated? If we press button "continue" after some cycles of printing system will show "error".

The slower the squeegee speed the more tendency for "drag out" Raise the print speed and pressure. Rule of thumb 1.5 to 2 LBS squeegee pressure per inch of blade to start. OR try 2 passes with the squeegee.

I've heard there might be some problems when using an enclosed print head with water soluble paste. It dries out and compacts in the head. Just the opposite of what is claimed I know, but I hear it is wonderful when using no clean paste. Can anyon
