Try a "cross" design across the problem apertures. So you wind up with 4 smaller deposits on the PCB (instead of 1 big one) but should be enough to hold the component. It worked for us and was much easier on the blades (they kept catching on the far

You want to use a rubber squeegee with as high as a durometer as you can get away with, order two or three sets of blades starting with the softest and then progress up the the hardest, the reasoning behind this is the softer squeegees will wear out

Tell us more about your printer. squegge blade type ,speed, snap-off distance etc... You shouldn't have to change apertures for any component based upon its rotation. the parts that are coming out good could they withstand a higher volume print? You

Simple differences. Both processes require a very similar machine platform, controlled motion, vision fiducial recognition and alignment of a substrate (PCB or hybrid ceramic) to the "image", the image being either a stencil (hence stencil printing)

I remember Metro Nozzles mentioning that they are bringing out a new "blade" nozzle soon to allow closer density placement of 0402's & 0603's than the 08MPF allows. Also noticed that you get far better placement with a 1 mil camera than a 4 mil, coz

When it comes to solder paste, you should worry about volume. Granted height is a part of the equation, but you could have perfect height and still get defects. I wouldn't get too wrapped up in volume either, unless you're evaluating stencil height

Could be a lot of things but try this, on the SPM that we have the lead screw that moves the blades up and down runs through a piece of threaded plastic. When it strips out, it starts to cause all kinds of wierd problems. The replacement part we got

I wouldn't expect them to define squeegee speeds any more than they would tell me which printer, squeegee blade, or surface metallization to use. Start at 1"/sec. and see what it looks like. Try 2"/sec and .5"/sec. and see if they're any worse or b

Thanks - the bladed nozzles work well but I'm still getting used to the best light levels to use on parts and how to get what I want by adjusting light. I think I might get some 08MPF's as they should be a good all around nozzle for smaller parts in
