Are you saying that increasing the frequency of cleaning to every 3 boards *reduced* bridging, or that it's just something you tried? I don't understand why that would help(in my experience it has reduced "insufficient solder" conditions but not brid

Hi to everyone, I will be runnig product with adhesive with a MPM UP2K, I'll use a 0.020" stepped stencil & metal blades. Is it better to use high speed for print head travel? more/less squeegee force than with solder? slow snap off? what could you r

Print then dispense in the areas you need extra paste. Why can you not use a stencil which has areas etched away around component patterns to thin the stencil down....for example a 150 micron thick stencil etched to 120 or 100 microns in specific are

We use various Zebra printers for 2D barcodes > with great success. We also have had great sucess with our Zebra's. I think that the labels that we are trying to print now on smaller than the printer (170xii) was designed to handle. I am looking f

I agree with SWAG on this. Nano Coatings make a big difference on paste release. I found when placed on the topside of the stencil, it also helps to reduce stencil wear, though others complained that it affected the solder roll, so most stencil house

We previously labelled PCBs after assembly but before AOI. Now we need to trace panels during assembly as well, so have the need to apply labels before the assembly process starts. Our stencils are thus not stepped to accommodate labels. I suppose t

I wish traceability was not part of our job. If I have to pick, I will laser etch barcodes rather than use labels. Small footprint and fine pitch parts will always hate the label when you print paste. Pick thinner labels, keep away from problematic l

How far from apertures is the label supposed to go? I'd say 1 inch is plenty. 3/4 inch might be plenty also. Do you have the ability to measure paste height? I'd say place the label on one board and print two. Is there an appreciable differenc

STARTING RANGES * Pressure � 1 pound/inch of blade (metal); 1.6-3 pound/inch (plastic) * Speed - 0.5 to 3 inch per sec [for standard pitch]; 0.5 to 1 inch per sec [for fine pitch] Your paste supplier�s recommendation is a good place to start. * Sepa

Honda, Prnting Glueisn't as difficult as it sounds, as long as you have the right stuff and a good set up. It also depend's on what your going to be placing. If your just doing 0603, 0805 and 1208 than you really only need an 8 thou or 10 thou stenc
