poor print definition

Hallo all, I have recently had possibility to work with DEK265. I have met with problem poor print definition (no sharp edges). I used stencil 150 thickness, metal squuegees. I moved than the same stencil, squeegee and parameters to DEK nifinty and

Hi Mark, Not to be condescending, but is your 265 camera in focus? I've seen one instance of this. If it�s not the camera, and you are sure all your other parameters are good, , then poor definition can be from bad snap-off or bad gasketing. Snap

Please describe what was found to be optimal print parameters. I am also interested in hearing about stencil and design layout considerations. Thanks, Kevin

the viscosity of the paste is too high, printing parameter is not the problem. did you use old solder?

Barry, If you are looking to set up a documented process with set parameters you might think about performing a DOE based on the parameters you can control or change. With any measurement device you should be able to log the info gathered so you ca

hello evryone. I am rleatively new to smt production. Though we have been successfully running pcb assy's and getting very good solder quality we are trying to get some proccess control parameters set up for our printing process. We have a semiauto s

Ellaborating on Evtimov's answer: - solder paste type, think about solder granulation and viscosity. Both of these will directly affect print quality if wrong print parameters used. You will normally find recommended print parameters on the solder pa

Printing smear

Hi, I'm facing smear after printing on DEK288 using reverse squeegee at the edge of panels. I've checked the fixture, printing parameter, stencil, solder paste. What else can I do?

Solder Paste Printing

I am working with a CM in Taiwan and we are seeing significant differences between the paste printing bon the forward stroke vs the backward stroke. Print parameters are the same (pressure, speed, snap off speed) but there is a significant difference

Printing for 0402

Electronics Forum | Mon Oct 27 09:54:40 EST 2003 | John

We're just now beginning to see 0402's in our designs. Can anyone make recommendations on stencil/aperture designs and print parameters? I'm seeing skips on a small number of joints on these parts. Thanks in advance, John
