Chip placement pressure check.

Start with a load cell (force sensor), you will need one that can handle the force range you will be placing. Someone please correct me on this if I'm wrong but I seem to recall that placement force runs in the range of a couple hundred grams. Chec

DEK Screen printer calibration - print offset issue

Electronics Forum | Thu Mar 30 10:54:48 EDT 2017 | emeto

If you use the calibration plate and stencil, that should fix the problem. I think that you are not saving the result from the calibration test. Double check manuals and probably with DEK technician, but it sounds like you are missing a step.

DEK Screen printer calibration - print offset issue

We have a 2008 DEK horizon 03i this machine has been a very reliable system. we are having an issue with the print being offset in the x .2mm I have run 4 different boards - same issue on all. same offset. i can print the board 10 times over and

poor print definition

We assume your stencil is clean. So, try: * Reduce stencil separation speed. * Reduce squeegee pressure. If the pressure is not proper, excess number of particles are stuffed into an aperture and inner pressure / friction among particles increase, an

DEK print problem?

When was the last time your ELA was calibrated? I had an operator ding the camera some how and the machine acted very much as you describe afterwards. A camera calibration corrected the problem.

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

Measuring the real pressure applied by Squegee

Electronics Forum | Wed Apr 11 21:06:49 EDT 2018 | jacobidiego

Hi experts, I have some stencils in a bad state. Some of the marks belongs to squegee operation. I wonder if it is possible to measure the pressure that is being applied, as we can set the pressure, but we don't know if that value is real and calib

Solder paste jetting vs time pressure dispensing

Electronics Forum | Mon Jun 19 07:50:03 EDT 2023 | tommy_magyar

What I would ask before actually answering your question is, what is the smallest footprint/pad which can be pressure dispensed/jet printed? Regards, Tom.

Solder paste jetting vs time pressure dispensing

Electronics Forum | Mon Jun 19 10:30:30 EDT 2023 | smtusa

Jet printing can reach 80um, whereas contact dispensing is 0.3mm I believe. 0402 pads are 0.6x0.5mm.

Standard for Stencil printers edges pressure

Look at your paste specs, they give you recommended starting points relating to speed and pressure. Dave F is right, it is usually about 1 pound per linear inch of squeegee length. Speed for finepitch printing should be started at about 1in/sec. T
