hello everyone, I have issue with one of my DEK air conditioners, it starts to freeze soon after we turn it on. most probable cause is low air flow or low refrigerant pressure. does anyone know what is operating refrigerant pressure range for DEK ai

Typically freezing and air conditioners equals a low charge.

This is not an HVAC unit. This is a small unit attached to a production machine to keep the solder paste from drying out prematurely or slumping. The volume of air being cooled and desicated would be less than 3 or 4 cubic meters.

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

And I can set deposits down to 34 um on our my500. I do not have the exact numbers in front of me on the my700 or Essemtec, but they will both be better than that.

I just flew in from (insert city) and boy are my arms tired. pr: Likely, you're correct. The "pound-inch" units should have been the give-away, for us. Good catch. If this is the case, the frame fabricator would be the best source for tensioning

Are you still facing this issue? Well, I am so late to get to know this. I think you first check your evaporator coil if your air conditioner is still freezing up. It has been seen that a dirty airflow coil stops the proper flow of air through it. It

The way to determine correct pressure (in my experience) is to start out at what you would consider to be a low sq. pressure setting. You are looking for it to leave a slight film of paste on the stencil. Start increasing pressure in small incremen

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

There is no standard, nor should there be [because the IPC standards should be aimed at describing results, not the path used to reach the results]. So, your printer equipment supplier recommendations are a good starting point. Your "35-46 lbs-in"
