Tony Although I agree in principle with Dean that 45 Degrees would be ideal, most of the squeegees I have worked with have been 60 Degrees to the stencil surface. This seems to work best with metal squeegees when printing HASL boards, because the sl

Change times for the Rheo pump are probably a little slower than just swapping blades. You have to hook up the sensors & air lines,remove the bottom cover + charge the pump to get it to operating pressure before you can print. I would guess that if y

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

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"

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

Good morning, Thank you for assistance. I�m not so experienced with MPM maintenance. Explain me please what is the difference between �squeegee down force� and �squeegee pressure�? Squeegee pressure is set so 5-6 Kg. How can I check squeegee down fo

metal blades scraping against a metal foil; do it enough times and any stencil will look like that. It's possible the squeegee pressure is set too high, exacerbating the condition. Try reducing squeegee pressure a little at a time, making sure you
