This is a general question just to see what people may be doing to control the stencil printing process. I am new to the stencil printing process and as the subject line states I am looking to set up an SPC plan for my MPM UP1500. Now I have a few ideas of what I can do but I was wondering what others do and how effective it has been. I'm looking for any ideas that may relate to machine functions (not limited to just MPM equipment)as well as solder paste properties. Any help or comments are greatly appreciated.
