Hi Mark, If you are a user of stencils, you already know that there are literally hundreds of stencil manufacturers out there. If you found one that will allow such hot temperatures, I would be interested in learning who it is. However, I have only

Yes no problem here it is in a nut shell. The sponsor of my CD ROM on this process was Loctite who specifically developed a glue for the process to cure in less than 10seconds. Have a word with these guys they may even have a few CDs. PROCESS SEQUEN

I've never heard of this before. If your solder paste is at the correct temperature, and your process is under control you should have an acceptable print the first time. This sounds like a terrible waste on time and paste. Set up a DOE to prove tha

Hello, I like to hear your comments on applying SPC to solder paste printing. Specifically: - What's the most common and effective method of automated moitoring and control, Paste height/volume or printer parameters? - Actual examples in applying
