Hi AJ, Depends on what machines you are running, how you run them, and if you have the spare components on feeders lined up ready to go. On a volume job using CP's using both feeder banks on change over I'd be upset if they stopped for more than a

Hi, I had a question from our ISO guy asking me how I know that the paste we use is in good condition? The problem is that he saw our operator put some old paste back in a empty jar to reuse it the next day. So his question is how do you know the

Hi, How fine pitch are you going? What kind of stencil printer are you using? We had a manual stencil printer and needed to print 1-mm pitch BGA and needed to go to laster cut and electro polish at 4 thou to get good paste release. We also went 1:1
