what did your D.O.E. studies show you as the critical parameters? These are the ones that you need to measure. If you did not perform DOE than you probably should prior to putting an SPC chart out there. What type of measurement capabilities regar

Thank you Russ for the information. One more clarification- I found that the %metal content in lead free paste is in the range of 88-89.5 whereas %metal content in Sn-Pb paste was 90% in general. What is the reason behind this reduction of %metal co
