KH This won't work if your planning on running these 2 machines together in line. The fast machine will always be waiting on the slow machine. How many Philips FCM's have you seen in line with Mydata? Don't think to hard; the answer is zero. Wh

Hi John I believe gave a good answer with cautions. The .001 or .1% is the main criteria that internationally means you are Lead-free per JEITA, the EU and NEMI. They sat around at a table and decided is how they got the .1% John did note that yo

Hi I had to poke around awhile to see what you meant. I think you were at an advanced level where IF he knew the MSL ratings of his devices he should constrain his profile within the component mfgs tests for exposure to various profiles, or at leas
