Coincidence? I just finished a glass calibration this morning on a P&P machine. Excellent tool for precision calibration. Takes the guess work out of the process. I would disagree with Cal's assessment. His calibration methods may work to suit h

Thanks Steve for your rather colorful and sarcastic input. If I correlate your asteroid assessment with what our QA Departments data(that tells us we are experiencing this problem about 5% of the time and I am guessing higher when we are forced or re

Dreamy "Ball rolling"? Are you a bowler? My nephew does the audio for the ESPN2 production of the professional bowling tour. Search the fine SMTnet Archives for discussion on assessing cleaning machines. For instance: http://www.smtnet.com/forum

On one hand, maybe National Aeronautics and Space Administration standards are a good starting point to establish standards for ruggedized manufacturing practice. Look here: http://workmanship.nasa.gov/wkstds_nasa.jsp On the other hand, as you say

First, let us pause for a moment, bow our heads, and say a small prayer for Ill. Second, the only thing that is absolutely necessary is to do some things that make your customer feel that you're smart and did a comprehensive job of assessing your ne

We use a Charge Plate Monitor (CPM) tp monitor the balance of our ionizers, according to ANSI ESD STM3.1. Maybe you could use a CPM to assess the ionizing radiation in your plant. The more we think about it, we feel you could use a Geiger-Mueller (G
