Positrol Plans and Logs

This book presents an unconventional, but successful approach to controlling processes during production. It explains a method by which the input variables of the process are controlled, rather than monitoring the product output variables after the fact. It contains a full description of how to design Positrol Plans and Logs, and how to linked Positrol Logs to maintain traceability of process changes and behavior during production. It details the implementation of Positrol Plans and Positrol Logs with a Solder Paste Printing process. Examples of Positrol Plans and Logs are included for a silicon wafer grinder, a screen printing process, axial insertion process, a wave soldering process, an oxide deposition process and a nitride difussion process.
