Each individual thermal profile is rated upper and lower limits on how it fits in a method window (the specification or tolerance Restrict).[six] Raw temperature values are normalized concerning a proportion relative to both of those the process indicate plus the window limits. The middle of the process window is defined as zero, and the extreme edges of the method window are ±ninety nine%.[6] A PWI larger than or equal to a hundred% suggests that the profile won't approach the solution in just specification.

On the subject of statistical Assessment, comprehending 3 sigma control limits is vital for making certain top quality and consistency in procedures. These control limits help determine any time a course of action is suffering from variation further than get more info what is anticipated, allowing for well timed intervention and adjustments.
