You only need a simple subtraction and division to calculate the Z bench. Compares Different Processes Z bench serves as a tool for comparisons between disparate processes. If process A has a higher Z bench than process B, you can say it is meeting specifications better than B. It doesn’...
The pick and place and reflow systems reflect these issues by adding more and more controls to their systems, but the fact is one of the age-old processes has continued to operate within the same rules since the dawn of the SMT assembly world: The SMT screen printing. The SMT print ...
Because the defect of Six Sigma management is directly measured according to customer requirements, the measurement method is different from the traditional method, first determine the process capability, then calculate the process capability index CP, Cpk, to reflect the process capability to meet ...

behavior as predictable for these data, the computed capability statistics can be interpreted as being well-defined (in the sense that they are reliable indicators of what the process could be expected to do in the future). A minimum capability requirement for Cp and Cpk of 1.3 has been ...
2. Calculate Cpu To calculate the Cpu, subtract the upper specification limit from the mean, then divide this by 3 times the standard deviation (SD): Cpu = (USL – Mean) / (3 * SD) 3. Determine the Cpk Once you have the Cpl and Cpu calculated, you can use the smaller of these ...
There's a fundamental difference between Cp and Cpk that takes into account the mean average. To calculate Cp, you need to know the specification limits and the standard deviation. It simply tells you whether or not the production process is capable of making products within the specifications....
Soil samples were oven-dried at 105 ◦C to a constant weight to calculate the gravimetric water content. In 2014, we only sampled at the V6 stage, but in 2015, we increased the sampling frequency to include V4. However, at the V6 stage in 2015 (10 Jun for PM, and 3 Jul for CK...
