We perform process studies on all manufacturing processes to verify process capability and to provide additional input for process control, including those for special charcteristics.
CPK is a statistical tool, to measure the ability of a process to produce output within customer's specification limits. CPK is used to estimate how close you are to a given target and how consistent you are to around your average performance. Our customers usually wants a CPK of 1,33. The higher CPK value, the better process.
The Picture shows the range of our CPK. Nothing lower than 1,6.
With this in mind, we can trust that our manufacturing process is capable and meets specification limits.
