Good Morning everyone,
It is nice and sunny here in Bristol, England.
The birdies are singing and all is well...(yeah right!)
I am looking to apply process control to our three wave/flow soldering systems.
There is a lot to do here, so I am taking it in small chunks.
The first area I am looking at are the temperature related elements which are the preheaters and the solder pot itself.
I want to generate a control chart to monitor the temps of both on each machine. Readings will be taken morning and early afternoon.
Presently, I am collecting readings of each every 30 minutes so that I can use these samples to generate the UCL & LCL values
The two daily readings would obviously be entered onto the control chart and as long as they stay within the limits, or we get a trend of plots, everything will be wonderful.
I have used simplistic control charts in the past, but having read up on the various types in more detail, I believe I need an Xm-R chart.
Would I be correct or is there a better chart type that I could use.??
