3、key factor toimpact NTF rate.2.Based on Interaction Plot&Main Effect Plot&DOE analysis,we have got a result that CPU convert house and memory convert card using times will impact NTF rate.3.In other words,NTF rate have 84.01%variability come from CPU convert house and memory convert card using times
4、.4.Based on Regression result,we know that:Y(NTF%)=2.1514+1.185*House using times+0.9*Memory convert card using times+0.351*House using times*Memory convert card using times5.Based on DOE analysis,we have got a result that CPU convert house and memory convert card using times will impact NTF rate.Bu
5、t consider material cost,we will be settle production parameter as:a.CPU convert house using times=1750 times b.Memory convert card using times=2200 times c.Operator shift=any oneThis parameter is same as adjust current,so we will need modify using times SPEC6.Inspect sample 6400pcs,find P-value=0.0
