Do you also measure job run time? IF you don't I"m sure if the change over time is measured but not the run time then the run time will go up almost as much as the change over time goes down.

If you stop when the first completed PCB of the next run goes in the oven, wouldn't you be including the loading time for that PCB in your change over time? Wouldn't change over time be from the time your p-n-p machine stops loading the last board o

You could alternatively look at it another way - the customer asked how quick it would be to change over 20-25 feeders. All of the above machines have the capacity to hold at least double this, so the question is can you run the orignal product, w

Hi Grant, change over and set up times for the CP's depend on a few things. For one, if you have enough feeders you can have the feeders reeled up ready to go on the machine. The change over will be very quick. If you are lucky enough to o

Howdy, I have an Electrovert econopak smt II. I'm set to change over in June to SN100C. I won't be changing out anything. I'll just be purging the lead out of the solder pot with a tin bath. I don't expect there to be any problems with our change
