We factor in 3% to our older Quad machines.

Thank you,

it seems to be an high scrap %.

I think that this % depends on the size of the component (machine loss), on the lot size (new lot set up loss) and on the number of components per reel (new reel set up loss).

What do you think abot this?

The missing rate spec. of normal machine is under 0.3%, for our experience 0.1% is normal for average, if you can maintain the machine well, like the nozzle cleaning, feeder maitain...you can keep the 0.05%.
