| I am currently looking into ways to decrease SMT changeover times. I work in a high mix-low volume factory. We use Fuji CP's and IP's for SMT production. I would appreciate hearing from anybody that has some proven methods for reducing setup/change

Actually, we calculate it BOTH ways, and track each of the two times. TOTAL changeover time starts when the last board of the previous run enters the oven and stops when the first board of the next board enters the oven. (Much the same way you would

We are in need of a small SMT printer able to double sided boards with an emphasis on fast changeover and the ability to have board supports. Our typical lot size is 1-20 pieces of rigid boards with technologies down to 0.5mm pitch and 0201's.

Hello, We measure changeover time from when the last CCA leaves the pnp to when the first piece of the new job leaves the pnp. Our average is 20-40 minutes per changeover and we have 6-14 changeovers a day"depending on job size and components per C

We currently have a single SMT line consisting of a Sanyo chipshooter in line with a Siplace 80F4 and we are soon going to install a odd form placement machine (probably JOT) into this line prior to the oven. This means going to intrusive reflow, whi

Stephen, That's true and I am going to include the reflow time in our changeovers. That way if its taking to long to change the oven temperature it will show up in our metrics. I agree, if we miss a step in the changeover process our metrics will be

You could start by putting together a matrix of P/N's vs product. This will tell you which parts are common with most of your jobs. These would then become part of a fixed feeder setup that would stay on the machine. (These will probably be mostly R'
