It sure would be nice to have some sort of group out there to exchange ideas. I have designed quite a few options that I use for quick change overs on my 5 Amistar Big Body lines. They work quite well and I am willing to share any ideas. My compan

Can anyone help? Our Solder bar suppier is discontinuing the Sn63 Pb37 solder that they currently supply us. Another company has offered us a 'direct replacement' which is their own Sn63 Pb37 solder bar. The only problem I have with this is that the

From my understanding these China OEM machines are for very specific production with low flexibility. i.e. Smaller board sizes.....machines just for memory modules. With those examples they will beable to reduce conveyor sizes, linear motor sizes whi

Hi Brandon. You should always try to optimize / "balance" your line in a way so the machine with the shortest time per placement is your bottleneck. The other machines in the line should then have a 10 - 20 sec sorter cycle time, to be able to cope
