Are you using extra feeder tables that you can setup off line and than just exchange for the ones you had in the machines for the previous batch? This way the Siplace should not be too bad. Otherwise for fast change and low volume you might look at m

| We are having a bridging problem with SOIC 14,16 and 20 pin devices during flow solder of the bottom side of our boards. This bridging occurs about half way up the lead between the board and the body of the IC. The chip parts are no problem. The

This will probably sound like a dumb question, but... I have a specific 1206 chip resistor that routinely ends up placed upside down on the pcb. We use Juki 750 placement machines. I normally run the machine with the auto-correct for the pick posi

I have not looked into eutectic die attach. My dies are about .012" square and could get smaller. Currently using a Epoxytech conductive adhesive. I am going to go out and look at equipment and build samples. Some vendores state they can do .010"
