Hello everybody!! I would like to know what kind of tool do you use to analize pick-up error rate at CP and IP fuji machines? Is it special kind of software or you use some customized solutions? Im thinking about writing some kind of database based

I am surprise that you get 99.5% pick-up rate out from the HS-50, unless you are refering to 0201 chip size. I can easily get 99.8% for 0603 and 99.6% for 0402 out from a Panasonic MV2F, and these machines have no adaptive pick-up. To get 99.8% from

Yes, but you can expect a 20%+ pickup failure rate. Chuck-based alignment was so 1990's.... :)

So, to really get reliable pickup rates from new bulk feeders, I just need to replace all the chip shooters we have with more recent ones with pickup correction capability. So where is the saving? ;-) -Upside down resistors? not an issue. so what if

for reject rate depends on various parameters, Part data parameters, (Body tolerance,Part pickup & transport speed etc. ) Also depend on vaccum level, ( During the PM we need to messure pickup nozzle vaccumlevel using manometer ) According to raw mat

Those Panasonic machines should be able to tell ya pick-up rates form the feeders and shape code errors (components it doesn't recognize). You will probably get a more pick-up errors than anything else. Most of this is due to plastic tape versus pa

Don't know if you can do it on a MyData, but I have found that I lower the rate of failed pickups on our machine by altering the placement order of devices. Specifically insisting it does not attempt to pick sequential parts from the same lane. Of co

Our experience has been similar to yours. Not the best placements rates for 0603 caps. I can't tell you an exact reject rate on our machines. We program them as leaded components which seems to help a lot. Also, not using gang picks is best. You

Could also be the leads catching on the feeder or tray during pick-up. I just had a feeder catching the edge of a lead as the part was picked causing the part to shift and be rejected at severe rates.

HI, We have placed with both Fuji Qp's and Universal Gsm's. We are running a small coil now on a Gsm with a sucessful rate.The Qp done well also, but the product is not ran on a Qp line, so no true production rate has been determined.I don't feel
