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

Feeder is brand new. (Checked cal. even though it was new) Lighting is good. Machine is in perfect cal. Nozzles are brand spankin new from Fuji. I was able to lower the reject rate considerably by playing with the offset and gain. I am placing caps

Also Try: http://www.airliquide.com/en/business/industry/electronics/expertise/tech_papers.asp you can also search the airliquide site for "PPM" once in the electronics section Cal

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

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

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

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

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.

We are a high mix low or middle volume production. We are using 3D AOI MIRTEC. How to reduce the false cals. Every batch we are adding more samples to the program but we can't able to reduce the false call ratings. Suggest how to control the FALSE ca

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
