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

Several points: * Consider that your Cpk is probably different for both placing large and small components. * Probably your routine placement rate SB the speed you use to monitor the accuracy of your process. * Some people use a calibrated glass test

We are using the tapered nozzles.

Make sure the lights are clean and bright. Are you running at 100% speed?

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

Hello Sr.Tech, There have been two types of nozzles made by Fuji for 0201's one was a 1mm tapered to .4mm and the other has a straight .4mm tube. Has one superceded the other and if you have used both types, did one work better than the other? Asking

Hi, What is the expected reject rate for capacitors on a CP643 machine. I estimate that we are dumping around 1 in 20 on average. I have played around with lighting levels,vision types etc. Nozzles are in mint condition. Can anyone offer any advice

Do all 0201's reject at the same rate? If even 1 P/N has a lower reject rate this can point towards a feeder problem. I have had a similar problem on a CP-IV-2 with 0402's that was caused by feeders. If all reject at the same rate it can be the PD o

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

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
