I'm thinking vibe feeder as well. I saw this alot on older machines (Quad IVC) vibe was set too high making parts jump around. If it is a vibe feeded, look for spillage behind the feeder base.

Definitely feeder related - we get it all the time on those package parts. If you can, slow the tact of the feeder advance a bit (if it's on T&R). We also don't catch it at placement, but at pre-reflow visual or AOI.

Crishan, You must be seeing an incredible amount of Attrition on this component if this is the case. You should most definitely be able to put in a Pick-up offset either at the machine or in the part data. aj

Is it possible to advance the feeder at shorter intervals? So every time the part is picked the feeder moves 2 times shorter movements instead of one long move? Just a thought.

oh,sorry,my expresion is not clear.the problem is that about one sixties of BGA is deviation from the proper position one line. my place machine is IP3,the part data of the BGA is okay(in my opinion),our "test vehicle" is poor just by human eyes,with

Hi All, We are not using a Vib. bowl feeder, or stick feeder, these parts are on a reel. The pick & place machine we are using is a Panasonic brand YV100X, its a single head with 8 nozzles. What we are finding is that the component package size is

Ian, The vision should recognize it; given you've got the correct Part Data. To run 0402 effectively with a CP3 you need: 1. A good, I mean real good, CP4 style feeder for 0402 (1005) 2. 0.7mm nozzles (get from second-source supplier such as WT in

hi guys the scenario is: when placing parts which required maximum speed, the cp6 sometimes missing resistors here and there, when checking part data, everything ok i notice that when the machine switching between high and low transport speed, (eg: r

You also should check to make sure you have blow off at the placing station set properly. I have seen machines with the flow control valve shut completely off not release parts properly. The parts end up in the scrap bin and the machine thinks they

If you are sure that your part data is correct, have you checked the calibration of Z origin? Are the parts leaving an impression on the paste or is there no indication of an attempted place. How small of resistors are we talking 0402, 0603, 0805?
