Dave, That's exactly what we are seeing. There is a trail of components leading away from the pick point, all of which are 0402 parts. I can remove the feeder from the machine, advance a few parts into view, turn over the feeder and only half will

Our S-2000 pick & place machine has head 2 not picking up any nozzle & displays error code 8342(nozzle check error). In ANC setting, head 1 pick/put ok but not head 2; when "MANUAL" box is checked, clicking PICK/PUT then both head 1 & 2's status disp

It's normal for us when we review design. We have found that in the Y axis we need .015" whereas in the X axis we can use .005" spacing. this relates to our nozzle size vs. pickup skew etc... This wouldn't apply if there are parts taller than XXX

I would suggest accepting components only in paper tape. I have had better luck with 0402s in punched paper over plastic embossed tape. You can also pick with oversized nozzles if your vision system does not give you trouble with seeing the nozzle.

We've not seen "pick problems". We've seen "release after pick problems" caused by adhesive on components, recently. Could be the came thing, though.

Some more information is needed. Is there a machine error indicating a mispick? Or a vision error Component missing? I am not as familiar with UIC machines as I am with Siemens but here is my $.02 anyway. Try shimming the feeder under the pick up pos

Kris, Get that high speed camera in there. You have to find out what is happening after the pick point. Also just to throw in another possibility into your cause list. How about static electricty? It can effect such small components. My $ .02

Hi, Kris You mean you have checked the tape&component demension,all in spec, But could you tell me the spec of the tape cave size,I mean how about the gap between the cave and component? Do you have such spec.for 0402 Component? Please inform us
