Picking the 0402 is very important- correct picking will facilitate correct placing. The quality of the feeder is key. I am not familiar with the QSA, but feeder quality is important for all picking 0402 and 0201 components.

Hopefully you dont have a lot of 0402 placements. You must have 'quality' feeder/feeders for the 0402 parts. You then should limit the picking to 1 head for those parts. Do this by assigning only 1 xf nozzle in your program. oh....Straight z-rods wi

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.

Hi All, Has anyone had any luck with gang picking the same part on Juki 2060 or FX1R's? Example: 100nf 0402, we can pick this part simultaneously from 8 feeders at once on our Yamaha's (or 12 on the old Sapphires), but on the Juki's we don't seem t

Hi, I am trying to reduce some 0402 cap tombstones. The main cause is the pad spacing is a little too far apart and the parts are as tall as they are wide .5mm I am stuck with the pad spacing for a while. All other parts are soldering well, even 0

It could be a part height issue. I have seen a case where an 0402 resistor from 2 different manufactures had different heights. If the height of your 2010 part is taller than you have programmed in the package data, the pick up head may be pushing

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
