I don't know what machine type you have or what the nozzles look like but we use a standard nozzle with an I.D. of either .8 or 1.5mm. We rotate and pick up the part somewhat slowly.

Has anyone developed a custom nozzle for these guys? http://www.osram.convergy.de/upload/documents/2005/03/03/14/47/LA_LO_LS_LY_E63B.pdf I've found that there is a deposit of epoxy at the base of the lens that can sometimes cause the LED to lodge in

I agree with Russ, a standard nozzle picking up directly on top of the dome. Do not go around (or over the dome) and try and hold the part from the base. Have you tried using a nozzle around 1.0-1.5mm in diameter and hold it from the tip of the dom

Thanks for the suggestions. We have been going around the dome to pick from the base. The placement machines are Panasonic chipshooters - MV2VB and MV2C. I have several problems with the MV2C. The K-type feeder plates were moved by my predeces

Clark, Which component type are you using? Deform? also, is this a domed led? and if so, are you using a nozzle with an approriate ID to seal on the body? Not every LED may be able to be placed with a 4791. Todd

Are you using a custom nozzle meant for the domed LEDs? If not, that should help quite a bit and are less expensive than you may think.

Hi all, We are having a lot of trouble with mis-pick trying to place silicone dome LEDs(3535 package) It seems that the silicone of the LEDs is sticking to the side wall of the carrier tape pocket. The vacuum nozzle would normally suck up the led an

I had the same question. We have custom nozzles made by Count on Tools. I believe we found urethane works the best for the silicon domed LEDs. Have you slowed the feed rate down on the feeder? Also adjust the top tape to the back slot on the feeder.

We have been having problems placing a domed LED with a Mydata HYDRA. The pocket that the part comes in seems to have some slop causing the part to be picked crooked. We have been playing around with different custom tools. Has anyone had similar
