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 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.

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

According to the datasheet, this is a LED encapsulant, is that how you are using it? It also had a section on compatibility, which indicates that it is an addition-cure silicone prone to cure inhibition.

HI again Dave, I was wondering what kind of problems you were experiencing with the silicone tape that led you believe that it wasn't the correct tape and question the manufacturer? Were there more failures and solder issues ? Thanks

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.

Yep, especially if they are the silicon domed type that mark easy. We gang pick LEDs on our Yamaha kit, getting 12 at a time per side, but we have the luxury and volume of having multiple reels of the same components.

I have a question for any Panasonic CM 402/602 users. We run Cree XPE/XPG/XPC LED's on our machines, and have struggled for years with the lights sticking in our nozzles. We have two types, I believe both designed by Cree, one picks the light up by
