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.

Alex, I can tell you from experience it took a great deal of experimenting with settings when we first started running these. Our best course of action if the settings aren't making a difference, is the blow off. I've had it, let's say pretty high as

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

They are very finiky. If you have good solder paste, and a slight down pressure, to make sure the LED is "stuck" to the board, you should be able to place it. Pick it up on the center of the flat, NOT the lens. Even with the vacuum turned off, t

Should be do-able. Check out a couple of things: 1. Temperature tolerance of the LED's. If they can't withstand reflow, then you won't be able to do it. 2. Height of the LED's versus the travel of your pick/place. If your pick/place head won't t

I am mounting 3535 Cree High-power leds with p&p machine. First nozzle picks up the led normally and then it's placed good but after 4-5 times nozzle picks up the led like at an angle. looks like it holds the led from the side edge of the dome.
