A quick and dirty test; Take a few inches of carrier tape, peel off the cover, gently turn it upside down and see if any of the parts stay in the tape. If they do, then you know there's an issue with the tape.

Does anyone know of a web site (or other source) that illustrates the orientation of polarized SMT packages with respect to the carrier tape sprocket holes? THANKS, Doug

Are the parts kept in a humidity controlled environment ? Perhaps a little humidity is making the silicon "sticky".

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 did a test where the leds were put into a 95% humidity at 60 degC environment for an hour, and after that almost all leds would stick into the carrier tape. So, moisture might certainly play a major role in the stickiness of the leds. We placed al

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.

What was the outcome OrHorti after baking some? In the end we went with a different machine (Fuji NXT) which was able to get the leds out of the reel. After switching we still face a loss of about 0.5% but it is acceptable for now.

You need to slow down the machine for starters. Try rotating your nozzle so that the touches the least amount of silicone membrane as possible.
