Larry,

 I kind of recall the MyData machines having a pressure profile for parts. It can generate a "Blow Off" pressure that should release the parts. I recall setting it too high can blow around small passives.

Hi Steve,

We are not running Mycronic machines but switching to a plastic nozzle did correct this issue for us.

Good luck,

Hi All,

We have these Cree Blue LED's (PN# CLM3A-BKW-CTBVA463) that keep sticking to the $%$#&@ pick and place nozzle. We have a MY-19 and have tried changing timing, nozzle diameters with no luck. We place an amber LED of the same series that we have no problems with except for one or two once in a while.

I've tried dabbing a little Freecote mold release compound on the tip of the nozzle, and now I'm putting the reel into a 170F oven to see if baking them for a couple hours will help.

Does anybody have any other ideas that might help?

Steve Gregory
