Hi, We are having some serious issues with placing the Luxeon Rebels. The problem is caused by the components sticking to the tape. We don’t know what causes it, but I remember to have read something about components sticking to the tape on this For

We have found that the lenses on the Rebels have are gooey and sticky. We put a little bit of WD40 on the shutter part that contacts the lens. Just a little bit. Basicly, put a drop on and try to wipe it all off with a paper towel is enough.

Siemens recommended Special nozzle-03070148 and provided GF to place this component using Siemens s-25/27. It worked fine in the beginning but after a while we saw droppage. So we moved the set-up to F5 machine which is slower. Their recommended G

Hi Does anyone place the Rebel ES? It is the same as a Rebel except it has a raised bit near the edge of the flat area. I normally pick up the Rebel in the flat area using an 0805 style nozzle (Samsung CP45 CN065) but this raised bit makes it unrelia

Hello, We are having some difficulties placing the luxeon rebel LED's. It doesn't matter what nozzle's we use, we cant run our P&P machine's on full speed without the rebel's dropping on the PCB in stead of being placed accuratly. Therefore I would

Thank u for al of the reactions. I'm wondering if there are other manufacturers that use rectangular nozzle's. Because when I look at the LED when it's in the reel, I doubt it could get picked up like that. I seriously doubt that there is anyone he

Where on the component are you picking? Picking on: * Lens is probably not a good idea * Next to the lens is probably better

I think we aim for the DOT on the flat. If you get too close to the lens, the taper on the nozzle hits the lens, and you don't get enough vacuum. There is not much room for error on pickup.

Depends on what you mean by full speed. We run them Full Speed on our Quad IIC, and IVC. But those aren't as fast as newer machines. I assume there is a speed at which the vacuum just won't be able to hold on anymore.
