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.

LED sticking in nozzles are such a problem, seem everyone has issues with this from time to time. Don't want to advertise who's nozzles worked best but will answer you back if you drop me an email.

Hi, This is for a Universal GSM1. Is there a way to make a nozzle rotate to the same point before picking the next component up. It is because we are trying to pick & place a rectangular component (Luxeon Rebels) with a rectangular nozzle. The nozzl

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

yes, we are also picking it up on the flat part of the component. So we won't damage the dome. Just as discribed on the assembly and handling data sheet. Because the component is picked up out of the centre, it gets instable when picking it up out of

We have issues with the Philipps Luxeon Rebel LED where the part sticks to the cover tape during advancement. This causes the part to get flopped around in the pocket or the component gets dropped and damaged when the feeder advances. Has anyone ex

I worked on a nozzle for one of these LEDs in the past. I seem to remember that there are raised surfaces outside the pick up area. Be sure your nozzle is not hitting them, if so you will lose vacuum. A rectangle shaped nozzle would maximize your abi
