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

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.
