Pick and place is not my area but I did have a customer a while ago with a similar problem. He did try different nozzles and air pressure. They use Nano protek on thier stencils. He wiped the nozzles with Nano Protek and the problem dissappeared. Onl

Thanx for the feedback. The solder mask is PSR-4000 ( need to confirm this - not too sure ). If the board got in touch with the solder bath, for the contact time of 3 - 6 secs, this should not be the case for proper curing process right ?. thanx ag

Yes, I had the same problem. I ordered another nozzles, with dimension similar to dimension of lens, increase air pressure in mounter and increase place time.

We have been seeing this in the nozzles we have made. We will building all new LED nozzles out of teflon where physically possible. Many of the new Cree LED recomendations are for teflon nozzles. In some that teflon was not recomended teflon was the

1. For laser machines, there should be setting for Z - at what level you should cut measure the part in Z axis. 2. Check all calibrations are in place and passing 3. Check resistor package setup in the software - all dimensions
