Tom,

   The real solution is special nozzles, but until you didn't buy them try
to reduce all speeds in the machine ( pick, vision, position and place ) for
the melfs and also try to increase the vacuum level. If production
requirements didn't allow increase machine cycle time then hand placement
could be a short term solution ( be careful with polarity !!! )
