Does any one have the capability to produce 50 um lines and spaces with 2
um fused solder over the traces?  Experiments have shown a dewetting of the
solder into balls on the traces, however, the wetting angle is not bad.  Is
there a physical constraint we are running into which is causing this
globbing of the solder?
