Interesting - anyone know the patent number for that? I remember Rolf
Strauss the inventor of wave soldering describing such a process to me 20
years ago while we were having lunch in London. I believe he actually did
take out a position but in true style over lunch did indeed sketch it out
for me on the back of a napkin...........

Subject: [TN] Solder Jetting

This technology was first publicized around 5 years ago.  It uses a droplet
dispenser head to "spit" molten solder at the circuit.  I think it didn't
take off because better technologies for wafer bumping were developed.

Has anyone in TechNet tried to use this technology?  It was put on a Mydata
about 4 years ago.  Seems like it might be good for prototyping--deposit
solder and then use a spray flux.  Patterns could be set up which assisted
with "nesting" BGAs.
