Mark my words; never the twain shall meet. When I had control (or at
least thought I did), I would not allow the two processes in the same
facility.

Subject: [TN] Changing conformal coating from silicone to urethane...

We are considering changing our pcb conformal coating process from a
silicone base material to a urethane base material.  Other than a
thorough cleaning of our machine, replacing material delivery lines,
complete disassembly and cleaning of nozzles, ordering new nozzles to
meet viscosity requirements of new material if necessary, are there
other concerns we should be addressing?

Mike
