Jim,
It is a gasketed head that fits right down on the stencil and delivers the
solder paste directly to the stencil, with no bulk exposure to the air of
the paste inside the stencil machine until the paste is printed.  Both DEK
and MPM offer this type of system.  Proflow is one of the trademarked names.
All the major paste suppliers provide paste in compatible containers.

Sorry... no solutions or recommendations, just a question.  I'm not familiar
with Proflow, could someone explain?

        Hi Henry!

        I've run into similar problems with the proflow system.
        We also had very good results with normal squeegees and poor results
with
        proflow.
        I started a "Design of Experiment" to figure out what the reason
could be.
        Very interesting data came out of the test , but not a solution.

        One very important parameter was deliberately not included in the
test.
        The solderpaste.
        I just wanted the system to work with our standard solderpaste.

        When the conclusion was that our standard solderpaste failed in the
        proflowsystem, I started additional test with other pastes (types
and
        brands).
        The results look very promising for now.
        Several pastemanufacturers are capable in producing a solderpaste
that works
        well with Proflow.
        Contact your current supplier and you will probably find a solution
        together.


        Best regards,
