David,

     I imagine that Hot Bar solder methods are used in many applications
     and the following is not knocking those areas that work.

     We used the hot bar on a 68-pin in-line connector on a PCMCIA card.
     Again, not sure what your final application is!!!  Again I stress, we
     used a 68-pin in-line connector for a PCMCIA card.  Using No-clean
     paste and flux we encountered repetitive solder shorts, opens and
     insufficient solder with using the Hot Bar Method.  I came up with a
     solution to the problem and our defects at this location have
     decreased by approx. 60% and our efficiencies have increased by 50%.
     If your application is similar, I can provide you  the specifics on
     how to minimize defects and increase productivity.

     A recent SMT magazine contained an article on hot bar soldering.  I am
     searching for information on this process.

     1) Equipment and manufacturers
     2) Process
     3) Design Guidelines

     If anyone is currently using this process or has experience with it
     and could provide me with some information I would appreciate it.
