Martha,
        You're not trying to whack the competition, are you? (hehehe).
The Teka connectors have a solid solder deposit that is carefully
matched to the pin/hole diameters to provide the right amount of solder
without excess. At reflow, the surface tension keeps it at the
connection and prevents it from wicking further down the pin.

Steve,
        Did you check Teka's web site yet? They also have a hot air
fountain (from Zephyrtronics, the ChipQuik folks) specifically designed
for the PC104 connector that works great, and eliminates the problems of
them long 'ol pins dangling down during reflow. It's worth the cost if
you're going to be doing much of the PC104 style.
