US Patent 6,966,795
Flat contact leads provide a large surface area for
reliable solder joints. The solder retention devices
(SMT anchors) provide an exceptionally high retention
force for the terminal block to the PCB. The most
significant benefit of this design is the protection it
provides to the solder joints against stresses
encountered in field-installations. In terms of co-
planarity, tolerances of 0.2 mm or less are present for
2 to 6 poles, and 0.3 mm or less for 7 to 12 poles. The
elevator style contacts ensure a reliable electrical and
mechanical interconnect solution. This lead coplanarity
and the retention devices create a solid connection
resulting in high process yields with no open circuits
and high infield reliablity to human factors in use,
installation and maintenance. Material will handle
reflow temperatures well without deforming or melting.

Application
You can now convert one more component on your
board to a genuine surface mount. You can increase
packaging and component density, use both sides of
the PCB, reduce and eliminate set-up costs and
simplify and streamline your processes. Flat contact
leads provide a large surface area where screw torque
is not transmitted to the solder joint, and integrated
solderable retention devices ensure in field reliability
in thermal cycling and protect against human factors
during in field use. These solder joints have the
strength and the shape required to make a
consistently safe and reliable field-proven connection
that meet application and regulatory requirements.
The elevator-style-clamping mechanism allows an
almost unlimited number of connections and
disconnections of the wire.
