2. Press fit technology
 Pressfit technology offers a compliant
connection between a PCB with a plated
through-hole and a single pin or a connector.
 Press fit shape design is a technology
introduced to eliminate the need of
soldering process.

16. Test criteria
 Contact replacement :
LOUPOT EON compliant Press-fit can be replaced
2 times (3 insertions).
This operation can be realised by hand directly,
but with high precautions. Indeed, this action must
be done with an angle less than 5° around the
terminal axis and without any rotation.
 Climatic and vibration tests :
The electrical comportment is
qualified by the variation of
contact resistances, before
and after tests. This variation
doesn’t exceed 0.50mΩ.
