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.

The minimal push-out force

is higher than 20N.

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.

Microsection Data : One of the most interesting points of the Pressfit Eye Of Needle

technology is the low distortion of the hole.
