As a connection, Pressfi t

technology offers a

favorable alternative

to soldering. A Pressfi t is

a stamped terminal designed

to be inserted into a plated-through

hole (PTH) in a printed circuit

board (PCB), in such a way that

an electro-mechanical

connection is established

without using solder.

EON compliant Pressfi t

is qualifi ed following

the IEC60352-5 tests,

and also integrate higher

requirements, such as higher

temperature and higher

cycles number.

The four Axon’ Mechatronics

Pressfi t design

has been patented.

In order to get best performance using Axon’ Mechatronics Pressfi t, we recommend following instructions

The electrical comportment is qualifi ed by the variation of contact resistances, before and after tests. All the tests are carried out one after the other, each test changing the contact resistance (increase or decrease). This variation between each test shall not exceed +0,50mΩ according to IEC 60352.

>> Pressfi t insertion machine

>> Applications

>> Cross sectionOne of the most interesting points of the Pressfi t EON (Eye Of the Needle) technology is the low distortion of the hole.

In some applications, the insertion of single pins replaces molded or overmolded connectors to reduce cost, weight and volume of the system. In this case, the connector housing is moved into the fi nished product cover.

Axon’ Mechatronics offers a wide range of semi-automatic and automa-tic insertion machines for inserting Pressfi t connections into the PCB. These standalone or inline machines can be integrated into electronic PCB manufacturing processes.

To ensure optimum quality, our inser-tion machines integrate options to ensure good Pressfi t insertion such as vision and force monitoring sensors.

Axon’ Mechatronics offers compliant pins for a wide range of applications in different in-dustries.

From inserted terminals onto PCB to stitched or overmoulded connectors, our solderless solutions will fi nd their applications into your demanding product.

Advantages of EON Compliant Pin Designs:

• Environmental compliance - lead-free plating • No separate soldering process necessary• Low thermal stress• Suitable for multilayer and double-sided PCBs• Reliable gas-tight connection, no corrosion• Reliable performance in vibration and shock• Connector can use standard plastic material for cost saving
