3 SOLDERLESS INTERCONNECT TECHNOLOGY >> Pressfit insertion rules In order to get best performance using Axon Mechatronics Pressfit, we recommend following instructions D1 minimum R PRESSFIT R D1 D2 FUNCTIONAL AREA NO PATTERN IN THIS DIRECTION D2 minimum.63 X X X X R : distance from the through hole center without any component top and bottom side D1, D2 : minimum distance between 2 Pressfit through hole center Note: for specific applications (like Pressfit mounted into connectors), the.9 ±.25 specified distance between PCB and Pressfit shoulder may be reviewed. PLEASE CONTACT US FOR FURTHER INFOR- MATION. >> Climatic & vibration test The electrical comportment is qualified 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 +,5mΩ according to IEC MAX CONTACT VARIATION BEFORE/ AFTER TEST PRESSFIT PCB PLATING MAX INITIAL CONTACT RESISTANCE ( mω) VIBRATION 1 Hz to 5 Hz 15 mn each direction 12 cycles THERMAL SHOCK -4 C to 125 C > 3 H 3 cycles CLIMATIC SEQUENCE -4 C to 125 C 5 cycles of 24 hours DRY HEAT 125 C / 18 H CORROSION H2S: 1 ±2 1-9 VOL/VOL SO2: 5 ± VOL/VOL MAX FINAL CONTACT RESISTANCE ( mω) X X X X , AXON MECHATRONICS - RELEASED SEPTEMBER ALL RIGHTS RESERVED - PHOTOS : NICKELKROME

4 >> Pressfit insertion machine c SOLDERLESS INTERCONNECT TECHNOLOGY 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 finished product cover. Axon Mechatronics offers a wide range of semi-automatic and automatic insertion machines for inserting Pressfit connections into the PCB. These standalone or inline machines can be integrated into electronic PCB manufacturing processes. To ensure optimum quality, our insertion machines integrate options to ensure good Pressfit insertion such as vision and force monitoring sensors. >> Cross section One of the most interesting points of the Pressfit EON (Eye Of the Needle) technology is the low distortion of the hole Press-in direction d Location of the microsection PCB Location of the microsection b b IEC 141/1 Measurement of the deformation a Original hole contour PRESSFIT a b c d IEC 6352 < 7 µm > 8 µm < 4 µm NO CRACK.63 X NO CRACK.63 X NO CRACK.8 X NO CRACK 1. X NO CRACK >> Applications Axon Mechatronics offers compliant pins for a wide range of applications in different industries. From inserted terminals onto PCB to stitched or overmoulded connectors, our solderless solutions will find 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 216, AXON MECHATRONICS - RELEASED SEPTEMBER ALL RIGHTS RESERVED - PHOTOS : NICKELKROME
