Up to 25Gbps! Verification completed for high-speed transmission Floating structure Board to Board Connectors 10143 series "OIF CEI-28G-SR"

On August 24, 2021, IRISO Co., Ltd. (Headquarters: Yokohama City, Kanagawa Prefecture, Representative Director: Hitoshi Suzuki) has verified the high-speed transmission Floating structure Board to Board Connectors "10143 series" to support next-generation applications. , completed verification of transmission speed 25 Gbps with "OIF CEI-28G-SR" standard.
As a result, the 10143 series achieves both high-speed transmission of 25 Gbps and a Floating structure with a Floating range of ±0.8 mm. In addition, by mounting power supply terminals that also function as fixing metal fittings on both ends of the connector, the connector can be miniaturized and miniaturized, contributing to the reduction of the overall size of the board.
We are currently preparing for mass production of this product, aiming for mass production in 2021.


Major features

Feature 1: Floating
Floating structureBoard to Board Connector X Y direction Since it Floating and absorbs the position deviation between the substrates, it facilitates alignment adjustment at the time of multiple connections and alleviates the stress concentrated on the soldering part. In addition, together with appropriate inducement Mating it also greatly contributes to the improvement of workability.
The 10143 series achieves a Floating volume that exceeds the pitch width. Floating 0.8mm to the X Y direction.
Feature 2: High Speed
The recent increase in the functionality of equipment and the increase in the amount of information are spurring the demand for high-speed transmission support in connection components. In addition, the increase in the high-frequency component of the signal has led to a situation where attention must be paid to minute areas that have not been a problem until now. IRISO's high-speed transmission products are optimally designed by organically combining numerous field evaluations and simulations. In addition, one of the major features is that it combines high reliability and workability by fusing Floating structure technology and high-speed transmission.
The 10143 Series is the highest class of 25Gbps in Floating structureBoard to Board Connector history * High-speed transmission is realized.
*When measuring under the OIF CEI-28G-SR standard

Feature 3: Power Contact
By arranging power supply terminals with a Floating structure at both ends of the product, there is no need to allocate power supply terminals, which contributes to miniaturization of the connector.
This power supply terminal also serves as a fixing bracket, and has made the connector as a whole smaller. This has made it possible to reduce the board area occupied by the connector.
