What do you need to look?
In today's rapid evolution of self-driving technology, how many "eyes" does a smart car need? The answer is more and more. From surround view cameras and electronic rearview mirrors to driver monitoring systems, the stable return of every high-definition video stream depends on an often overlooked but vital link-the RF connector. recently,ATTENDLaunched aAutomotive Camera FAKRA-SMB RF Connectivity SolutionsIt is born to solve this core pain point and provide a solid hardware foundation for the next generation of ADAS and in-vehicle vision systems.
The core of this solution lies in the exquisite combination of two mature car gauge connector technologies:SMB PCB Board End ConnectorwithFAKRA-to-SMB Transfer Adapter。 Its working logic is clear and efficient: the SMB connector inside the camera module is responsible for leading out high-frequency signals and seamlessly connecting the FAKRA coaxial cable network of the whole vehicle through the adapter, thus opening up the "information superhighway" from the sensor to the domain controller ".
From the technical parameters, itsFrequency range from DC to 6GHzIt covers the transmission requirements of the current mainstream vehicle SerDes protocols (such as FPD-Link III/IV, GMSL 2/3, MIPI, etc.). This means that whether it is high-definition surround view images or long-distance forward-looking detection, this scheme can achieve a good balance between signal integrity and transmission distance.
Environmental resistance: IP67 and IP69K double insurance
The working environment of the external camera of the car is far beyond the imagination of ordinary people. They not only face extreme temperature differences of -40°C to 105°C, but also withstand high-pressure water gun flushing, salt spray corrosion and gravel impact. The FAKRA adapter part of the ATTEND set of programs passedIP67 (dust immersion) and IP69K (high pressure and high temperature water spray)The dual protection certification of, which provides a reliable physical barrier for cameras arranged in the exterior mirrors, front and rear bumpers, etc.
Signal integrity: double protection of EMI shielding and mechanical locking
In the complex electromagnetic environment of the vehicle, signal interference is the main cause of the image screen, lost frame. The programme adoptedEfficient EMI shielding designThe intrusion of external electromagnetic interference into the transmission link is effectively suppressed. Meanwhile,SAE/USCAR-2 and ISO 20860 CompliantThe automotive-grade locking mechanism ensures that the connector will not loosen under continuous vibration and impact, and fundamentally eliminates the risk of instantaneous signal interruption.
Design flexibility: Layout liberation for Boss-free PCBs
For the layout engineers of the camera module, space is always a luxury. ATTEND's SMB connector usesBoss-free (no positioning column) PCB designThis greatly simplifies the signal trace layout on the PCB, allowing designers to flexibly adjust the device position according to the internal space of the module, facilitating a more compact camera miniaturization design.
Successfully integrating a high-performance connector into the production process of millions of vehicles is no easy task. This requires not only technical verification, but also stable and efficient supply chain support.
AsAuthorized Distributors of ATTEND，BONCHIP (Bangjing Technology)The role played here is much more than a "warehouse" or "courier". We are the "last mile" escort connecting cutting-edge technology with mass production landing:
Full Link Product Support: We have a full range of ATTEND FAKRA-SMB connection schemes in stock, whether it is sample verification in the research and development stage or large orders for climbing and mass production, which can ensure thatFast response and stable delivery。
Deep Technical Services: Our engineering team can assist customers in interpreting complex vehicle regulation certification reports (such as USCAR-2 test rules), and provide practical experience sharing in connector selection, PCB footprint design, cable crimping process, etc. to help customers avoid common EMC and assembly traps.
Cost and Delivery OptimizationRelying on BONCHIP mature supply chain system, we are committed to providing every customerThe most competitive price and the most convenient delivery serviceLet your project win valuable time window in the fierce market competition.
With the future evolution of automotive electronic and electrical architecture to the central computing platform, the number of cameras will continue to grow, and the bandwidth, reliability and integration requirements of connectors will also rise. This FAKRA-SMB scheme of ATTEND can be applied:
ADAS Core Sensing: Front-view camera, side-view blind spot detection system.
Cockpit MonitoringDriver monitoring system (DMS) and passenger detection.
Intelligent Entry and Surround View: 360 ° panoramic view system, electronic rearview mirror (CMS).
In the marathon of autonomous driving, it is often not a certain chip with amazing computing power that determines the final outcome, but every tiny, reliable, and time-tested connection point that supports the entire perception system. Choosing ATTEND and BONCHIP means choosing a highly deterministic path from technical validation to mass production.
