ENNOVI introduces automotive 10Gbps+ Ethernet connector with press-fit interconnects
19 March 2024
ENNOVI, a mobility electrification solutions partner, has introduced ENNOVI-Net, a customizable automotive Ethernet connector solution supporting 10Gbps operation.
The ENNOVI-Net connector designs have a standardized USCAR interface. However, what makes them different from existing products using this interface is that ENNOVI-Net has press-fit pins as opposed to through-board solder pins. This patent-pending innovation thereby completely avoids the need for soldering.
By having access to press-fit interconnects, automotive customers are presented with a far simpler and faster assembly process, with a much lower risk of errors occurring. As solder usage is eliminated, there are no problems caused by variations in the amount of solder paste applied (and the capacitance associated with this).
In addition, the shortness and lower capacitance of press-fit pins, compared to through-board solder pins, means resonance is reduced, the company says. For both of the above reasons, greater signal integrity can be achieved.
Additionally, a press-fit strategy supports manufacturing operations to be conducted in a socially responsible way, with minimal impact on the environment in comparison to soldering processes creating solder fumes during assembly.
The ENNOVI-Net Automotive Ethernet connector design solution allows for customization to accommodate specific board- and connector interface positioning enabling integration into final applications. Consequently, based on ENNOVI’s large offering of released press-fit pins to most of the largest automotive Tier 1 suppliers, their specific press-fit pins can be accommodated. A -40 °C to +105 °C operational temperature range is supported by ENNOVI-Net connectors, along with ≥ 25 mating cycle durability.
The automotive-grade ENNOVI interconnect is designed to be employed in numerous applications such as ADAS ECUs, Zone Controllers, Radar Housings, Sensor Housings, and HV Powertrain controllers.
I have worked on cars with press fit pins in circuit boards for connectors. They have a tendency to fret and loosen up over time. Not saying soldered pins don't have issues, but I see lower reliability in this design.
Seems cars are getting worse and worse for long term survivability by design. Cheaper for manufacturer to build does not translate into cheaper to buy or maintain for end user.
