A new patent for 3D printing of shielded conductive traces

Nano_Dimension_Dragonfly_2020_newNano Dimension Technologies, a fully owned subsidiary of Nano Dimension, has filed a patent application with the U.S. Patent and Trademark Office for the printing of shielded conductors combined in a printed circuit board (PCB).

The patent presents an innovative solution for the phenomenon of electric power loss in PCBs that are primarily used in the communication industry.

The communications industry requires high speed data transfer, where current high speed circuitry reaches speeds of 60G-100G. PCBs for this industry suffer from losses between the conductive traces (CROSSTALKS) and other phenomena arising from the multiplicity of signals. The loss phenomenon interferes with the proper function of the electric circuit and can prevent its proper function.

Nano Dimension has developed a unique 3D printing method that creates printed sheaths to shield the conductors like a form of insulated cable, and this new printing method allows the sheaths to be built into the PCB object.

This innovative approach creates the opportunity to minimize the size of PCBs used in the high speed communication space.

By selectively depositing Nano Dimension’s conductive ink, one can build a shield along the entire length of the conductor at a minimal distance. This prevents leakage and loss and is similar to the current practice of using shielded cables with the PCB externally. 3D printing allows the shielded cables to be embedded.

High-speed boards are essential to the telecom industry and are a key component of the rapid servers that allow real-time Big Data implementations.
