The birth of a new patent for circuit board 3D printing accelerates catching up with traditional PCB manufacturing

In March 2016, Nano Dimension, a well-known enterprise in the field of 3D printing electronics, announced that Nano Dimension Technologies, a wholly-owned subsidiary of the company, had submitted a patented technology application to the US Patent and Trademark Office. A method of printing shielded wires on a PCB board.

As we all know, the communications industry needs high-speed data transmission, and the current transmission speed on high-speed circuits can reach 60G-100G. PCBs in this industry tend to suffer losses due to crosstalk of conductive lines and phenomena caused by the diversity of signals. And this kind of loss phenomenon will interfere with the normal function of the circuit.

In response to this problem, Nano Dimension has developed a unique 3D printing method that can create a 3D printed protective layer to shield the conductor, just like an insulated cable, and the new 3D printing process can It is planted on a printed circuit board.

This patent application proposes a solution to the power loss phenomenon of printed circuit boards, and this technology is mainly used in the communications industry. This innovative approach creates an opportunity to minimize the size of printed circuit boards used in high-speed communications.

By selectively depositing nano-sized conductive inks, manufacturers can create a shield along the entire length of the wire in the smallest distance, which can prevent leakage and loss. This is somewhat similar to the practice of using shielded cables on the outside of the printed circuit. Only 3D printing technology realizes the embedding of shielded cables (printed circuit boards).

High-speed circuit boards are an indispensable part of the telecommunications industry, as well as an important part of the fast server that can realize real-time big data.
