A novel way to fabricate printed circuit boards without the need of expensive equipment or toxic chemicals.

About

Traditional printed circuit boards (PCBs) are fabricated using etching or milling techniques. These methods are dangerous and use harmful chemicals. Additionally, it’s a time consuming and expensive process.

Using an inexpensive 3D printer and liquid metal, the inventors created a safe and fast alternative PCB fabrication method.

The ZOG Method is a novel way to fabricate PCBs without the need of expensive equipment or toxic chemicals. The circuit board is printed using a 3D printer and liquid metal is used for the circuit traces. Circuits are packaged with plastic and sealed by default (). A single layer circuit can be seen in . Multilayer PCBs can also be fabricated with this method without the need of a multi-ton press. Therefore, the ZOG method allows for the possibility of embedding electronic components within layers, enabling PCB designs to be three dimensional.
