Introduction to 3D Circuit Design

Traditional electronic circuits are designed and manufactured in a planar, two-dimensional (2D) layout on printed circuit boards (PCBs). While this approach has been the standard for decades, it has limitations in terms of circuit density, performance, and form factor. As electronic devices become more complex and compact, there is a growing need for a paradigm shift in circuit design. Enter true three-dimensional (3D) circuit design, a revolutionary approach that enables the creation of highly integrated, high-performance electronic systems in compact, flexible, and unconventional form factors.

What is True 3D Circuit Design?

True 3D circuit design involves the arrangement of electronic components and interconnects in a three-dimensional space, unlike traditional 2D circuits that are confined to a single plane. In a true 3D circuit, components can be stacked vertically, and interconnects can follow complex 3D paths, allowing for higher component density, shorter signal paths, and more efficient use of space. This approach opens up new possibilities for electronic device design, enabling the creation of compact, high-performance systems with unique form factors.
