Abstract
a printed circuit board comprises a glass layer with a first surface and a second surface opposing one another along a thickness direction, and a side surface connecting the first and second surfaces. A metal layer is disposed on the side surface of the glass layer, and a first insulating layer is disposed on the first and side surfaces such that it covers the metal layer. This configuration enhances electromagnetic shielding and mitigates crack propagation in the glass layer, thereby improving the reliability of the printed circuit board.

A printed circuit board, comprising:
- a glass layer having a first surface and a second surface opposing each other in a thickness direction, and a side surface connected to the first surface and the second surface;
- a metal layer disposed in a first region of the side surface of the glass layer;
- and
- an insulating layer comprising a material different from that of the glass layer and disposed in a second region of the side surface of the glass layer.
A printed circuit board, comprising:
- a glass layer having a first surface and a second surface opposing each other in a thickness direction, and a side surface connected to the first and the second surfaces;
- a metal layer disposed on the side surface of the glass layer;
