What Is A 4-Layer PCB?
Mar 05,2024
A PCB is a board of non-conductive material, such as fibreglass or composite epoxy, with a layer of conductive copper traces etched onto its surface. These traces form circuits that allow electrical signals to flow between components. An important aspect of printed circuit boards is the concept of layer count. Layer count refers to the number of conductive layers in a PCB, which determines its com...
