5 Layers PCB Board

A 5 Layers PCB Board is a sophisticated electronic part composed of five interconnected layers. Electronic devices rely on PCBs to link electronic components and establish a conductive pathway for electrical signals. A 5 Layers PCB Board is a rather straightforward correlation between price and board thickness.Thicker boards will cost more than thinner ones, but it also depends on the materials as well. To further elaborate, thicker materials can incur a higher cost to procure, laminate, and form into a PCB.

A 5 Layers PCB Board typically has the following features:

Signal layer 1 (Top layer): Top layer is used for routing the signal traces between components.

Ground plane 1: This layer serves as a ground reference for the signal traces on the top layer.

Signal layer 2: Signal layer 2 is used for routing additional signal traces.

Power plane: This layer provides power to the board components.

Signal layer 3 (Bottom layer): It is used for routing the remaining signal traces between components.
