Printed circuit boards (PCBs) are an essential part of modern electronic devices, providing a platform for the placement and interconnection of electronic components. There are several layers involved in the manufacturing of PCBs, each serving a specific purpose.
Signal Layers
The signal layers are the primary components of PCBs. They consist of thin copper sheets and are used to carry electrical signals between components. The number of signal layers depends on the complexity of the circuit and can vary from one to many.
Internal Planes
Internal planes are the layers of the PCB that lie between the signal layers. They are used mainly for power and ground supply. These layers can either be solid or use a mesh-like pattern to distribute power through the circuit board effectively.
Mechanical Layers
Mechanical layers provide mechanical support to the PCB. They are not used for electrical purposes but for maintaining the structural integrity of the circuit board.
Solder Mask Layers
A solder mask layer is applied to the surface of the PCB to protect the copper layers from oxidation and contamination. This layer is usually applied over the signal layers and internal planes.
Silkscreen Layers
Silkscreen layers are applied to the surface of the PCB, providing clear and concise labeling of the components on the PCB. These layers are used to indicate the placement of components and provide instructions for assembly.
System Layers
System layers manage the configuration and arrangement of the PCB components. These layers contain information regarding the placement of the components, the routing of electrical signals, and the supply of power.
Other Layers
Other layers are used for special purposes, such as surface-mount pads or test points.
