What is 16 layer PCB?

The 16 layer PCB board is a multi-layer circuit board, composed of circuit layers and insulation layers, which are stacked and connected to each other in a specific way to form a complex circuit. 16 layer PCB board is generally used for high-end electronic products requiring large-scale signal processing and multi-layer communication, such as advanced communication equipment, industrial control equipment, military equipment, etc. Due to its complexity and high manufacturing costs, the price is more expensive.

How thick is 16 layer PCB？

The thickness of a 16-layer PCB may vary depending on specific design and construction specifications.   However, in general, the thickness of a 16-layer PCB ranges from about 1.6 mm (0.063 inches) to 2.4 mm (0.094 inches).In high frequency signal transmission, high speed signal transmission, and high power applications, thicker PCB boards are needed to increase the mechanical strength, thermal stability, and noise suppression performance of the board.

A 16-layer PCB stackup offers several benefits:

1. Signal and Power Integrity: The multiple layers allow for carefully controlled routing of high-speed signals, reducing signal interference and maintaining signal integrity.

2. Controlled Impedance: The use of multiple layers facilitates the implementation of controlled impedance traces for high-frequency signals, ensuring reliable transmission and reception of these signals.

3. Reduced Crosstalk: By carefully separating sensitive signal layers from each other and from power and ground planes, crosstalk and interference between signals can be minimized.

4. Thermal Management: Additional inner layers can be utilized for thermal management, helping to dissipate heat from power components and sensitive areas of the PCB.

5. Design Flexibility: There is ample room for complex PCB designs, including high-density component placement and complex routing requirements.

6. EMI/EMC Control: The additional layers allow for improved electromagnetic interference (EMI) and electromagnetic compatibility (EMC) control through proper layer placement and grounding techniques.

7. Multi-Layer Grounding: Multiple ground planes can be utilized to minimize ground bounce and provide a stable reference for the entire circuit.
