What Is a 4 Layer PCB? Definition and Basics
A 4-layer PCB is a type of multilayer printed circuit board featuring four conductive layers, designed to meet the growing demand for high-density and compact electronic devices. Unlike single-layer or double-layer PCBs, a 4-layer PCB includes two inner layers, a top layer, and a bottom layer, offering enhanced functionality for complex circuits.

Specifically, these four layers typically consist of two signal layers for data transmission, one VCC layer for power distribution, and one GND layer for grounding. The inner layers are strategically used as power and ground planes, which minimizes electromagnetic interference (EMI) and improves signal integrity—key advantages for advanced electronics applications.
At JHYPCB, we simplify 4-layer PCB design and manufacturing, offering customized solutions from prototype to full production. Whether you need a standard 4-layer PCB stackup or a tailored design, our expert services ensure optimal performance and reliability.
4 Layer PCB Stack up
Standard 4 Layer PCB Stackup Design Guide
A 4-layer PCB stackup is critical for ensuring signal integrity, power distribution, and electromagnetic compatibility in modern electronics. Typically, a 4-layer PCB consists of four conductive layers: a top layer, two inner layers, and a bottom layer. These layers are often configured as two signal layers (top and bottom), one power layer (VCC), and one ground layer (GND). However, the exact stackup can vary depending on your design requirements.
Below are the three most common types of 4-layer PCB stackups:
- Standard Stackup (Signal-Power-Ground-Signal): Top layer (signal), Inner Layer 1 (power), Inner Layer 2 (ground), Bottom layer (signal). This configuration balances signal routing and EMI reduction.
- Ground-Signal-Signal-Ground Stackup: Top layer (ground), Inner Layer 1 (signal), Inner Layer 2 (signal), Bottom layer (ground). Ideal for high-speed designs requiring enhanced shielding.
- Signal-Ground-Power-Signal Stackup: Top layer (signal), Inner Layer 1 (ground), Inner Layer 2 (power), Bottom layer (signal). This setup prioritizes grounding proximity to signal layers for better performance.
Choosing the right stackup depends on factors like signal speed, component density, and EMI requirements. At JHYPCB, our engineers can help you design an optimal 4-layer PCB stackup tailored to your project needs, ensuring high performance and manufacturability.
Standard & Typical 4 Layer PCB Stackup
4 Layer PCB Stack up and Layout Guide
Designing an effective 4-layer PCB stackup and layout is crucial for ensuring optimal performance, signal integrity, and manufacturability. This guide builds on the standard 4-layer PCB stackup configurations, providing detailed insights into layer placement, routing, and best practices tailored for your project needs.
At JHYPCB, our expert team leverages advanced manufacturing capabilities to support customized 4-layer PCB layouts. Below, we explore the three key stackup types and their layout considerations:
1. First Type of 4 Layer PCB Stackup and Layout
- Stackup: Top Layer – Signal, Inner Layer 1 – Power, Inner Layer 2 – Ground, Bottom Layer – Signal
- Layout Tips: Place signal traces on the outer layers for easy access. Ensure the power and ground planes are closely spaced to minimize impedance and enhance EMI shielding.
- Best For: General-purpose designs requiring balanced signal routing and power distribution.
The close proximity of power and ground layers improves decoupling, but a thicker core or prepreg may require careful impedance matching.
The first type of 4 layer PCB stack up
2. Second Type of 4 Layer PCB Stackup and Layout
- Stackup: Top Layer – Power, Inner Layer 1 – Signal, Inner Layer 2 – Signal, Bottom Layer – Ground
- Layout Tips: Route high-speed signals on inner layers to reduce EMI. Use the top power layer for decoupling capacitors and the bottom ground layer as a reference plane.
- Best For: High-speed applications where shielding and signal integrity are critical.
This setup offers robust EMI protection due to the shielding effect of power and ground planes, though component placement near the edges requires attention.
The second type of 4 layer PCB stack up
3. Third Type of 4 Layer PCB Stackup and Layout
- Stackup: Top Layer – Signal, Inner Layer 1 – Ground, Inner Layer 2 – Power, Bottom Layer – Signal
- Layout Tips: Prioritize ground plane proximity to signal layers for better noise reduction. Route power planes to avoid interference with high-density components.
- Best For: Complex designs with high component density and stringent grounding needs.
This configuration enhances signal quality but may limit top-layer accessibility, requiring optimized via placement.
The third type of 4 layer PCB stack up
Choosing the right stackup and layout depends on your project’s specifications, such as signal speed and EMI tolerance. JHYPCB offers tailored 4-layer PCB design and prototyping services to ensure your layout meets industry standards.

4 Layer PCB Core and Prepreg Thickness
The core and prepreg thickness in a 4-layer PCB stackup play a critical role in determining signal integrity, impedance control, and overall board reliability. The core is the central layer of solid laminate, while prepreg (pre-impregnated fiberglass) bonds the layers together, affecting the final 4-layer PCB thickness and performance.
At JHYPCB, we optimize core and prepreg thickness to meet your design specifications, ensuring high-quality 4-layer PCB manufacturing. Here’s a breakdown of their impact:
- Core Thickness: Typically ranges from 0.2mm to 1.6mm, depending on the board’s rigidity and layer count. Thicker cores enhance structural stability but may increase weight and cost.
- Prepreg Thickness: Usually varies from 0.1mm to 0.4mm per layer. Thinner prepreg improves signal coupling between power and ground planes, reducing EMI, while thicker prepreg provides better insulation.
The combined thickness of core and prepreg influences impedance matching and decoupling efficiency. For example, a standard 4-layer PCB stackup might use a 0.8mm core with 0.2mm prepreg on each side, totaling approximately 1.2mm. JHYPCB’s advanced equipment ensures precise control over these parameters for optimal performance.

Why Use a 4 Layer PCB? Key Advantages
Compared to single-layer or double-layer PCBs, a 4-layer PCB offers significant advantages, making it a preferred choice for modern electronics requiring high performance and compact designs. While 4-layer PCBs may have a higher initial cost, their benefits in signal integrity, EMI shielding, and thermal management often justify the investment. Here’s why you should consider a 4-layer PCB for your next project:
- Enhanced Signal Integrity: A 4-layer PCB stackup allows for dedicated signal layers, reducing noise and crosstalk. Inner layers can be used for power and ground planes, ensuring stable signal transmission, especially for high-speed circuits.
- Superior EMI Shielding: The ground and power planes in a 4-layer PCB act as a shield, minimizing electromagnetic interference (EMI). This is crucial for applications like telecommunications and medical devices, where reliability is paramount.
- Improved Thermal Management: The layered design of a 4-layer PCB distributes heat evenly across the board, preventing hotspots. This enhances the longevity of components, especially in high-power applications.
- Increased Assembly Density: With four layers, a 4-layer PCB supports higher component density, allowing more complex circuits in a smaller footprint. This is ideal for compact devices like wearables and IoT gadgets.
- Compact and Lightweight Design: By stacking layers vertically, 4-layer PCBs reduce the overall board size, enabling sleeker, more portable electronic products without compromising functionality.
