In the world of electronics, PCBs (Printed Circuit Boards) are the foundation for any device. Among the many types of PCBs, the 4 layer PCB stands out for its versatility and complexity. In this article, we’ll explore the world of 4 layer PCBs, their stackup, advantages, and how MorePCB, a leading EMS PCB manufacturer, can help you create the perfect 4 layer PCB for your project.
Basics of 4 Layer PCB Stackup
The Importance of Stackup Design
The stackup of a PCB is the arrangement of its layers, which play a critical role in the performance and reliability of the final product. A well-designed 4 layer PCB stackup ensures proper signal integrity, power distribution, and thermal management.
Common Stackup Configurations
There are several 4 layer PCB stackup configurations, but the most common ones involve two signal layers (top and bottom) and two internal layers (power and ground). The power and ground planes provide efficient power distribution and reduce electromagnetic interference (EMI).
Advantages of 4 Layer PCB
Improved Signal Integrity
A 4 layer PCB provides better signal integrity due to the presence of dedicated power and ground planes, which minimize signal crosstalk and noise.
Enhanced Power Distribution
The presence of dedicated power and ground planes ensures efficient power distribution and stable voltage levels throughout the PCB.
Compact Size and Weight

4 Layer PCB allow for more components and interconnections within a smaller space, resulting in reduced size and weight.
