A 4 layer PCB stack-up is a circuit board with four conductive layers. It offers a balance of complexity and cost-effectiveness for many electronic designs. OurPCB specializes in manufacturing high-quality 4 layer PCBs for various industries and applications.
The fabrication of 4 layer PCBs starts with core material selection. We use FR-4 or high-frequency laminates based on your needs. The process involves precise layering of copper, prepreg, and core materials. We apply photoresist, expose, and etch the circuit patterns on each layer.
After etching, we laminate the layers together under heat and pressure. This creates a solid board structure. We then drill holes, plate them, and add solder mask and silkscreen. Our advanced equipment ensures accurate alignment and consistent quality throughout production.
OurPCB offers expert 4 layer PCB manufacturing services. We combine cutting-edge technology with years of industry experience. Our team is committed to delivering high-quality boards that meet your exact specifications.

The four layers of PCB stack-up are the top layer, inner layers, and bottom layer. A typical 4 layer PCB board includes signal, power, and ground planes for optimized performance. The 4 layer PCB power plane and 4 layer PCB ground plane ensure stable voltage and signal integrity. This multilayer PCB design improves high-speed capabilities and minimizes interconnect issues.
The 4 layer board fabrication process starts with PCB production and preparing copper layers. Inner layers are etched with copper foil for circuits, followed by lamination with dielectric. Vias connect internal layers to outer layers, ensuring reliable interconnect paths. Finally, the board thickness is refined for optimal 4-layer PCB output quality.
4 layer PCB design rules focus on 4 layer PCB design for manufacturability guidelines to prevent errors. Proper 4 layer PCB layout includes HDI techniques and careful placement of vias. The 4 layer PCB tutorial emphasizes high-frequency management and minimizing crosstalk between layers. Adhering to a PCB stack-up guide ensures that the layers of the PCB function efficiently.
Prototype cable assemblies are the very important place in between PCB design ideas and interconnects. OurPCB brings prototype assemblies with PCB solutions to your tables.
