Double Sided PCB Definition
What is a Double-Sided PCB?
A double-sided PCB, also known as a double-layer or 2-layer PCB, features conductive copper layers on both sides of a substrate, typically made of FR4 material. This design allows circuits and components to be placed on both the top and bottom layers, connected through vias for enhanced functionality.
Key differences from single-sided PCBs:
- More component space: Double-sided PCBs support higher component density, ideal for compact designs.
- Enhanced connectivity: Vias enable connections between layers, unlike single-sided PCBs with limited routing.
- Broader applications: Preferred for complex electronics like LED lighting and automotive systems.

Double Sided PCB Stack up
Double-Sided PCB Stack-Up and Design
Understanding the stack-up of a double-sided PCB is key to effective design. At JHYPCB, we simplify this process to deliver high-quality boards for your projects. Here’s how a double-sided PCB is structured:
Core Layers of a Double-Sided PCB
- Top Conductive Layer: Typically copper for excellent conductivity; gold or silver may be used for plating.
- Dielectric/Base Layer: Made of materials like FR-4, Polyimide, or PTFE, acting as an insulator between conductive layers. Metal cores (e.g., aluminum) require an additional dielectric layer to prevent short circuits.
- Bottom Conductive Layer: Mirrors the top layer, enabling circuits on both sides.
Additional Layers for Protection
- Surface Finish: Protects copper from oxidation, extending board lifespan.
- Solder Mask: Prevents solder bridges and unwanted connections.
- Silkscreen: Labels components for easy assembly.

Key Differences: Single-Sided vs. Double-Sided PCBs
One of the first decisions when designing a PCB is whether to use a single-sided or double-sided board. While both have their applications, double-sided PCBs provide advantages that may be worth the additional cost for many designs.
Below is a comparison of key differences between single-sided and double-sided PCB boards:
| Category | Single-Sided PCB | Double-Sided PCB |
|---|---|---|
| Layer Count | One conductive layer | Two conductive layers |
| Component Placement | On one side only | Both sides allowed |
| Routing | Limited to one side | More flexible, both sides usable |
| Density | Lower component & routing density | Higher component & routing density |
| Ground Plane | No continuous ground plane | Can have ground plane on one side |
| Signal Integrity | Poorer, more susceptible to noise | Better, ground plane shields noise |
| Size | Larger | More compact |
| Applications | Simple circuits | High-density or high-frequency |
| Cost | Lower | Higher |
In summary, double-sided boards allow higher-density routing and better signal integrity for space-constrained designs but have higher costs. The optimal choice depends on the specific project requirements.
How To Make Double-sided PCB？
Double sided PCB Manufacturing Process
The PCB manufacturing process is very precise, difficult and complicated.
The rigorous manufacturing process ensures the quality and performance of electronic finished products. Although the circuit board can be divided into single-sided PCB, double-sided PCB, and multilayer PCB according to the number of layers of the conductor pattern, the manufacturing process used is only different after the first layer is produced. Please refer to the double-sided PCB and multilayer PCB manufacturing flow chart on the right for more information.
Double-sided PCB Manufacturing Process：DFM –> Sheeting Cutting –> Drilling –> De-Derurr –> P.T.H –> Panel Plating –> Dry Film –> Exposal / Develop –> Etching –> Stripping –> Midd Check/Test –> Solder Resist –> Precure –> Exposure / Develop –> Silkscreen –> Postcure –> Surface Process –> Profile –> V-cut –> Final Clean –> E-Test –> FQC / FQA –> Packing / Shipping.
