What Exactly is a Single Sided PCB?
A single sided PCB (sometimes called a single layer board or 1-layer circuit board) has just one layer of copper on top of an insulating base material like FR4, aluminum, or polyimide. It’s a cost-effective option for simpler circuit designs, as all circuit traces, pads and electronic components are placed on one side of the board, with no internal layers or opposite-side routing.
Because there’s only one conductive layer, these boards are easy to design, low cost, and best suited for low density designs including lighting modules, power supplies, and control units. The board structure typically consists of a copper layer, solder mask, and silkscreen, laminated onto a single insulating base.
How Do Single Sided PCBs Work?
Signal Processing Functions:
The copper network enables the following functions within single sided printed circuits:
- Signal amplification: Raises voltage or current levels for output strength
- Signal filtering: Removes unwanted frequencies or electrical noise
- Signal modulation: Encodes data onto carrier signals for transmission
- Power distribution: Delivers voltage and current to each electronic load
- Signal switching: Opens or closes pathways in digital logic operations
Component Integration
Electronic components such as resistors, capacitors and ICs are soldered directly onto copper pads. The substrate offers structural support, while copper traces on the single side of the PCB provide all required electrical connections.
Isolation and Protection
The solder mask layer prevents shorts by insulating adjacent copper features. Solderable pad areas remain exposed to allow component mounting. This ensures stable circuit behavior in varying environmental and operational conditions.
What Materials Do Single Sided PCBs Usually Consist Of?
Single sided PCB boards use a combination of base laminates, conductive foils, coatings, and solderable finishes. The selection depends on mechanical requirements, thermal conditions, and application specific needs.
| PCB Material | Function in Single Sided PCB | Typical Applications |
|---|---|---|
| FR4 Substrate | Rigid glass reinforced epoxy laminate; electrically insulating with stable thermal performance. | General purpose single sided PCB boards, consumer electronics. |
| Aluminum Substrate | Provides integrated heat sinking for thermal management. | LED drivers, power supplies, and high heat environments. |
| Copper Foil Layer | One layer of conductive copper etched to form circuit traces. | All single layer PCB builds. |
| Solder Mask | Protective layer preventing shorts between copper features while exposing pads for soldering. | Every single sided printed circuit board, regardless of application. |
| Silkscreen Layer | Printed reference markings for assembly alignment and component ID. | Visual aid in manual and automated assembly. |
| Surface Finish (HASL, OSP) | Protects copper from oxidation and ensures solderability at pad sites. | All production volumes; are selected based on cost and finish type. |

Single Sided PCB Manufacturer FAQs
What is the highest copper weight available?
WellPCB single sided PCB manufacturer offers single sided PCBs with copper thickness options from 0.5 oz to 5 oz.
Standard production typically uses 1 oz or 2 oz copper for balanced conductivity and solderability. For power supply and automotive applications, heavy copper PCBs up to 20 oz can be fabricated using specialized press and etching processes.
Are single sided PCBs suitable for high-frequency designs?
In most cases, single sided PCB boards are not recommended for high frequency designs requiring controlled impedance, shielding, or signal layer isolation.
But, for low frequency analog, power distribution, or LED lighting circuits, they offer a reliable and cost effective PCB solution.
What surface finishes can I choose from?
Available finishes include lead-free HASL, OSP, immersion tin, and immersion silver, each with specific strengths in terms of cost, flatness, and thermal durability. Selection depends on volume, environmental requirements and whether RoHS-compliant or lead free assembly is needed.
Can single sided PCBs be panelized for production?
Yes, WellPCB supports panelized fabrication of single sided PCBs to enable gang-run builds and automated assembly. Panel files provided by the customer are reviewed during the DRC verification process to confirm suitability for manufacturing.
How is heat managed in single sided PCB designs?
Single sided PCBs manage heat through proper substrate choice and copper thickness. For high power circuits like LED drivers or power supplies, aluminum substrates with dielectric insulation help dissipate heat.
Wider traces support higher current, and thermal loads should be spaced across the board. Solder mask color affects emissivity. Without inner layers, thermal vias are not possible, so passive cooling or external heat sinks may be necessary for continuous high-power use.
