Product Structure and Core Materials
Single sided Rigid PCBs typically consist of the following three layers:
- Solder Mask: The solder mask prevents copper foil oxidation, while the silkscreen is used to mark component identifiers, improving assembly efficiency and ensuring compatibility with wave soldering and conformal coating processes.
- Copper Foil Layer: Copper-clad on one side, with a thickness of 1oz to 2oz. This can be customized based on current-carrying capacity and heat dissipation requirements to meet the electrical demands of industrial and automotive control modules.
- Substrate : Made of FR-4, CEM-1, or phenolic paperboard, offering excellent mechanical strength and insulation properties, and supporting a wide operating temperature range of -40°C to 85°C.
Since interconnection between the two sides is not possible, all routing must be completed on a single side, placing higher demands on routing density and layout. Electrical connections must be achieved through proper layout or jumpers during design-one of the key challenges in 1 Layer Rigid PCB design.
Technical Features and Manufacturing Advantages of Single sided Rigid PCBs
- Single-sided routing restrictions: no vias are required, and routing cannot cross, making it suitable for low-density designs.
- High pad design requirements: pads must be large enough to ensure reliable soldering and easy maintenance.
- Simple process flow: supports ±40 μm placement accuracy and is compatible with both wave soldering and manual soldering.
- Strong cost control: low raw material usage and short production cycles make it ideal for high-volume orders.
- High quality stability: IPC-A-610 Class 3 testing as standard, achieving an automotive-grade yield rate of 99.82%.
These features give Single sided Rigid PCBs a natural advantage in cost control and delivery efficiency, making them particularly suitable for prototyping, small electronic products, and standardized control modules.
For example, Single sided Rigid PCBs still play a core role in the following common devices:
- Home appliances: rice cookers, washing machines, air conditioner control boards
- Lighting equipment: LED driver power supplies, lighting control modules
- Industrial control: relay boards, sensor interface boards, instrument control boards
- Consumer electronics: audio systems, printers, vending machine control modules
- Others: calculators, charging products, FM radios, timers, etc.
When to choose a Single sided Rigid PCB?
If your project has the following characteristics, a Single sided Rigid PCB is a suitable choice:
- The circuit design is relatively simple
- Strict cost reduction is required
- Fast delivery or prototype verification is needed
- No high-frequency, high-density, or double-sided routing is involved
Whether you call it a Single sided Rigid PCB, a Single Layer Rigid PCB, or a 1 Layer Rigid PCB, it is not a compromise-it is the optimal solution precisely tailored to your needs.
One-stop service to bring your project to life STHL provides a complete process from DFM analysis to prototyping and mass production. We support European and American compliance certifications and have successfully delivered to over 60 countries.
We understand that every project must balance cost, efficiency, and quality-and the Single sided Rigid PCB is the key to achieving that balance.
