2 Layer PCBs | The Complete Guide for Design and Manufacturing

2 Layers PCB Structure

Our 2 layers PCB design features a complete stack-up that includes:

1. Top Copper Layer – Primary signal routing and component placement
2. Dielectric Core – FR-4 substrate providing insulation and mechanical support
3. Bottom Copper Layer – Additional routing and ground plane
4. Solder Mask – Protective coating on both sides
5. Silkscreen – Component identification and markings

2 Layers PCB Thickness

As a professional 2 layers PCB manufacturer, OurPCB offers various thickness options to meet your specific requirements:

• Standard Thickness: 1.6mm (0.063″)
• Thin Profile Options: 0.8mm, 1.0mm, 1.2mm
• Thicker Options: 2.0mm, 2.4mm

The thickness of your 2 layers PCB impacts several performance factors:

• Mechanical Stability: Thicker boards provide better mechanical support
• Electrical Performance: Controlled impedance for high-frequency applications
• Thermal Management: Heat dissipation characteristics
• Weight Considerations: Critical for mobile and aerospace applications

2 Layers PCB vs. 4 Layers PCB: Making the Right Choice

As both a 2 layers PCB manufacturer and multi-layer specialist, OurPCB provides guidance on selecting the optimal board type:

2 Layers PCB Advantages:

• Cost-Effective: 30-50% lower production costs
• Simpler Manufacturing: Faster turnaround times
• Sufficient for Many Applications: Ideal for less complex circuits
• Easier Prototyping: Quicker design iterations
• Thinner Profile Options: When space constraints are critical

When to Consider 4 Layers PCB:

• Complex routing requirements
• High-speed digital circuits
• Improved EMI/RFI performance needs
• Dense component placement
• Dedicated power and ground planes required

Single-Sided vs. 2 Layers PCB

Understanding the differences helps select the right board for your application:

Single-Sided PCB

• Components and traces on one side only
• Limited routing capabilities
• Lower manufacturing cost
• Simpler design requirements
• Suitable for very basic circuits

2 Layers PCB (Double-Sided PCB)

• Components and traces on both sides
• Significantly more routing space
• Greater design flexibility
• Better signal integrity
• Higher component density
• More challenging thermal management

Benefits of 2 Layers PCB

As a premier 2 layers PCB manufacturer, OurPCB’s double-sided boards offer significant advantages:

1. Increased Routing Capacity: Components and traces on both sides maximize available space
2. Design Flexibility: More options for component placement and trace routing
3. Compact Size: Smaller footprint compared to single-sided designs
4. Improved Signal Integrity: Better control of impedance and crosstalk
5. Cost-Effective Complexity: More capable than single-sided without the cost of multi-layer boards
6. Reliability: Proper ground planes improve electrical performance and stability
7. Versatility: Suitable for a wide range of applications from simple to moderately complex
