What is PCB Panelization?

PCB panelization is the process of grouping multiple printed Circuit Board Designs onto a single panel for manufacturing. This technique is used to increase production efficiency and reduce costs by allowing multiple PCBs to be fabricated and assembled simultaneously.

Benefits of PCB Panelization

  1. Cost reduction: By producing multiple PCBs on a single panel, the overall manufacturing cost per board is reduced.
  2. Increased efficiency: Panelization allows for faster fabrication and assembly, as multiple boards can be processed simultaneously.
  3. Simplified handling: Panels are easier to handle and transport compared to individual PCBs, reducing the risk of damage during manufacturing and shipping.

Types of PCB Panelization

There are two main types of PCB panelization: tab routing and scoring.

Tab Routing

Tab routing involves connecting individual PCBs with small tabs, which are later removed after assembly. This method is suitable for boards that require a clean edge finish.

Advantages of Tab Routing

  • Clean edge finish
  • Suitable for high-density designs
  • Allows for easy depanelization

Disadvantages of Tab Routing

  • Higher tooling costs
  • Slower depanelization process
  • Risk of damage to the PCBs during depanelization


Scoring involves creating grooves or perforations between the individual PCBs on the panel, allowing for easy separation after assembly. This method is faster and more cost-effective than tab routing.

Advantages of Scoring

  • Lower tooling costs
  • Faster depanelization process
  • Suitable for low-density designs

Disadvantages of Scoring

  • Less suitable for high-density designs
  • Potential for rough edge finish
  • Risk of PCB damage during depanelization

PCB Panelization Design Considerations

When designing a PCB panel, several factors must be considered to ensure optimal manufacturability and assembly.

Panel Size and Thickness

The panel size and thickness should be compatible with the manufacturing equipment and processes. Standard panel sizes include:

Panel Size Dimensions (mm)
Small 100 x 100
Medium 200 x 200
Large 300 x 300

The panel thickness typically ranges from 0.8 mm to 2.4 mm, depending on the PCB design requirements.

Spacing and Clearance

Adequate spacing and clearance between individual PCBs on the panel are crucial to prevent damage during depanelization and ensure proper assembly.

Design Aspect Recommended Spacing
PCB to PCB 2-3 mm
PCB to Panel Edge 3-5 mm
Tooling Holes 3-5 mm from panel edge

Fiducial Marks and Tooling Holes

Fiducial marks and tooling holes are essential for accurate positioning and alignment during fabrication and assembly.

  • Fiducial marks: Used for vision systems to align the PCBs during assembly
  • Tooling holes: Used for securing the panel during fabrication and assembly
