To enhance the efficiency of PCB manufacturing and assembly, we highly recommend utilizing panel designs. Panelization not only streamlines the production process but also helps reduce assembly costs.

The minimum panel size for assembly is 50x50mm, while the maximum can go up to 330x530mm. You have the option to provide your own panel design, or we can create one for you based on your specific requirements. When submitting a new order on PCBWay, simply include your panel design preferences in the message section.

Panel with V-Cut/V-Scoring/V-Groove

For V-scoring panelization, the spacing between boards can be either 0mm or 3mm. Below are reference images for your guidance:

By opting for panelization, you can significantly improve production efficiency and cost-effectiveness. Let us know your panel design needs, and we’ll ensure your PCBs are manufactured and assembled to the highest standards.

V-scoring has to be continuous and can not be stopped in panel, if you have many different boards like following image to be panelized, we suggest add tab routes between boards instead of V-scoring.

Panel with Tab Routing

For panels utilizing tab routing, a 1.6mm spacing is required between boards. There are two types of tab routing commonly used in panelization:

1. Tab routing with breaking holes (stamp holes)
2. Tab routing with tabs (no holes)

1. Tab Routing with Breaking Holes (Stamp Holes)

• The diameter of the breaking holes should be ≥0.45mm, with a typical range of 0.55mm-0.6mm.
• The spacing between holes must be ≥0.35mm.
• Typically, 5-6 holes are added to each tab for optimal strength and ease of separation.
• Refer to the following image for a visual example:

2. Tab Routing with Tabs (No Holes)

• The width of each tab must be at least 2mm.
• Refer to the following image for a visual example:

Panel with Both V-Scoring and Tab Routing

For panels combining V-scoring and tab routing:

• The spacing in the V-scoring area should be 3mm.
• The spacing in the tab routing area should be 1.6mm.
• Refer to the following image for a visual example:

Fiducial Marks and Mounting Holes in Panels

Fiducial Marks

• Fiducial marks are essential for assembly alignment.
• Typically, 3 fiducial marks are added to each panel.
• Each mark has a 1.0mm diameter with a 1.7mm soldermask opening.
• They are placed in the middle of the edge rails.
• Refer to the following image for more details:

Mounting Holes

• In addition to fiducial marks, mounting holes are also required for panel design.
• Typically, 4 mounting holes are added per panel.
• The diameter and location of the holes are shown in the following image:

Benefits of Panelization

Panelization offers several advantages for PCB production, including:

• Streamlined Production Process: Enhances manufacturing efficiency.
• Improved Yield and Quality Control: Reduces errors and improves consistency.
• Simplified Component Sourcing: Makes handling and assembly easier.
• Efficient Testing and Debugging: Facilitates faster and more accurate testing.
