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 maximize the efficiency and cost-effectiveness of PCB production by allowing multiple boards to be fabricated and assembled simultaneously.

Benefits of PCB Panelization

1. Cost reduction: By producing multiple boards on a single panel, the overall manufacturing cost per board is reduced.
2. Increased efficiency: Panelization streamlines the fabrication and assembly processes, reducing the time required to produce a large number of PCBs.
3. Improved handling: Panelized PCBs are easier to handle during the manufacturing process, as they can be processed as a single unit rather than individual boards.

Types of PCB Panelization

There are two main types of PCB panelization:

1. Tab routing: This method involves connecting individual PCBs with small tabs, which are later removed after the manufacturing process is complete.
2. V-scoring: In this technique, shallow grooves are cut between the individual PCBs, allowing them to be easily separated after fabrication and assembly.

Panelization Method	Advantages	Disadvantages
Tab Routing	– Strong panel connections – Suitable for large panels	– Additional process to remove tabs – Potential for damage during tab removal
V-Scoring	– Easy separation of boards – No additional tab removal process	– Less sturdy panel connections – Limited to smaller panel sizes

Designing for PCB Panelization

When designing PCBs for panelization, there are several factors to consider to ensure optimal results:

1. Board Spacing

Adequate spacing between individual boards on the panel is crucial to prevent damage during the fabrication and assembly processes. The minimum spacing required depends on the specific manufacturing capabilities of the PCB fabricator.

2. Panelization Method

Choose the appropriate panelization method (tab routing or v-scoring) based on your project’s requirements, such as panel size, board complexity, and the intended use of the final product.

3. Fiducial Markers

Include fiducial markers on the panel to assist with alignment during the manufacturing process. These markers help ensure accurate placement of components and improve the overall quality of the assembLED PCBs.

4. Panel Size

Consider the dimensions of the panel when designing your PCBs. The panel size should be compatible with the manufacturing equipment used by the PCB fabricator to avoid any issues during production.

Frequently Asked Questions (FAQ)

1. What is the minimum spacing required between boards on a panel?

The minimum spacing between boards on a panel varies depending on the specific manufacturing capabilities of the PCB fabricator. At Screaming Circuits, we recommend a minimum spacing of 2mm to ensure optimal results and prevent damage during the fabrication and assembly processes.

2. Can I use different panelization methods for the same project?

Yes, it is possible to use different panelization methods within the same project, depending on your specific requirements. For example, you may choose to use tab routing for larger boards and v-scoring for smaller boards on the same panel. Our team at Screaming Circuits can help you determine the best combination of panelization methods for your project.

3. How does PCB panelization affect the cost of my project?

PCB panelization can help reduce the overall cost of your project by allowing multiple boards to be fabricated and assembled simultaneously. However, the specific cost savings will depend on factors such as the size of your boards, the complexity of your design, and the total number of boards being produced. Our team at Screaming Circuits can provide you with a detailed cost analysis based on your project requirements.

4. What files do I need to provide for PCB panelization?

To begin the PCB panelization process, you will need to provide us with your PCB design files, typically in Gerber or ODB++ Format. Additionally, you should include any necessary assembly files, such as pick-and-place files and bill of materials (BOM). Our team will review your files and work with you to ensure all necessary information is provided before proceeding with panelization.

5. How long does the PCB panelization process take?

The time required for PCB panelization depends on various factors, such as the complexity of your design, the panelization method chosen, and the overall workload of our manufacturing facility. At Screaming Circuits, we strive to provide quick turnaround times without compromising on quality. Our team will provide you with an estimated lead time based on your specific project requirements.
