PCB Panelization at Screaming Circuits

What is PCB Panelization?

PCB panelization is the process of grouping multiple printed circuit board (PCB) designs onto a single panel for manufacturing. This technique is commonly used to increase production efficiency, reduce costs, and simplify the assembly process. By placing several smaller PCBs on a larger panel, manufacturers can produce more boards in a single run, minimizing material waste and setup time.

PCB Panelization Techniques

There are several techniques used in PCB panelization, each with its own advantages and considerations.

Tab Routing

Tab routing involves connecting individual PCBs with thin tabs, which are later removed after the manufacturing process. This method is suitable for designs with irregular shapes or when a clean edge is required.

Advantages:
– Allows for irregular PCB shapes
– Provides a clean edge after depaneling

Disadvantages:
– Requires additional processing steps
– May leave residual tab material on the PCB edge

V-Scoring

V-scoring is a technique where V-shaped grooves are cut into the panel between individual PCBs. These grooves allow for easy separation of the boards after manufacturing.

Advantages:
– Easy separation of individual PCBs
– Minimal material waste
– Suitable for rectangular or square designs

Disadvantages:
– Limited to straight-line separation
– May cause stress on components near the V-score

Mouse Bites

Mouse bites are small, circular perforations placed between individual PCBs on a panel. These perforations allow for easy separation of the boards by applying pressure or using a tool.

Advantages:
– Easy separation of individual PCBs
– Suitable for irregular shapes
– Minimal material waste

Disadvantages:
– May leave rough edges on the PCB
– Requires additional processing steps

Designing for PCB Panelization

When designing PCBs for panelization, there are several factors to consider to ensure a successful manufacturing process.

Clearance and Spacing

Adequate clearance and spacing between individual PCBs on a panel are crucial to avoid interference during the manufacturing process. Designers should follow the manufacturer’s guidelines for minimum spacing requirements.

Fiducial Marks

Fiducial marks are reference points placed on the panel to ensure accurate alignment during the assembly process. These marks should be clearly visible and positioned according to the manufacturer’s specifications.

Tooling Holes

Tooling holes are used to secure the panel during the manufacturing process. The size, location, and quantity of tooling holes should be determined based on the panel size and the manufacturer’s requirements.

Panelization Layout

When arranging individual PCBs on a panel, designers should consider the following:

Orientation of the boards
Placement of components
Routing of traces
Efficiency of material usage

Assembly Considerations

PCB panelization also impacts the assembly process, and designers should keep the following considerations in mind:

Component Placement

Components should be placed on the individual PCBs in a way that allows for easy assembly and minimizes the risk of damage during the depaneling process.

Depaneling Method

The chosen depaneling method (e.g., tab routing, V-scoring, or mouse bites) should be compatible with the components and the overall PCB design.

Handling and Packaging

After depaneling, individual PCBs should be handled and packaged carefully to avoid damage during transportation and storage.

FAQs

Q: What is the minimum spacing required between individual PCBs on a panel?
A: The minimum spacing between individual PCBs depends on the specific manufacturer’s guidelines and the chosen panelization technique. It is essential to consult with your manufacturer to determine the appropriate spacing for your project.
Q: Can I use different panelization techniques on the same panel?
A: Yes, it is possible to use a combination of panelization techniques on a single panel, depending on the specific requirements of your PCB design. However, it is essential to ensure compatibility between the chosen techniques and to consider any potential impact on the manufacturing process.
Q: How does PCB panelization affect the cost of my project?
A: PCB panelization can help reduce the overall cost of your project by increasing production efficiency and minimizing material waste. By producing multiple PCBs on a single panel, manufacturers can reduce setup time and costs associated with individual runs. However, the specific cost impact will depend on factors such as the panel size, the number of PCBs per panel, and the chosen panelization technique.
Q: What are the most common pitfalls to avoid when designing PCBs for panelization?
A: Some common pitfalls to avoid when designing PCBs for panelization include:
Insufficient clearance and spacing between individual PCBs
Improper placement of components near the edges of the PCB
Inadequate consideration of the depaneling method and its impact on the PCB design
Failure to include necessary fiducial marks and tooling holes
Inefficient layout of PCBs on the panel, leading to material waste
