Cost Efficiency

This is one of the main benefits of having a PCB panel. If you want to make multiple PCBs, the manufacturer would likely charge more for the additional time they spend to manufacture a higher number of boards.

A panel will have multiples of the same design on a single PCB. This could result in one large board with over 30 designs and has to be made and processed only once instead of making it 30 times on multiple PCBs.

Faster Turnaround Time

Since many boards can make on a single panel in a single run, this results in a large amount of time-saving for the manufacturer. Which then results in faster delivery time for your PCB? You are using panel results in a faster time to market for your product.

Convenience Factor

Imagine you are working on a device that has one main board and two daughter boards. In a case like this, where your final product has multiple PCBs, It makes more sense to combine all three on a single panel. This also helps in organizing large quantities. Using a panel, you can make sure that all PCBs for a single product are on one panel rather than multiple PCBs scattered all around.

Faster Board Assembly

When doing board assembly, whether it be a couple of 10s of prototypes or 1000s, time consumed in swapping outboards and putting new boards into your machines causes a loss of productivity.

If you are doing it manually, then it takes a lot of time to align a stencil and then apply the paste to all boards. In situations like these, panels speed up the process. Loading a single panel of multiple boards results in faster production.

How to panelize PCB(Tips of panelizing PCB)

V Score or V Groove

Each panel after fabrication, we require a reliable method to separate from each plate. This method should be such that it requires minimal or no tools to separate boards. One such way to do it is by using V Score lines.

V Score lines are the cut line defined on the mechanical layer of the board design. The manufacturer then performs V-shaped cuts on those lines, which go about 1/3rd the board’s depth. The next step after this is to physically break off the boards, and they then break off cleanly along the edge where V cut lines exist.

Break Off Tabs

The second approach to separating individual boards from a panel is using break-off tabs. These are narrowed down areas of the board with many holes or vias drilled into the edge, which is later broken off.

On the application of force, the narrow region with the holes breaks off as it is the weakest point on the panel. The only disadvantage of using this approach is that the board edges won’t come clean. It is different from when using the V Groove method.


Whenever designing a panel, there needs to be a minimum clearance between individual boards on the panel. A board that uses V Grooves would also need some minimum clearance near the cut lines.

This value is usually about 2mm and is usually specified on the manufacturer’s technical capabilities page. A board that does not have enough clearance may break off in a manner that damages the board’s functional section.
