PCB (printed circuit board) depaneling, also referred to as singulation, is the procedure of removing numerous smaller, individual PCBs from the larger multi-PCB panel generated during manufacturing. The depaneling process was created so that you can increase throughout of PCB Depaneling as circuit board sizes reduced. At CMS Laser, our depaneling process has the benefit of speed, pin-point precision, no tooling charge or wear, no part induced stress, without any cutting oils or any other waste.

Need Powered by Dimensions

As modern technology continues to evolve, the gadgets we use become more advanced and quite often decrease in dimension. This decreased size requires more compact PCBs. With no set up standard for PCBs, each and every board is designed for a specific product. Therefore, the process for depaneling independent panels coming from a multiple-picture board is different. Production factors including anxiety, accuracy and hygiene are vital to keeping board defects as low as possible.

Depaneling Methods

PCBs are typically created in big solar panels containing multiple boards at a time, but may also be made as solitary models if necessary. The depaneling of PCBs process could be completely automated, guide, or semi-auto. There are numerous methods utilized, such as laser beam PCB depaneling, inside the gadgets market. Let’s analyze whatever they are:

Punching/Pass away Slicing:

The punching method is the method of singular PCB Depanel being punched from the board by using an exclusive fixture. The punching fixture has well-defined blades on one component and can handle on the other. Another pass away is required for each table and dies must regularly get replaced to keep sharpness. Even though the creation rate is higher, the custom-designed fixtures and rotor blades need a reoccurring expense.


Boards are scored across the reduce series on sides to minimize all round board thickness. PCBs are consequently cracked out of the solar panel. Either side in the panel are scored to your degree of around 30 percent of the board’s density. As soon as panels have already been inhabited, they could be personally broken from the solar panel. There exists a tension place on the boards that may harm some of the components or break the solder bones, in particular those near to the fringe of the table.

Wheel Slicing/ Pizza Cutter:

The “pizza cutter” strategy is a handbook substitute for breaking the web after V-scoring to reduce the other website. Accuracy and reliability is essential, because the V-rating and cutter tires must be carefully in-line. There is a minor degree of stress aboard which may affect some elements.

Laser beam Depaneling

Laserlight depaneling can be carried out on boards requiring high tolerances. Depaneling takes place with out actual physical contact, without mechanised anxiety, and it is adaptable to cut specifications by way of a personal computer controlled method. Laser beam depaneling would work for installation in surface attach technology (SMT) facial lines or with table unloaders/loaders for stand alone procedure.


Most PCBs are routed leaving the person circuits linked to the panel framework by filter tabs which can be eventually cracked or snapped to singulate the circuits. Routing will take up substantial panel region as a result of broad kerf width of the actual little bit.

Laser Routing:

Laser beam routing offers a complete computer software-managed procedure without having reliance on any technical dies or cutting blades. Laserlight routing can reduce any shape path which includes curves and sharp sides. The minimize kerf width can be lower than 20 microns, supplying excellent accuracy.

Laser routing can be performed using possibly:

High-strength Carbon dioxide laser beam (~10┬Ám wavelength)

The Carbon dioxide laser can thermally cut through FR4, window fibres and other rigid and flex circuit substrates at fairly high-speed however with noticeable warmth impact on the side of the reduce for most substrates.

Strong-condition UV laser (355nm wavelength).

The UV laser, with a significantly smaller sized centered area dimension, ablates the solar panel material with considerably less heat along with a narrower kerf width. Nevertheless, because of lower strength levels, the cutting speed is a lot reduced compared to the Carbon dioxide laser and also the cost/watt of Ultra violet lasers is increased than that of Carbon dioxide

In general, firms that are sensitive to char and good particles along the cut collection will utilize the UV laser beam although users who clean the circuits following singulation may benefit from the jgczun pace of the CO2 laser.

Last Thoughts

Laser beam systems for depaneling play an integral part down the road of the PCB producing market. As demand for PCB Depaneling Router still parallel technology tendencies, including wearables and Internet of Points (IoT) gadgets, the necessity for methods that boost production line speed and reduce expenses for manufacturer may also carry on and rise.

Inside our Applications Improvement Lab, we work with each and every customer to determine the best laser and optics setup for a producing method.

In this particular a few-portion range on PCB depaneling, upcoming posts will talk about the advantages and difficulties of PCB depaneling, combined with the evolution of PCB depaneling with laserlight systems.
