PCB Depaneling – Wanting to Find Further Information on PCB Depaneling.

PCB (printed circuit board) depaneling, also referred to as singulation, is the process of removing numerous smaller, individual PCBs from a larger multi-PCB panel generated during manufacturing. The depaneling process was made to be able to increase throughout of PCB Router as circuit board sizes reduced. At CMS Laser, our depaneling process has the main benefit of speed, pin-point precision, no tooling charge or wear, no part induced stress, and no cutting oils or any other waste.

Need Motivated by Dimension

As modern technology consistently evolve, the devices we use become more sophisticated and quite often decrease in size. This lowered size needs more compact PCBs. Without set normal for PCBs, every single board is ideal for a specific product. Consequently, this process for depaneling separate boards from the multiple-appearance board is different. Creation elements such as tension, accuracy and sanitation are paramount to keeping table problems to a minimum.

Depaneling Strategies

PCBs are typically manufactured in big sections that contain several boards at the same time, but can be produced as single devices if necessary. The depaneling of PCBs method can be totally auto, handbook, or semi-automated. There are several methods employed, which includes laser beam PCB depaneling, within the electronics market. Let’s look at the things they are:

Punching/Pass away Slicing:

The punching approach is the procedure of singular PCB Depaneler being punched out from the solar panel by using a unique fixture. The punching fixture has well-defined cutting blades using one component and can handle on the other. Another pass away is needed for each board and dies should often get replaced to maintain sharpness. Although the production rate is substantial, the custom-created lighting fixtures and blades need a reoccurring price.


Panels are scored over the reduce collection on both ends to reduce all round table fullness. PCBs are eventually broken from the board. Both sides in the solar panel are scored to some depth of around 30 percentage from the board’s thickness. Once boards have been populated, they could be personally cracked from the solar panel. There exists a strain put on the panels that may harm a few of the elements or crack the solder joints, in particular those near the side of the table.

Tire Reducing/ Pizzas Cutter:

The “pizzas cutter” method is a handbook alternative to breaking the net right after V-scoring to reduce the other internet. Accuracy and reliability is essential, as the V-report and cutter wheels must be carefully in-line. There is a minor degree of tension aboard that could impact some parts.

Laser Depaneling

Laser beam depaneling can be executed on boards requiring higher tolerances. Depaneling happens without having actual physical make contact with, without any mechanical anxiety, and is also versatile to cut requirements via a computer controlled process. Laser depaneling is suitable for installation in area install modern technology (SMT) outlines or with table unloaders/loaders for standalone procedure.


Most PCBs are directed leaving behind the patient circuits connected to the solar panel frame by filter tabs which are eventually cracked or snapped to singulate the circuits. Routing may take up considerable panel area because of broad kerf width of the actual physical little bit.

Laser beam Routing:

Laser beam routing offers a full software-handled method with out reliance upon any mechanical dies or cutting blades. Laserlight routing can cut any form course including shape and well-defined sides. The cut kerf size may be under 20 microns, offering exceptional accuracy and reliability.

Laser beam routing can be executed utilizing both:

High-power CO2 laserlight (~10┬Ám wavelength)

The CO2 laser can thermally minimize through FR4, cup fibres as well as other rigid and flex circuit substrates at relatively high-speed though with noticeable temperature impact on the fringe of the reduce for many substrates.

Solid-state Ultra violet laser beam (355nm wavelength).

The Ultra violet laser, with a considerably more compact centered spot dimensions, ablates the panel material with significantly less warmth and a narrower kerf size. Nevertheless, as a result of lower strength amounts, the slicing pace is a lot more slowly than the CO2 laserlight and also the cost/watt of UV lasers is higher compared to Carbon dioxide

Generally, firms that are responsive to char and great particles over the cut series will employ the Ultra violet laser beam while users who thoroughly clean the circuits after singulation can benefit from the jgczun pace from the Carbon dioxide laser beam.

Ultimate Thoughts

Laser beam methods for depaneling play an important role in the future in the PCB producing market. As need for PCB Depaneling Router carry on and parallel technologies tendencies, like wearables and Web of Things (IoT) devices, the requirement for methods that boost manufacturing series pace and reduce charges for producer may also carry on and climb.

Within our Applications Improvement Laboratory, we work with each customer to ascertain the best laser beam and optics settings for any manufacturing process.
