✓ Why laser for PCB depaneling?
People often wonder why lasers are chosen for PCB depaneling instead of sticking to the conventional methods of milling and sawing.
The answer is simple if you know why you need a laser depaneling machine, our Info section will enhance your knowledge about lasers and their usage compared to conventional methods.
But to sum up, not all PCBs can be cut by milling and sawing tools due to mechanical and thermal stresses as well as the size of the PCB. Lasers can be employed in applications where small features are required
e.g. narrow cuts and places a milling tool do not fit into, cuts performed near sensitive electrical components, etc. Learn more here on speedLAS.com
✓ Can a laser process all materials?
It's a simple No! Just like a milling bit cannot mill all materials a laser cannot cut all materials. Even though a laser beam of specific wavelength can interact with many materials, it does not simply mean it can efficiently process them.
In most cases a group of material choices are matched with a certain laser wavelength for best material absorption, laser peak power, laser average power and financial aspects.
A well fitted Laser and material choice can overpower a conventional mechanical processing method.
✓ Throughput? Will it be faster?
For certain materials yes! Much Faster! For example the speed of metal cutting of metal sheets in the millimeter range, e.g. 1.0 mm can be superior to milling.
This however not always the case, where extreme precision and cleanliness is needed slower speeds might be needed.
✓ Combined motion of linear axes and laser scanner. What is the benefit?
The combined motion of fast linear axes and hyper fast laser scanners enables the programmability of complex trajectories.
One important feature is the motion On-The-Fly which maximizes the field of view of the laser scanner. Additionally it enables processing intricate
features on the PCB panel.
All that is being done while delivering competitive process speed, cleanliness and debree free processing. Not to mention that its a contact free process.
✓ Maintenance! Do i need it with lasers?
Lasers in general provide long life operation and significant reducion in maintenance costs.
There are no milling bits to exchange or saw blades to replace. The process is completely contact free!
With proper operating conditions your laser system would last years before its first service.
✓ When is speedLAS® More Cost-Effective?
- High-volume production where speed and automation offset initial costs (e.g., electronics, automotive).
- Intricate designs where mechanical methods are impractical (e.g., microelectronics, medical devices).
- Thin or fragile materials where contact-based methods cause damage.
- Multi-functionality where the same laser can cut, mark, and weld.
