Laser marking with YJ LINK
Laser marking with YJ LINK
Traceability concepts and customer requirements demand distinct traceability of PCBs for each step of the process. There are different methods to mark a PCB with a unique marking. Using labels and marking the PCB directly are the most well-known procedures. But while a label can fade or fall off, a marking that was directly brought into the PCB material ensures traceability over the entire lifespan of the PCB. With YJ LINKs new laser marking machine, that is designed for speed and performance, PCBs can be marked quickly and sustainably.
YJ LINK LASER MARKER
With the CO2 laser by YJ LINK, you can mark your printed circuit boards clearly, reliably, quickly and permanently: 1D and 2D codes as well as logos or characters are applied to the surface of a wide variety of materials using the latest laser technology.

Markings on PCB
-
Precise markings
- For PCBs with a size up to 610mm x 460mm
- Marking options: 1D Code, 2D Code and logos (image data)
- Traceability-Function and data backup via log file
- RGB LED illumination unit for best contrast for different PCB colors
- Clean marking due to high-quality Keyence laser
-
Double-sided marking
Thanks to the integrated high-speed turning-station, it takes only one process step to mark your PCBs on both sides.
-
Ghost Marking function
For a precise placement of the marking even on crowded PCBs, the code can be projected on the PCB prior to marking.
-
Saves space
Despite the integrated turning station and a large processable PCB format, the system has a small footprint due to its compact design.
-
Electrostatically discharged
The integrated surface ionization unit ensures a electrostatically discharged PCB after the laser process.
-
Automation and MES-connection
We realize the MES connection for you and provide the necessary automation - whether as an isolated solution or integrated into a production line.
-
100% clean
The powerful, two-stage extraction system with pre-filter and HEPA filter reliably extracts all particles generated and ensures a clean marking process.
-
Fully flexible
The code contents can be specified by a higher-level MES system or locally. The contents can be selected flexibly and can be constants (e.g. the serial number) or variables (e.g. the counter for the serial number).
IN TWO FAST STEPS
LASER DIRECT PART MARKING
Step 1
"Engraving" the code
A CO2-laser selectively ablates the PCB material. This causes a color change in the solder resist; the marking becomes visible.
Step 2
Cleaning the PCB
The material, that is evaporated during the laser process, is extracted immediately to prevent residues on the PCB.
FREQUENTLY ASKED QUESTIONS
The most commonly asked questions regarding laser marking
-
Do I need a laser safety officer to operate the laser system?
Since the YJ LINK laser marker is completely enclosed and equipped with additional safety measures such as a door interlock, the system has laser class 1.
A laser safety officer is therefore not required to operate the system.
-
What types of codes can be lasered?
Laser markers can usually laser all common types of codes as well as clear text. With the laser marker from YJ LINK, 2D codes such as QR codes and Data Matrix codes, 1D codes such as bar codes as well as plain texts, logos and images can be realized as marking on the PCB.
-
How small can the code be lasered?
A laser marker can be used to laser mark codes of almost any size. However, in order to be readable by standard scanners, a Data Matrix code should not be smaller than 2mm x 2mm.
-
How can the code contents be specified?
With the laser describer from YJ LINK, the code contents can be permanently defined in the system or dynamically specified as variables. Presetting the code contents via an interface is also possible.
-
Can the same counter be used on the top and bottom of the PCB?
Yes, with the YJ LINK laser marker, the same counter can be used on the top and bottom of the PCB.
