Marking accuracy:+/-0.01mm

The Inline Laser Marking Machine enables fast, direct, and contactless marking on PCBs — ideal for SMT production lines.

Equipped with a precision X/Y gantry, the laser system marks solder resist surfaces with barcodes, data matrix codes, serial numbers, or logos. The PCB is automatically conveyed to the marking area, where the laser executes high-speed marking at the pre-programmed coordinates — ensuring accuracy, traceability, and seamless integration with inline workflows.

Laser marking machines with two laser head

No matter the material — solder resist, metal, plastic, or ceramic — Vanstron offers the optimal laser solution for every application. Whether it’s CO₂, UV, or fiber laser, the system is adaptable to meet your production needs with precision and reliability.

For advanced traceability, Vanstron supports smooth integration with MES systems via standardized protocols or customized interfaces — ensuring real-time data flow and full process transparency across your smart factory.

Marking Quality

Vanstron’s inline marking system is equipped with a high-resolution camera that captures images both before and after marking. This enables automatic contrast comparison to detect missing, incomplete, or low-contrast markings — ensuring zero-defect quality control.

The integrated 2D code reader instantly decodes and verifies the marked content based on industry standards.

With intelligent graphic algorithms and robust database support, the system performs multi-level evaluation of QR code quality. It is precisely calibrated against Keyence scanners to ensure flawless accuracy in grading — making it a trusted solution for traceability-critical production environments.

Barcode quality verification by Keyence scanner

BEST Example – barcode on Green PCB

It has a bright pattern with dark background, so it has good contrast ratio and good scan rate. The marking quality is excellent because the size of the marking DOT and the margin are the same(equidistant interval).

Bad Contrast Example – barcode on Red PCB

Most scanners use red LEDs for lighting. At this time, the red PCB strongly reflects the red LED, so the brightness difference between the barcode and the PCB color is reduced, resulting in a lower scan rate. If you are marking on a red PCB, the reading rate can be improved by using white illumination. However the reading rate may drop if other colors are going to be used under the same illumination. Therefore, it is very important to check the colors of the boards that are going to be used at customer’s site in advance.

Marking stability accuracy

Exceptional marking accuracy starts with the right core components. That’s why Vanstron uses only premium galvanometers from leading German brands, ensuring the highest standards of laser beam stability and precision.

This commitment to quality guarantees sharp, consistent, and reliable marking results — even in demanding high-speed SMT production environments.

German-engineered galvanometer system
✓ Ultra-fast scanning response
✓ Long-term thermal stability
✓ Designed for 24/7 industrial marking
✓ Guaranteed alignment precision ≤ ±0.01mm

High-speed scanning & marking

A high-quality galvanometer is the important elements for a high-performance laser marker machine, when the galvanometer quickly and accurately change the propagation direction of the laser beam, which greatly improves the marking speed and meets the needs of efficient production.

In some electronic components requiring fine marking, the high precision of the galvanometer can ensure the accurate position and shape of the mark;

In large-scale production, the high-speed scanning of the galvanometer can quickly complete the marking of many products and improve production efficiency.

FAQ

Q Does the system support multi-color PCBs?

A Vanstron: Yes. It can reliably mark on green, black, red, white, blue, and even purple solder masks.
Q How is the marking position accuracy ensured?

A Vanstron: The system uses fiducial recognition and achieves a positioning CPK > 1.67 ( accuracy +/-0.01mm)
Q What materials can be marked using your laser?

A Vanstron: Solder resist, metals, plastics, and ceramics — depending on the laser source selected (CO₂, UV, or Fiber).
Q Can it support array or panelized PCB marking?

A Vanstron: Yes. Group/array marking is supported, with flexible programming templates.
Q Can the marking quality be verified automatically?
A Vanstron: Yes, our system supports automated marking quality verification .
We integrate a high-resolution vision inspection module into the laser marking system, which performs real-time verification of the marking quality after each operation. This module checks for parameters such as:
- Clarity and legibility of the 2D code or text
- Contrast level to ensure readability
- Position accuracy relative to the reference point
- Completeness of the marked content
