Professional PCB Laser Marking Solution For Electronic Manufacturers
Printed Circuit Board (PCB) is the core component of almost all modern electronic products.From smartphones, automotive electronic systems, industrial controllers, medical devices and consumer electronics, PCB manufacturers require reliable identification technology to manage production information and product traceability.
During PCB production, manufacturers need to mark different information, including:
- Product model number
- Serial number
- Production batch information
- QR code
- Data Matrix code
- Manufacturer logo
Traditional printing methods may face problems such as poor durability, ink contamination, high consumable costs and limited traceability.
Laser marking provides a cleaner, more reliable and permanent solution.By using focused laser energy, the system can create high-resolution marks directly on PCB surfaces without physical contact.
JQ Laser develops customized PCB Laser Marking Machines for global electronics manufacturers, helping customers improve production efficiency, quality control and digital traceability.
