PCB UV LASER MARKING MACHINE

UV laser PCB marking machines are standard equipment in high-end electronics manufacturing, and their core advantage lies in “cold processing” technology.

They use a 355nm short-wavelength laser to form marks by directly breaking the chemical bonds on the material surface, rather than relying on heat ablation, thus producing almost no heat-affected zone.

PCB UV LASER MARKING MACHINE ADVANTAGES：

Ultra-fine marking: The short wavelength of ultraviolet light and the extremely small focused spot (typically only about 20 micrometers in diameter) enable the marking of micrometer-level QR codes, barcodes, and logos, meeting the trend of component miniaturization.
Prevention of damage to precision circuits: The cold-processing characteristics ensure that the PCB substrate (such as FR4) will not be scorched, deformed, or delaminated during the marking process, making it particularly suitable for heat-sensitive FPC flexible circuit boards.
High contrast and permanence: It can produce clear, high-contrast color changes on various solder mask layers such as green, white, and black solder mask, and the marking is corrosion-resistant and heat-resistant.
Multi-material compatibility: In addition to standard PCBs, it is also widely applicable to marking IC chips, ceramic substrates, glass, and various engineering plastics.

PCB UV LASER MARKING MACHINE APPLICATIONS:

Micro QR Code: Marking on a piece of board the size of a fingernailOr even smaller QR codes to store information such as production date, batch number, and component origin.
Solder Mask Color-Changing Marking: Forming high-contrast black or white text on the surface of solder mask layers of different colors such as green, blue, white, and black. No ink is required, and it is resistant to strong solvent cleaning.
Multilayer Board Edge Marking: Marking serial numbers in narrow seams along the edges of PCBs for easy reading when stacked.
