Ultraviolet laser light source for PCB QR code laser coding equipment is more refined 355nm UV laser is often used for FPC two-dimensional code laser marking Ultraviolet laser has the characteristics of fast speed and high power stability   The 355nm UV laser developed and produced by RFH is often used for FPC 2D code laser marking. The marking line width is narrow, the 2D code is fine, and the rating of the 2D code can reach A+. Mass production is in A or A-, marking the 2D code. With high reliability and quality, it is often used in PCB QR code laser coding equipment with high matching requirements.
