Laser etching QR code, there is a special laser etching device, which is mainly used to etch all kinds of conductive films, conductive glass and so on. Its principle is similar to laser marking, but its accuracy is higher.

UV laser engraving machine refers to a kind of flying light path equipment with CO2 light source in the laser industry, which is mainly used for cutting and engraving leather, acrylic, fillers, wood and other products. Generally speaking, in the PCB industry, many customers will be called PCB laser engraving machine, which is commonly referred to as cutting, while laser engraving PCB QR code refers to marking.

So how is it generally defined in our laser industry? We will usually be more subdivided, for example, according to the light source, we will call it fiber laser marking machine, CO2 laser marking machine, ultraviolet laser marking machine and so on, and we will also divide them according to materials, such as PCB QR code laser marking machine and so on. As customers, they can generally be collectively referred to as QR code laser marking machine, QR code laser coding machine, etc.
