Beam: The laser machine has two types of beams: red beam and white beam. The white beam is responsible for precise removal of the adhesive on the phone screen, while the red beam is used for positioning and assists in accurately aligning the laser beam for the dismantling screen.

Focusing: Before using the laser machine, it is necessary to perform focusing, which involves adjusting the lens focal length to form a uniform and appropriately sized spot on the positioning target plane.

Precision: Precision is crucial for screen split. Before making drawings, know the structure of the screen in detail. Where there is glue that needs a laser, where is the LCD screen and screen cable and where the beam needs to be avoided, all of them need to be measured in detail. And on the positioning mark, the mobile phone screen that needs to be disassembled should also be accurately placed in the area by the red light. If the drawing is not accurate enough and error, other parts of the phone may be damaged (such as the rear camera, cable), or some glue may not melt completely so that it difficult to remove the back glass.

It is important to properly set the parameters of the laser marking machine, such as frequency, power, speed, and others. If these parameters are not set correctly, no matter how many times the laser is applied, it will be difficult to remove the back glass of the phone.
