The traditional stencil printing process is to fix the shape of the stencil (to cover the required light-transmitting area), and then spray paint to obtain the light-transmitting effect of the image. However, the stencil needs to be cleaned or replaced regularly, and when a new light-transmitting image is needed, the stencil has to be made again, and the positioning accuracy is not high enough to meet the precise processing needs of modern electronic products.

The introduction of the laser ink removal process has solved all these process challenges.

Laser ink removal technology refers to the use of high-energy laser beam to irradiate the surface of the work-piece, so that the surface of the ink coating to evaporate and peel off instantly, and to achieve the process of ink removal.

Laser ink removal technology as a new environmentally friendly cleaning technology, mainly used in 3C industry and intelligent terminals.

• Selective processing, no damage to the substrate

Selective processing for the ink layer, light transmission rate of more than 90%, no damage to the substrate.

• Precise positioning, high processing precision

Adopt CCD vision positioning module, processing accuracy can be controlled within ±0.02mm.

• Strong processing capability, processing arbitrary graphics

Compatible with PHOTOSHOP, CORELDRAW, AUTOCAD and other drawing software, to achieve arbitrary graphics processing.

• Energy saving and environment-friendly

No need to add solvent, can use smoke dust removal device to purify the space, no pollution to the environment. Stable operation of the equipment, no consumables loss.
