Laquer ablation

Efficient Removal of Colors and Laquers

When components must be selectively delivered from colors or lacquers for repair works or subsequent processes such as welding, brazing, bonding or forming, the laser ablations provides with high performances a contact-free, surface protecting method.

The layers that need to be removed evaporate in the process with particular pulses of the laser in q-switch operation and are disposed by considerate extraction systems.

Cleaning Process-Related Scaling from Components

Q-switched lasers with high performance allow the wear-free and selective cleanse of forms and tools from process residues such as soot, silicone, rubber, vulcanizing residues or oils and fat. This treatment is often necessary to prepare the surfaces for subsequent production steps like painting or welding. Due to the contact-free working laser there is not mechanical, chemical or impermissible thermal load carriage material

LED Manufacturing

Reliable High-Speed Marking

LEDs are expected to develop to one of the predominant light sources over the coming decades. They are already used for backlighting of flat panel televisions, mobile phones and the interior lighting of modern cars. Laser marking is an essential step in manufacturing the required LEDs.

One of ROFIN's strengths is the real-time compensation of position tolerances which is indispendable for a reliable production process. Moreover our laser markers provide cost-efficient operation and high integration capability.

Various Markings Through Different Marking Methods

When applying the color change method, the energy of the laser beam changes the optical properties of existing pigments. The surface remains virtually unchanged. As the material is changed down to a depth of 200 µm, the marking is remarkably durable and abrasion-proof. Adding of laser-sensitive pigments can improve contour sharpness and contrast of the markings.

Foaming, a partial degradation creating gas-bubbles within certain polymers, scatters the light and produces light marks.

CO2 lasers achieve similar marking results like hot stamping which only becomes visible by the shadow of the engraving. An effect which is desired for certain applications like marking of audio and data compact discs.
