2. H series, clearer stainless steel black marking effect, and larger marking area.
Application scenarios: marking patterns, QR codes, scales on tableware, kitchenware, utensils, etc. made of stainless steel
Stainless steel laser black marking has become a recognized ideal processing scheme in the marking field because of its permanent and clear marking, beautiful appearance, and high efficiency and environmental protection. It has gradually replaced silk screen printing, ink printing, stamping, and electric corrosion.

3.50W high frequency (170kHz), marking the shape of fish scales on the middle plate of the mobile phone can improve the efficiency of conductive position.
Application Scenario: Marking the conductive position of the middle frame of the mobile phone
The conductive position is the surface insulation of the metal frame of the mobile phone after oxidation treatment. According to the position of the signal transmission requirement, the laser strips the oxide layer at the corresponding position. The position where the oxide layer is stripped is the conductive position, installed different components on it which can realize circuit intercommunication.

4.50H high single pulse energy (1.5mJ), inductance coil stripping is more efficient.
Application scenario: circuit
The inductance coil is a common electronic component in the circuit, which can play the role of filtering and oscillation. When there is no current passing, it has a blocking function; when there is a current, it can keep the current constant. Because the smaller the gap of turn pitch, the more consistent the direction of the magnetic field lines generated by each turn, the stronger the magnetism, and the stripping can ensure that the gap is minimized.
