355nm UV Nanosecond Laser High Quality Marking Capacitors

When two conductors that are close to each other are sandwiched with an insulating medium, a capacitor is formed. Capacitor is an electronic device and an energy storage element. It is an indispensable and important element in electronic circuits. It has the function of passing AC and blocking DC. When a voltage is applied between the two plates of the capacitor, the capacitor will store charge. .

Capacitors are widely used in high frequency and low frequency circuits and power supply circuits, with functions such as coupling, filtering, bypassing, resonance, boosting, timing, etc. With the increasing demand for capacitors in the market, there are different types of capacitors produced by different manufacturers in the market. In order to facilitate product management, manufacturers mark data such as product brand, model and parameters on capacitors. These marking information must be accurate and clear to facilitate customers to identify applications.

So the question is, do you use ink for printing? It is too out. Now, laser marking equipment is introduced into the capacitor production line. The high-energy-density laser beam acts on the surface of the capacitor material, so that the surface material is quickly vaporized to expose the deep material. The marked text and pattern information are clear, not fading, and not. It is a permanent mark and is not easy to be tampered with. It can be a good substitute for traditional ink printing, and has strong anti-counterfeiting properties to a certain extent. It can even be accurate to the production date of the capacitor and the information of the production machine, so it is very suitable for printing in mark on the capacitor.

Moreover, the advantage of laser marking lies in non-contact processing. When marking the capacitor, no additional force is applied, and there is no need to worry about deformation due to force. Moreover, the marked graphic information is edited and output by computer software, and the content can be changed at will. More flexibility, simple and convenient operation.

The 355nm ultraviolet nanosecond laser has high beam quality (M2<1.2), narrow pulse width (about 25ns), stable output power of 5W, and the "cold" processing of 355nm ultraviolet light and the small spot diameter brought by easy focusing can meet the requirements of depth, line Width, smoothness, contrast and fineness have higher marking requirements.
