Capacitors are components that store electricity and electrical energy (potential energy). A conductor is surrounded by another conductor, or the electric field lines emitted by one conductor all terminate in another conductor, which is called a capacitor.

Capacitors are one of the commonly used electronic components in electronic equipment. They play an important role in circuits such as tuning, bypassing, coupling, filtering, blocking, energy conversion, and control circuits. Capacitance units are farad (F), microfarad (uF), picofarad (pF).

For capacitors, the logo is indispensable. Because different capacitors have certain differences in withstand voltage and rated voltage, if there is no mark, it is difficult to distinguish, which will cause a lot of trouble.

The naming of capacitor models in different countries is different, and there is no completely unified naming mode and standard. For domestic capacitors, its naming is composed of four parts (not applicable to pressure-sensitive, variable, and vacuum capacitors), which respectively represent the name, material, classification and serial number.

The first part: the name, expressed in letters, and C for capacitors.

The second part: materials, indicated by letters.

The third part: classification, generally represented by numbers, and individually represented by letters.

The fourth part: serial number, expressed by numbers.

Conventional capacitors will be marked with trademark, capacity, withstand voltage, error, model, certification trademark, etc. It is precisely because of these signs that people are more convenient to use and purchase. They can directly purchase according to the required rated voltage or model, avoiding a lot of trouble.

The capacitor is in direct contact with the current, so the identification information on its surface must be clear and long-lasting. The text information marked by traditional ink silk screen printing is not only unclear in font, but also easy to fade and fall off. Therefore, it is necessary to choose a marking equipment with clear and long-lasting markings—laser marking machine is the best choice.

Laser marking uses a laser beam to make permanent marks on the surface of various materials. The effect of marking is to expose deep material through the evaporation of surface material, thereby engraving exquisite patterns and text, and text information will never fall off and fade, so it is very suitable for marking on capacitors.

The editor of Foshan Fulan Laser will tell you what are the main characteristics of using laser marking machine for marking on capacitors:

1. The mark is permanent: the mark will not fade due to environmental factors (touch, acid and alkaline gas, high temperature, low temperature, etc.).

2. High precision: the laser marking machine is used for marking, with high marking accuracy, high definition and beautiful appearance. The UV laser marking machine produced by Fulan Laser adopts imported laser light source, with high beam quality and small focusing spot, which makes marking more precise and clear; the smallest line of 0.01mm can be printed on the surface of the material, and the smallest is The 0.06mm characters are especially suitable for small objects such as capacitors with large and extremely fine markings.

3. Non-contact processing, wide application range, low operating cost, high processing efficiency, fast editing and development speed, not only marking, marking any content and editing at will, environmental protection, high degree of automation, and ensuring the same product The processing effects of different batches are completely consistent and so on.
