UV laser marking PCB circuit board, showing high technology

Since the reform and opening up, China has attracted a large-scale transfer of manufacturing in Europe and the United States due to its preferential policies in labor resources, markets, and investment. development of related industries.

As the "mother of electronic products", PCB circuit board is an important electronic component, the support of electronic components, the carrier of electrical connection of electronic components, and the upstream of almost all electronic consumer goods, whether it is mobile phones, computers, tablets, etc. Display screens, etc., will use circuit boards and have a wide range of applications.

There are two main types of PCB marking processing: silk screen printing and laser marking.

The traditional silk screen printing process is rough, and the logo is easy to fall off, causing inconvenience to the user. In addition, the silk screen processing procedure is cumbersome, and the operator needs to be replaced in time to ensure the production efficiency, which increases the labor cost.

With its accuracy and flexibility, laser marking can make up for the lack of silk screen processing, and gradually become the best processing tool for PCB marking, and will play a pivotal role in the circuit board industry!

Laser marking technology can skip number marks, realize one code for one item, and mark two-dimensional code on the PCB, which can achieve quality traceability and let users know product information with one click.

Marking

Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the PCB board to vaporize or change the color of the surface material, thereby leaving a permanent mark.

Laser marking can print various characters, symbols and patterns, etc., and the character size can range from millimeters to micrometers, which is of special significance to the anti-counterfeiting of products.

What is the special laser marking machine for PCB?

What about "sparkle"?

High precision: Laser marking is fine and precise and non-contact processing. It can mark thin lines below 0.1mm and characters and numbers within 0.5mm on the surface of the material, which is especially suitable for circuit boards that require extremely small graphics and text.

High quality: Electronic chips have higher requirements for marking quality, clarity and permanence. Laser marking machine can achieve permanent and clear marking of chips, and the marking will not fade due to external factors such as high and low temperature, acidity and alkalinity, and friction.

Safety and environmental protection: only a small amount of gas is generated and discharged through exhaust air, no chemical assistance is required, and the safety of operators and the working environment are protected as much as possible.
