PCB laser marking machine

A circuit board marking machine is an automated device specifically designed to mark information on the surface of circuit boards (such as PCB printed circuit boards, FPC flexible circuit boards, etc.). Its main function is to leave permanent and clear marks on circuit boards through specific technologies, so as to meet the needs of production traceability, information identification, quality control and so on.

Laser marking machine
High-energy laser beams (such as fiber lasers and ultraviolet lasers) are focused on the surface of the circuit board, and the material surface (such as the solder mask and base material) is vaporized, discolored, or slightly melted by the instantaneous high temperature, forming a permanent mark.

■Advantages: Non-contact processing, no mechanical stress, no damage to circuits or components; extremely high precision (up to the micrometer level), suitable for high-density circuit boards; marks are wear-resistant, corrosion-resistant, and have a long service life; no consumables required, environmentally friendly, and suitable for mass automated production.

■Application scenarios: Most PCB/FPC, especially precision circuit boards (such as those in mobile phones, automotive electronics, and medical equipment).

Application value

The circuit board marking machine is a key auxiliary equipment in the electronics manufacturing industry, and the information marked by it can achieve:

■Full-life-cycle traceability: Quickly query production, quality inspection, and maintenance records by scanning codes.

■Anti-counterfeiting and brand management: Distinguishing genuine products from counterfeits through exclusive identifiers.

■Automated integration: It can be linked with the production line to realize the automatic entry of marking information and the docking with the traceability system.

The circuit board marking machine is an important equipment to ensure the production quality of circuit boards and realize refined management. Among them, laser marking technology has become the mainstream choice due to its high performance.

1. Excellent beam quality: The divergence angle is 1/4 of that of semiconductor pumped lasers. Especially suitable for precise and fine marking.

2. Low cost of use: The entire machine consumes less than 500W of electricity, which is 1/10 of that of a lamp pumped solid-state marking machine, greatly saving energy consumption expenses.

3. Maintenance free operation: The laser does not require any maintenance, nor does it need to adjust or clean the lenses.

4. Long service life of laser: Using laser diodes as pump sources, its average working time can reach 100000 hours.

5. Fast processing speed: The processing speed is more than three times that of traditional laser marking machines.
