Laser Marking on Electronic Components

nct2

PCB Circuit Board

Fiber laser marking machines use a high-energy laser beam precisely focused on the PCB surface. The heat effect vaporizes or ablates metal or coating layers, engraving fine patterns, text, or removing excess coatings with high precision, making it ideal for intricate circuits and small-area markings.

As a non-contact process, laser marking eliminates mechanical wear, preserving the PCB surface. Additionally, it requires no chemical etching solutions, ensuring an environmentally friendly and efficient manufacturing process.

SD Memory Card

Fiber laser marking machines focus high-energy laser beams on the SD card surface, triggering color changes (such as oxidation or thermal decomposition) or surface texture modifications through heat effects, making the markings visible.

This process ensures high marking precision and durability, preventing wear or removal, making it ideal for long-term use and high-reliability storage device identification.

Computer Memory Module (RAM)

CO₂ laser marking machines use a 10.6μm infrared laser beam to create markings on memory module surfaces. When focused on the PCB, the high-energy heat effect locally heats, oxidizes, or decomposes materials, resulting in a color change that forms a permanent mark.

As a non-contact process, laser marking does not affect the electrical performance or data storage capabilities of the memory module. The concentrated heat remains on the surface, ensuring no impact on internal chips or circuits, maintaining product integrity and reliability.

Packaged Chip

UV laser marking machines apply markings to epoxy resin-encapsulated chips using a cold light source, enabling high-precision marking with minimal heat impact. This prevents thermal damage to the chip and surrounding structures, ensuring a safe marking process and material integrity.

With high-energy concentration, UV lasers precisely remove the epoxy resin surface, creating sharp and durable markings. This significantly enhances chip traceability while maintaining packaging stability and product quality.

Terminal Blocks

PA (Polyamide, commonly nylon) is widely used in electronic, automotive, and industrial terminal blocks due to its excellent wear resistance, chemical resistance, high mechanical strength, and electrical insulation properties.

Fiber laser marking typically utilizes short-wavelength, high-energy-density laser beams (e.g., 1064nm). When focused on the PA surface, the concentrated energy triggers a thermal reaction, causing carbon elements in the material to oxidize and form a black carbonized layer. This process decomposes organic components, removes moisture and volatiles, and leaves behind a carbon-rich dark mark, ensuring high contrast and readability against the PA material.

Terminal-Type Optocoupler

UV laser marking creates permanent and highly visible marks on optocoupler housings through carbonization and thermal decomposition. This process ensures high precision, strong contrast, and excellent durability. UV laser marking is widely used for permanent identification, serial numbers, or company logos on terminal-type optocoupler housings, particularly in industrial and electronic applications, ensuring long-lasting clarity and stability.
