Laser technology is one of the four major inventions of the 20th century, alongside atomic energy, semiconductors, and computers. Over the past 50 years, laser technology has developed rapidly and has been widely applied in various fields, including industrial production, communication, information processing, healthcare, cultural education, and scientific research. As electronic products have evolved towards multifunctionality, portability, and miniaturization, the demands on electronic circuit fabrication have increased.

Laser Processing Goes Mainstream in the Electronics Industry

Laser Processing in the Electronics Industry - 1

Laser processing utilizes the energy of light focused through lenses to achieve a high energy density at the focal point, allowing for processing through photothermal effects. Laser processing requires no tools, offers high processing speed, minimal surface deformation, and can process a variety of materials. It is a non-contact method, making it ideal for the electronics industry as it avoids mechanical pressure or stress, meeting its processing requirements. Laser processing is widely applied in the electronics industry due to its efficiency, lack of pollution, high precision, and minimal heat-affected zone.

Advantages of Laser Processing in the Electronics Industry

Laser Processing in the Electronics Industry - 2
  • Laser processing achieves fine precision and enables micrometer-level processing, particularly advantageous in the creation of micro-holes and custom shapes in electronic circuit boards.

  • Laser processing offers high precision with laser beam spot diameters reaching below 1 μm, making it suitable for ultra-fine processing. It's a non-contact process with no significant mechanical force, ensuring high processing precision.

  • Laser processing covers a wide range of materials, suitable for processing various metals and non-metallic materials.

  • Laser processing has excellent performance and does not require special conditions for processing environments or working conditions, such as vacuum environments, radiation, or pollution.

  • Laser processing is fast, efficient, and straightforward.

Applications of Laser Equipment in the Electronics Industry

Laser technology encompasses multiple disciplines, including optics, mechanics, electronics, materials, and detection. Its research scope can be categorized into laser processing systems, which include lasers, optical systems, processing machines, control systems, and inspection systems, and laser processing techniques, such as cutting, welding, surface treatment, perforating, marking, and fine adjustment. Laser processing equipment primarily includes laser cutting machines, laser welding machines, and laser marking machines.

  • Laser Welding Technology in the Electronics Industry

    With the demand for smarter electronic products, circuit boards have become smaller, thinner, with more layers and electronic components. Laser welding has seen increasing use in the circuit board industry, especially in microelectronics. Laser welding has a small heat-affected zone, rapid heat concentration, and low thermal stress, making it uniquely advantageous in the packaging of integrated circuits and semiconductor devices. Laser welding is also used in the development of vacuum devices, such as molybdenum-focused electrodes, stainless steel support rings, and fast-heating cathode filament assemblies.

  • Laser Cutting Technology in the Electronics Industry

    Ultraviolet laser cutting has demonstrated significant technological advantages in the separation of circuit boards in the SMT industry and micro-drilling in the PCB industry. Depending on the thickness of the circuit board material, the laser cuts the required contours once or multiple times. Thinner materials allow for faster cutting. Laser cutting provides higher processing quality and efficiency for similar circuit board materials, reducing production costs and expanding the range of product design and processing.

  • Laser Marking Technology in the Electronics Industry

    Laser marking technology is one of the most prominent applications of laser processing. Depending on the material characteristics of circuit boards or electronic products, laser marking has extensive applications in the electronics industry. Laser marking involves using high-energy density lasers to locally irradiate the workpiece, causing the surface material to vaporize or undergo a chemical reaction resulting in a permanent mark. Laser marking offers high precision, fast speed, clear marking, and long-lasting effects. In the circuit board production process, it enables better information tracing and can be flexibly applied to various textual information, including complex product logos, QR codes, and more, addressing practical application problems that traditional methods struggle to achieve efficiently.

  • Laser Technology for Solder Mask Removal

    When producing solder masks, issues such as through-hole blockage or misalignment leading to solder pad coverage can occur. Laser technology offers a solution to both problems. By using lasers to penetrate holes blocked by solder mask and then removing the remaining material with a solvent, this process is fast and does not damage the board. Laser technology can quickly and accurately remove solder mask layers from circuit boards.

  • Laser Technology for Circuit Board Drilling

    Laser drilling machines are used for blind hole drilling in HDI and IC carrier boards, and they are the most widely used lasers in the PCB industry, with nearly 20 years of history. As electronic products continue to evolve toward lightweight, thin, short, and small dimensions, the use of HDI technology in circuit boards is increasing. Laser drilling is also applied to flexible boards. As the diameter of through-holes on flexible boards becomes smaller, with production of 0.1 mm diameter holes already underway and further development toward 0.08 mm and 0.05 mm, mechanical drilling costs rise, while laser drilling costs decrease, offering good hole shape and electroplating effects.
