Fiber lasers have made a massive impact in the electronics industry, which continues to soar due to the mass demand for electronic products. Fiber lasers are ideal for process automation and integration into manufacturing workflows.

Electronics industry applications and uses

E-mobility is booming, and electric vehicle manufacturers are using fiber lasers to ablate wire hairpins in electric motors prior to welding. This process ensures a better weld as the coating layer on the hairpin is stripped back seamlessly to the bare metal.

The laser marking application is used in areas such as marking electronic epoxy and integrated circuit marking, where QR codes are added for information purposes such as connections and orientations. Engraving and marking are used for the addition of serial numbers to electronic parts.

Laser cutting is used for the precise and contactless cutting of various electronic components such as USD cards and circuit boards.

Laser Additive manufacturing (3D printing) is ideal for the mass production of identical electronic parts. This application is increasing in popularity with a switch from traditional manufacturing techniques.

Laser welding is extensively used in creating seamless joins such as in printed circuit boards manufacture and also in many other types of electronic components.

The electronics industry and SPI Lasers

Fiber lasers will be used increasingly in the electronics industry as new breakthroughs in the technology allow for more and more traditional processes to be replaced.

SPI Lasers will be at the forefront of fiber laser technology offering a wide-variety of applications through our pulsed and continuous wave fiber lasers. The electronics industry will benefit from all 8 of our applications, but particularly marking, cutting, and 3D printing (additive manufacturing). Other laser applications include ablation, cleaning, welding, drilling and engraving. Contact SPI Lasers to see how our fiber lasers can help your organisation move forward in the field of electronics.

We have created a selection of electronics industry application insights and postcards to enrich your knowledge of the capabilities of fiber lasers within this industry.
