Laser Solutions for Electronic Components

& Modules

EV electronic components

In addition to batteries, vehicle electrification requires additional electrical components such as inverters, control boxes, and power distribution units (PDUs) to handle the flow of electrical signals and currents to the drivetrain components. Fiber lasers enable the welding of the inter-component connectors and busbars to meet critically important electrical performance requirements while also offering unmatched production speed, reliability, and ease of automation.

Laser Welding Provides Unique Benefits for EV Manufacturers

High-Quality, Low Resistance Connections

Laser welding easily overcomes the common challenges of welding copper, aluminum, nickel-coated steels, and steel alloys to create high-quality joints that optimize electrical properties with minimal heat input.


High Yield & Throughput

Laser welding is faster than other welding methods and is easily integrated with automation like real-time weld quality assurance that measures critical weld parameters without increasing cycle times.


Tooling Flexibility

Laser welding only requires single-side access, greatly reducing manufacturing complexity and tooling requirements when welding electric components like inverters and PDUs.

Five Key Laser Welding Advantages for Electronic Components & Modules

E-Mobility Lithium-ion battery thin metal cutting with a Laser
1. Dissimilar Material Welding Made Easy

Single-Mode lasers use high power density to easily join dissimilar materials frequently used in contact-to-busbar connections with minimal heat input to protect any nearby heat-sensitive components.

2. Spatter and Porosity Virtually Eliminated

Weld spatter and porosity, which increase the risk of short circuits in electronic components, are virtually eliminated by dual-beam technology that minimizes weld defects without reducing welding speed.

3. Increased Part Yield from Extended Process Window

Adjustable Mode Beam (AMB) dual-beam technology is more configurable than alternative dual-beam technologies, enabling an increased process window that ensures the creation of high-quality contact-to-busbar joints across a wider range of electronic component part variances.

4. High-Speed, Cost-Effective Welding

Air-cooled Quasi-Continuous Wave (QCW) lasers use bursts of high peak power to rapidly achieve the required weld depth in thicker busbars at lower average powers, reducing overhead costs without sacrificing welding speed.

5. 100% Quality Assurance with Real-Time Weld Measurements

IPG real-time weld quality assurance technology provides in-process contact-to-busbar weld data that enables the consistent creation of low resistance joints by guarding against process drift.
