About Laserssel

Based in Asan, South Korea, Laserssel is a publicly traded company specializing in area-selective laser soldering technology for the global semiconductor, automotive, and electronics industries. Founded in 2015, the company addresses complex manufacturing challenges, particularly those involving heat-sensitive materials and the potential for substrate warpage that conventional reflow processes cannot solve. The company's business model is centered on the sale of specialized laser-based soldering and rework equipment, serving a client base that includes top-tier semiconductor foundries and manufacturers of electric vehicles (EVs), mini/micro LED displays, and consumer electronics.

Laserssel's core technological offering is its Laser Selective Reflow (LSR) system, which leverages a patented Beam Shaping Optic Module (BSOM). Unlike traditional spot laser systems that concentrate heat in one point, the BSOM technology transforms a laser beam into a uniformly distributed "area beam." This allows for the precise application of heat to specific components in just a few seconds, without affecting thermally sensitive surrounding areas. This capability is critical for preventing warpage in very thin semiconductor packages, safely soldering components onto flexible PCBs for EV batteries, and reworking microscopic LEDs on display panels. The product lineup includes the Laser Compression Bonder (LCB) for high-end semiconductor packaging and the rLSR system for mini LED rework.

The company's history shows a consistent focus on R&D and market expansion. Shortly after its founding, Laserssel became a registered technology laboratory and secured government project participation. By 2017, it had established sales channels in Asia and began supplying major EV and semiconductor clients. The brand "Laserssel" was officially launched in 2018, the same year it secured Series B funding. Subsequent years saw expansion into the U.S. market, multiple technology awards, and a successful listing on the KOSDAQ exchange in 2022. The company reported trailing twelve-month revenue of $3.38 million as of March 31, 2025.
