LINK-US Co., Ltd. (LINK-US), a company committed to connecting people, has celebrated its 10th anniversary. With its unique "Ultrasonic Composite Vibration Bonding Technology," the company is accelerating its business growth and contributing to the realization of a carbon-neutral society. To further promote this cutting-edge technology, LINK-US has relocated its headquarters to a larger facility.

Background of Headquarters Relocation
Since its founding in 2014, LINK-US has been developing and manufacturing world-first ultrasonic composite vibration bonding equipment for joining dissimilar metals. This innovative bonding method has been rapidly adopted in the manufacturing of next-generation batteries and semiconductors.
Ultrasonic composite vibration bonding offers a highly efficient and low-damage joining process compared to conventional methods. It utilizes a unique patented technology that employs ultrasonic vibrations in circular or elliptical patterns.

Thanks to our dedicated research and development efforts, and the support of our customers, our technology has gained high recognition in the fields of automotive lithium-ion batteries (LiBs) and power semiconductors. Unlike conventional joining methods, our technology eliminates the formation of alloy layers and the inclusion of impurities. Furthermore, as ultrasonic vibrations create atomic bonds between materials, the process generates minimal heat and eliminates the need for cooling, resulting in a 90% reduction in carbon dioxide (CO2) emissions compared to conventional welding methods.
With this expansion, we will expand our laboratory facilities and increase our workforce to further accelerate the development and sales of ultrasonic composite vibration bonding equipment.

Concept of the New Office
・Creating a workplace environment that fosters new solutions
・Activating communication based on our corporate philosophy

Meeting room

The new office offers an open and inviting space for our visitors. We have installed multiple units of our equipment in the office, and our laboratory facilities allow visitors to observe demonstration tests of joining various dissimilar metals, such as aluminum and copper (upon request).
