Elephantech Announces Investment from Mitsubishi Electric and Strategic Partnership to Accelerate Global Deployment of SustainaCircuits
Tokyo, March 12, 2026 – Elephantech Inc. (Headquarters: Tokyo, Japan; CEO: Shinya Shimizu) today announced a strategic partnership with Mitsubishi Electric Corporation (TOKYO: 6503). As part of the agreement, Mitsubishi Electric will invest JPY 4 billion in Elephantech’s Series F financing. The partnership will accelerate the global adoption of SustainaCircuits, Elephantech’s proprietary sustainable printed circuit board (PCB) manufacturing solution, establishing it as an industry standard.
Great Synergy for Industry-Scale Deployment
Leveraging its strength in advanced nanomaterials and inkjet technologies, Elephantech has pioneered SustainaCircuits, a low environmental impact PCB manufacturing solution that significantly reduces copper consumption, process complexity, and production costs compared with conventional alternatives. The company is actively advancing industrial implementation of SustainaCircuits to drive broader market adoption.
In particular, the solution strategically targets general-purpose multilayer PCBs, which account for a substantial share of the approximately JPY 10 trillion global PCB market. In 2024, Elephantech successfully developed inkjet printing equipment and advanced materials (copper nanoink and primer) designed for this segment. Since then, the company has focused on validation and integration activities to introduce the technology into mass production lines at PCB manufacturers’ facilities.
Mitsubishi Electric brings extensive expertise in its Factory Automation Systems business, offering a comprehensive portfolio of products to PCB manufacturers. Recognized for high performance and reliability, the company has maintained a strong global presence across the PCB industry.
The partnership combines Elephantech’s technological advantages with Mitsubishi Electric’s capabilities in industrial equipment development, manufacturing excellence and global customer network. Together, the two companies aim to strengthen mass production capacity and expand sales of SustainaCircuits inkjet equipment now gaining traction among PCB manufacturers, further accelerating the widespread deployment of SustainaCircuits.

SustainaCircuits is Elephantech’s proprietary pure additive PCB manufacturing process that disrupts the heavily polluting DES approach. Through adopting SustainaCircuits, PCB manufacturers can produce low-carbon multilayer PCBs with significantly less copper consumption, water usage, and CO2 emissions. SustainaCircuits integrates Elephantech’s inkjet equipment, copper nanoparticle ink and optimized workflow. It replaces the core step in PCB fabrication while keeping subsequent steps unchanged, allowing minimal process disruption and seamless implementation.
