Focus Area(s): Printed Circuit Boards (PCBs)

Summary: Elephantech has developed a revolutionary method for manufacturing printed circuit boards (PCBs) using metal inkjet printing and selective plating. Unlike traditional methods that etch away copper from large metal sheets, creating significant waste, our approach builds circuits additively, only where needed.

Here’s how it works: we first inkjet-print a special metal catalyst pattern directly onto a flexible film. Then, we use a chemical plating process to grow copper only on the printed areas, forming precise and functional circuits. This method eliminates the need for copper laminate boards and drastically reduces the use of chemicals, water, and energy.

Our technology reduces CO₂ emissions by up to 75% and liquid waste by up to 95% compared to conventional PCB manufacturing. It also enables simpler, more agile production in compact facilities, making local, sustainable electronics manufacturing a reality.
