1-3 What is Electroforming (EF) technology?

It is a technology that combines semiconductor manufacturing techniques and electroplating to process high-precision fine holes.

- Using a semiconductor manufacturing technology called photolithography, resin pillars are formed on a stainless steel substrate. - Next, plating is performed, and after removing the resin pillars, peeling off the plated parts from the substrate results in a product with a large number of high-precision fine holes. <<Our production example>> Material: Nickel Approximately 160 million holes with a diameter of 5 μm are created in an area with a diameter of 20 centimeters.
