Enthone has licensed an immersion tin patent to Atotech Deutschland GmbH that enables metals, such as silver, to be incorporated into the tin process solution.

The technology is used in the pre-dip process to induce large-grain tin deposits and reduce the rate of IMC formation, making the immersion tin deposit whisker- resistant, the company says.
