What inspires us
Why we developed Printoganth® U Plus
Your challenge
Reliable Cu-to-Cu interconnects, especially for high-end HDI applying anylayer designs, are crucial for the final product quality. Delamination on the capture pad or interconnect defects (ICDs) at the innerlayers are not acceptable for high yield manufacturing.
Our solution
Printoganth® U Plus is Atotech’s most reliable electroless copper process for horizontal application. Leading HDI manufacturers in Taiwan and China that are active in the field of consumer electronics are relying on Printoganth® U Plus since years because of its mass production proven, unparalleled reliability performance and excellent copper characteristics.
