Uniplate® PLBCu6

Inline process from desmear to flash plating for mSAP for high end HDI boards

Atotech’s horizontal equipment is the solution of choice for modified Semi-Additive Process (mSAP) technology. This wet-to-wet solution is designed to produce outstanding reliable interconnects at a very high throughput while minimizing handling and operating needs in the process from desmear and electroless copper to flash plating.

Atotech’s system incorporates innovations that allow significant savings of water and energy and at the same extend the life time of chemistry. Atotech’s system utilizes Securiganth® E series for desmear, Printoganth® U Plus for PTH and Inpulse® 2HFU for electrolytic copper plating to achieve superior throwing power and uniformity.

For finer line and space requirements our Uniplate platform provides several universal transport system solutions for lines and space down to 40μm + 2×2μm copper clad. In addition, we are able to offer solutions for the avoidance of particles and a sophisticated filtration package for fineline structures.
