The new QUALI-FILL® LIBRA online standalone metrology systems from ECI Technology have been specifically engineered to quantify material properties like Ni, Cu, SnAg and other crucial chemical species in plating solutions used for wafer packaging and other applications.
The QUALI-FILL® LIBRA system has a modular design and can be configured to fulfill users’ demands. Developed based on ECI’s established QUALI-FILL® chemical management platform, this sturdy system easily combines with R&D and production fabrications and is in compliance with the latest SECS/GEM and safety guidelines.
The QUALI-FILL® LIBRA K series takes metrology performance to an ultra-safe and ultra-clean wafer fabrication environment. It helps monitor plating chemicals used for wafer level packaging processes like TSV, RDL, UBM and Micro Bumping processes like fan-out, SOC, and others.
The QUALI-FILL® LIBRA A system has been developed for the tough settings of printed circuit board manufacturing. It is exclusively designed for analyzing plating chemicals in PLP and PCB manufacturing, like Electroplated Ni, Cu, Au, Pd, Sn and Sn-alloys, as well as Electroless Ni, Cu, Pd, Au and Zincate.
The smart QUALI-DOSE system combines easily with QUALI-FILL LIBRA systems to accurately dose plating baths with replenishing solutions.
