The QualiStream^® online analyzer enables tighter control of the wet surface treatment processes in the manufacturing of advanced PCB and IC Substrates. It automatically measures the components in the wet surface treatment tanks and communicates the data in closed-loop with the fab and/or the process tool for optimal replenishment and process control. Several concentration controls can be expanded by selecting various analytical methods depending on your plating solutions.

Control Etch Rates

• Automated sampling, analysis, and replenishment (optional) of solutions for:
  • Desmear (MnO4, NaOH)
  • Electroless copper plating solution analyzer (NaOH, HCHO, Cu)
  • Nickel electroplating solution (for watt bath) (Ni, Cl, pH, H3BO3)
  • Nickel electroplating solution (sulfamic acid bath) (Ni, Cl, pH, H3BO3)
  • Catalyst liquid (Pd)
  • Gold plating solution (pH, Au)
  • Conduction treatment liquid analyzer (Cu)
  • Developer/cleaning solution (NaOH)
  • Electroless Pd plating solution (Pd)
  • Processing liquid (Au)
  • Processing liquid (Au)
• This compact controller can perform many functions similar to ECI Technology’s full-size, higher grade QUALI-FILL^® LIBRÅ systems

Key Advantages

• Specifically designed for Advanced substrates, fast and very low cost per analysis – RF, SiP, AiP, Flip Chip (ABF Material), IC substrate, and PCB markets
• Process solution sampling via recirculation line or direct sampling
• ECI Technology is a leader with field-proven technology combined with easy integration into your production line
• Reduces chemical use, increases bath age and with supreme performance (accuracy and reproducibility)
• Contributes to technology advancements, cost reduction; less process solution, and lower labor costs for analysis and replenishment

Small Analyzer. Big Performance.

Metrology support for multiple chemistries and
process tools includes:

• Spectroscopy
• pH
• Titration
• Conductivity
• Density meter
• Surface tension

Automated analysis

Fixed-time elapsed analyses samples chemical solutions and analyzes the chemical solution concentration. Data is transmitted either by USB or external data communication network (optional). The data is calculated using ECI’s proprietary software and corrects the processing solution concentration to the preset value. The sensors and analytical cells are cleaned and readied for the next analysis to begin.
