Our wet chemical analysis laboratory is fully staffed to continuously maintain and monitor the electroplating solutions being used in our production lines. In addition to traditional methods such as titrations, hull cell testing, and pH analysis, advanced analytical techniques include:
- High Performance Liquid Chromatography (HPLC) is used to separate, identify and quantify each organic component used in the plating solutions.
- Atomic Absorption Spectrophotometry (AAS) is used to measure metals within the plating solution.
- UV/Vis Spectroscopy is used to quantify metals, organic compounds and other elements.
- Total Organic Carbon Analysis is used to measure organic carbon and verify when operating solutions require treatment.
The analytical results from all testing generate a comprehensive data library. Through a customized software program, the library provides an essential resource in maintaining and optimizing process control for each chemical solution and operating line throughout the production floor.
Parameters for each chemical constituent of every electroplating solution are set up in the software. Some of these parameters include target values, upper and lower specification limits, as well as calculated addition quantities. The software generates a statistical analysis on any tested component based on analytical inputs. Range charts, moving range charts, histograms, run charts, CpKs, Cps, PpKs, and Pps are just some of the statistical tools.
