The testing for trace level contamination is of critical importance in the manufacture of semi-conductors and printed circuit boards. A large range of chemicals from cleaners and developers, to PCB anti-foams and etching acids, all require testing to strict specifications.
Examples of work undertaken by us in this area include:
- High-purity water for Trace Anions and Cations
- PCB Extracts
- Anions in Encapsulation Plastics and Moulding Compounds
- High Purity Electronic and Semiconductor Grade Solvents
- Acids, Bases, Etching and Cleaning Solutions
- Trace Anions in Hydrofluoric and Phosphoric and other concentrated acids
- Trace Anions in Concentrated Alkaline solutions
- Plating Bath solutions
- Trace metals by ICP-OES
