The analysis for trace level contamination is of critical importance in the manufacture of semi-conductors and printed circuit board testing. 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
