Cleanliness Bath Analysis of Your Electronic Assemblies
Precise analyses and well-founded interpretations for reliable manufacturing processes and high-quality standards
cleanliness & Bath AnalysisWell-Founded Results, Reliable Interpretation
With our cleanliness and bath analyses, we provide you with well-founded results and reliable interpretations. We examine your entire cleaning process using various test methods – optical, chemical, and physical.
Our detailed technical reports, including image documentation, ensure maximum transparency and traceability. Additionally, we assess the potential impact of residual contamination and provide concrete recommendations for optimizing your processes.
cleanliness analysis from a single sourceWe Analyze with Micron-Level Precision
Contaminants such as flux residues or particles can significantly impact the functional reliability of electronic assemblies. Our cleanliness analyses detect these residues with the highest precision – down to the micron level.
But we offer more than just data: Using state-of-the-art analytical methods, we assess the surface cleanliness of your assemblies. Our experts interpret the results and develop targeted measures to resolve existing issues and sustainably optimize your production processes.
