NCMS solvent substitution and material compatibility databases

The NCMS Solvent Database collects information on alternatives to ODC-based solvents used in electronics manufacturing. The database contains over 320 pure solvents and trade name mixtures. Each record includes 15 fields of environmental fate, 31 fields of health and safety, 21 fields of regulatory status, 36 fields of chemical/physical properties, and 19 fields of descriptive and supplier data. The Solvent Database is a stand-alone PC based application which runs under Paradox Runtime. The NCMS project, Compatibility Testing-Electronic Assembly Materials, examined the compatibility of seven ODC-free alternatives and two ODC-based control solvents on 124 materials commonly used in electronic assemblies. The materials groups included metals, metal surface coatings, polymers, composites, elastomers and shrink tubing, adhesives and locking compounds, non-metallic coatings, marking materials, and tapes. Pre- and post-exposure measurements included weight, volume, hardness, salt fog, dielectric strength, lap shear, torsion, adhesion, chemical/scrub resistance, pull strength, and dimensional stability. The solutions tested were: Freon TMS, 1,1,1-trichloroethane, isopropyl alcohol, Axarel 38, Bioact ECS, Bioact EC-7R, Ionox HC, RADS, and Vertrel 245
