Main Results and Discussion

High-resolution EPMA revealed submicron contaminant migration in solder joints. XPS imaging identified surface bond states beneath ultrathin films. AFM/SPM systems provided atomic-scale topography and mechanical property maps in air and liquid. Non-destructive CT enabled void detection and dimensional verification of plastic connectors and BGA joints. Infrared microscopy and FTIR quantified organic residues and film thickness. UV-VIS-NIR instruments measured antireflection coatings, while GC-MS and ion chromatography screened for VOCs, phthalates, halogens and sulfur. ICP-based techniques delivered precise quantification of heavy metals. Thermal analyzers characterized phase transitions in liquid crystal and epoxy materials. Mechanical testers quantified adhesion, shearing, compression and fatigue performance of components.
