SEM
SEM stands for Scanning Electron Microscope, which is a specialized tool used to examine materials at extremely tiny scales. Think of it like a super-powerful microscope that helps quality control specialists and materials scientists see details that are impossible to spot with regular microscopes. It's commonly used in manufacturing, research labs, and quality testing facilities to check material quality, analyze failures, and ensure products meet specifications. When you see this term in a resume, it usually means the person has experience operating this equipment and interpreting its results.
