    This paper provides a comprehensive overview of the development of flux-driven Josephson Parametric Amplifiers (JPAs) as Quantum Noise Limited Amplifier for axion search experiments conducted at the Center for Axion and Precision Physics Research (CAPP) of the Institute for Basic Science. It focuses on the characterization, and optimization of JPAs, which are crucial for achieving the highest sensitivity in axion particle detection. We discuss various characterization techniques, methods for improving bandwidth, and the attainment of ultralow noise temperatures. JPAs have emerged as indispensable tools in CAPP's axion search endeavors, playing a significant role in advancing our understanding of fundamental physics and unraveling the mysteries of the universe.
