IIoT and AI are changing electronics manufacturing by improving decision-making, reducing downtime, and speeding up production. Real-time data and predictive tools help optimize processes, improve product quality, and streamline supply chains. Examples like predictive maintenance, automated quality checks, and supply chain management show their practical benefits. While challenges such as data management, system integration, and skill gaps exist, the future is moving toward fully automated smart factories. In the long run, IIoT and AI bring cost savings, increased competitiveness, and better customer satisfaction.
