Predictive maintenance and preventative maintenance are similar, but not the same. Semiconductor Engineering said, "Predictive maintenance relies on the actual condition of the equipment in question, using real-time data coming from sensors to give operators visibility into the current state of the equipment. Preventive maintenance uses manufacturers’ maintenance schedules based on statistics of average or expected lifecycles for that equipment." While preventative maintenance is a guessing game, predictive maintenance will tell you what you need to know about the current state of your machines. If something is going wrong, you will know before your whole floor is stuck waiting on a repair.
It’s every production line manager’s nightmare—some machinery breaks down, stopping production on the factory floor. In a fab, if just one piece of semiconductor manufacturing equipment goes down and is out of service for hours, wafer fabrication can grind to a halt. Such shutdowns are expensive, especially if the plant is operating on a 24-hour schedule to meet demand. One selling point for the Industrial Internet of Things (IIoT) is it makes it possible to catch equipment failures before they happen by using predictive maintenance. What makes IIoT technology good for automating factory floors and simplifying data collection from smart meters and other products makes it good for keeping factory equipment running. Read More
