What is lead temperature?

Lead temperature refers to the temperature of the metal leads, which are used for connecting electronic components to printed circuit boards (PCBs). It is important to know the lead temperature because excessive heat can damage the components or the board itself. The maximum recommended lead temperature varies depending on the type of component and the manufacturing process. Typically, lead temperatures range from 150°C to 260°C, with maximum temperatures of 300°C or higher for some specialized components. Lead temperature is usually measured using a thermocouple or infrared temperature sensor. Proper monitoring and control of lead temperature are critical to ensure the reliability and performance of electronic devices.
