👉 In the context of electronics, "precool" refers to a method or process used in manufacturing and assembly to reduce the temperature difference between two parts that are being joined together. This is particularly useful when working with materials that have low thermal conductivity, such as plastics or metals. By decreasing the temperature difference between the two parts, it helps prevent damage during the assembly process. In electronics, this might involve using a precooling tool to place one part of a circuit board into contact with the other
