Wave soldering is a reliable method used in electronics manufacturing to attach electronic components to circuit boards. Think of it as an assembly line process where circuit boards "ride a wave" of melted metal (solder) that creates permanent connections. It's like a automated version of hand-soldering that can handle many components at once, making it faster and more consistent than doing it by hand. This process is commonly used in electronics repair shops, manufacturing facilities, and assembly plants where large numbers of circuit boards need to be produced or fixed.
