Reflow Soldering
Reflow soldering is a common way to attach electronic parts to circuit boards in manufacturing. Think of it like baking - components are placed on boards with special paste, then heated in an oven until the paste melts and creates solid connections. This process is widely used for making electronic devices like phones, computers, and car electronics. It's more reliable and efficient than hand soldering, especially when dealing with tiny components. Companies often look for people who understand this process because it's crucial for making modern electronics.
