Hoop soldering refers to a technique for continuously soldering strip-shaped metal material (hoop material), or the product processed by this technique. This process is essential for the electrical joining and surface treatment of mass-produced precision components such as lead frames for electronic components, connector terminals, and various sensor parts. By utilizing the continuous feeding of hoop material, highly efficient and precise production by automated machines is possible, contributing to cost reduction and quality stabilization. Typical processing methods include dip soldering, flow soldering, laser soldering, or reflow soldering after solder paste application. Particularly, to accommodate fine pitches and complex shapes, precise positioning and strict temperature profile management are required.
