Lead Frames

With the addition of various mechanical connections that formulate a more rigid structure, lead frames can be handled with ease. For the manufacturing process of lead frames, materials may be removed from a flat plate of copper, copper-alloy, or a type of iron-nickel alloy. To carry out such a process, etching or stamping may be used.
