Semiconductor Lead Frame
Product Description
Product Detail
Lead frames,or Semiconductor Lead Frames are the metal structures inside a chip package that carry signals from the die to the outside, it is only a thin layer of metal frame that semiconductors are attached during the package assembly process, normally high density of leads is made by etching, and low density of leads are made by stamping.
