Exquisite metal stamping parts IC lead frame / led lead frame / copper lead frame / integrated
circuit lead frame
Lead frames are the metal structures inside a chip package that carry signals from the die to the outside.
Leadframe for a QFP package
The die inside the package is typically glued to the lead frame, and then bond wires attach the die pads to the leads. In the last stage of the manufacturing process, the lead frame is moulded in a plastic case, and outside of the lead frame is cut-off, separating all leads.
Progressive die for lead frame:
-- Discrete device lead frame dies: TO-92,TO-196,ITO-220,TO-252,TO-247,TO-3P etc.
-- IC lead frame dies:DIP-8L,DIP-16L,DIP-18L,DIP-28L,SOP-8L,SOP-16L,SOP-28L,SSOP-8L,SSOP-18L etc.
-- SMT lead frame dies: SOT-23,SOT-143 etc.
