High density leadframe
Did you know?
Lead frames are manufactured by removing material from a flat plate of copper, copper-alloy, or iron-nickel alloy like alloy 42. Two processes used for this are etching (suitable for high density of leads), or stamping (suitable for low density of leads). The mechanical bending process can be applied after both techniques. The die is glued or soldered to the die pad inside the lead frame, and then bond wires are attac… WebFor low lead density and larger package assemblies the preferred process is stamping, which is usually employed in high volume production runs. The process of stamping is automated and runs at a very high speed, …
