Two main cost factors in manufacturing leadframes are unit area and through-put. Unit area translates directly to copper usage. Through-put has direct impact on total overhead cost. Matrix leadframes have lower cost than single or dual-strand leadframes because they have smaller unit area and higher through-put.
Dynacraft has a wide variety of matrix SO leadframes as well as traditional single/dual-strand designs to fit existing mold tooling. All parts can be supplied with standard silver spot plating, ring plating.
