Leadframe Alloys

An exclusive line, consisting of a casting furnace, a tension leveller and a tension annealer, is installed at the Onsan plant

Technical innovation is possible in the high- technology industries only when the basic materials that support it provide excellent performance. With its high- level technology and rich experience in producing nonferrous metal products, Poongsan has developed new materials for semiconductor leadframes and connectors. It is asignificant contribution to the electronic and semiconductor parts industries. The new copper alloys, PMC102 and PMC102M, possess physical properties required for a semiconductor leadframe material, such as good electric and thermal conductivity, high thermal softening resistance and high metallurgical strength. Far better than the existing materials for plating and welding, they have beenregistered as CDA19010 and CDA19015, and patented in the US, Japan, and other advanced countries.



An exclusive line, consisting of a casting furnace, a tension leveller and a tension annealer, is installed at the Onsan plant to produce quality leadframe alloys that possess desirable physical and electric properties. They are separately under strict quality control. In addition to inventing a series of PMC102 alloys, Poongsan also supplies other kinds of copper alloys, such as C194 and PMC90, that possess the functions and characteristics required for a leadframe or connector part. The company has played a leading role in the semiconductor raw- material industry by developing PMC124, PMC91 and B alloys.
