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.
