Paste Paste composition and its manufacturing method with a conductive thermally conductive corrosion-resistant properties

摘要

The present invention provides a paste composition having heat dissipation properties and anti-corrosion properties along with conductive properties similar to those of Ag paste and Cu paste for electrodes, and the like used in the manufacturing of electric/electronic parts; and a production method of the same. More specifically, due to miniaturization and slimming of electric/electronic parts (devices and products), resolving of heating due to locally generated heat has been one of the most important problems. Particularly, the conductive pastes for electrodes typically require high conductivity with a resistivity of 100 μΩ-cm or less, adhesive properties, hardness, palatability, and the like; and are often used as a material for components in power inductors and condensers. However, the conductive pastes currently used have a thermal conductivity of 0.5-1.5 W/m-K, and thus have low heat dissipation properties. Therefore, the present invention relates to a paste composition prepared to possess electric conductivity, heat dissipation properties, and anti-corrosion properties by adding metal powder having excellent heat dissipation property, conductive carbon, and low-melting point solder to a polymer material, and to development of a production method for the same.
