R&D Field

Chang Sung Corporation’s soft magnetic metal powder cores are vital components for a variety of electronic products, including IT devices. With years of experience in manufacturing raw materials and component processing technology, we are now focusing on designing and developing magnetic materials and components with excellent performance at high frequencies and large currents for the next generation power systems with high functionality (EVs, PV/fuel cell systems, etc.)

CSC’s coil products are used as inductors and high frequency transformers, which are indispensable for eco-friendly electric vehicles and the power converters of solar inverters. We are developing inductors using inhouse developed soft magnetic powder cores and magnetic paste, as well as compact/high-efficiency inductors for eco-friendly cars and low-loss high-frequency inductors for PV systems.

In the low-temperature-curing paste field, continuous focus is placed on developing products with improved printability that can allow for a reduction in the line width of electrodes, highly-conductive products that can meet the demand for increasing the current density, and high-reliability products that result in less substrate deformation and a small variation in resistance according to the external environments.
The high-temperature-Sintering paste field retains its focus on developing paste products with high dispersibility, high printability, and low contractibility, which are essential to achieving a high stacking capability and the modularization of electronic parts, as well as substrate materials and high-reliability products that can replace solder products to meet the growing demand for electrical and electronic parts.
Also, attempts are being made in parallel to develop new materials that can replace expensive precious-metal fillers that have been applied thus far.

We are aiming to achieve total solutions for addressing electromagnetic wave and heat dissipation issues and have developed noise suppressors using various types of magnetic materials and addressed heat dissipation issues by applying high-temperature conductive fillers. We are now designing and developing a series of EMC products with outstanding shielding, conduction, and cooling performance.

Clad metal refers to a material where two or more different kinds of metals are bonded through pressure welding (hot, cold, and explosion).

Sintered bearings are essential components for home appliances, office appliances, and IT technology, and especially for electronic and automotive parts. Our 35 years of accumulated technology has allowed us to develop high precision sintered bearings with micrometer level dimensional accuracy while providing a range of economic advantages and outstanding characteristics.
We are expanding our boundaries into heavy alloy fields such as anti-vibration bars, shielding materials with our high-density and high-strength sintered bearing manufacturing techniques and binder design technology for tungsten heavy alloys.
We are also developing the raw materials of the W-Cu alloys which have excellent thermal affinity with LED chips and outstanding heat dissipation performance to respond to the increasing demand for solutions to heat management issues associated with high-power LED applications.
