High heat resistance and high insulation thermosetting resin
improves functionality and reliability of electric power train.

Special Molding Compound
for power control module

We have developped high reliabiity EMC (Epoxy molding compund) which has high heat resistance, heat dissipation and insulation perfomance for power device. We can also provide your PKG design flexiblity and high productivity by transfer molding system.


Excellent properties (insulation, heat dissipation, heat resistance, and adhesiveness) contribute to miniaturization and high performance.
