Nickel-plated molybdenum square sheet
Molybdenum substrate
Molybdenum substrate for microelectronics
LED chip
LED polished molybdenum substrate
Polished molybdenum substrate for LED luminous chips
The product is mainly used as substrate for high power LED light-emitting chip, mainly used in high power
LED light chip, such as urban landscape lighting, car LED light, etc., the main user package
Including South Korea Seoul Semiconductor, Japan Samsung, SAN An photoelectric giants, market prospects ten
Divide broad.
Molybdenum is a substrate with high melting point, low thermal expansion rate and high thermal conductivity
Reliable heat dissipation performance, which plays an important role in the semiconductor field, is power electronics half
Conductor ideal chip support material. Our company produces LED lighting chip with molybdenum substrate
Heat dissipation, flatness, roughness and finish have reached the international top level, and
And it is unique in China.
