Nihon Dempa Kogyo: Developed next-generation crystal unit: Essential for 5G smartphones
Nihon Dempa Kogyo:
Nihon Dempa Kogyo has developed a next-generation crystal unit.
“Crystal parts manufacturing technology that controls the movement of electronic devices” has entered a new stage.
Conventional:
Machining was the mainstream manufacturing technology for crystal parts that control the movement of electronic devices.
this time:
Nihon Dempa Kogyo utilizes a semiconductor manufacturing method.
Over 10 years, we have developed mass production technology for making small and thin crystals.
5G compatible crystal unit:
Crystal parts for 5G smartphones are difficult to make except by new manufacturing methods.
Japan’s original technology:
Taiwan and others were on the offensive with low-priced products.
However, overseas companies have not succeeded in mass production using the new manufacturing method.
Japanese companies have secured a competitive advantage with their own technology.
“Industrial salt”:
Crystal parts are electronic control unit ECUs for smartphones and automobiles.
Inside a watch or the like, it creates a reference signal for other parts to move accurately.
It utilizes the property of trembling when a voltage is applied to a crystal unit with electrodes attached to a crystal section.
Conventionally machined:
Crystal oscillators are mainly manufactured by machining such as cutting and polishing.
This time photolithography blank processing:
A Japanese manufacturer has developed mass production technology by “photolithography blank processing”.
Nihon Dempa Kogyo:
Development started more than 10 years ago.
Although it was possible to mass-produce it five years ago, the superiority of photolithography processed products was not high in 4G smartphones.
60% miniaturization:
The tide changed in 2020, when 5G smartphones began to spread.
The thickness of the crystal unit was reduced to 0.5 mm to support high frequencies.
With a 5G smartphone, it was necessary to make it 1 mm square.
Crystal Oscillator Price:
The average large price of a crystal unit is around 15 yen per unit.
Approximately 15% increase from the same period of the previous year.
The first business opportunity in 20 years has arrived.
