  • Strengths of miniaturization

    Strengths of
    miniaturization

    In the 1980s, we succeeded in developing compact crystal devices ahead of other companies, and for more than 30 years since then, we have taken the lead in developing and investing in miniaturization of surface-mount crystal units. Our customers have given us the evaluation that "small size = RIVER ELETEC". Smaller, thinner, and lighter. Most of all we help to reduce carbon footprint.

  • Strengths of microfabrication

    Strengths of
    microfabrication

    We have independently developed the crystal MEMS processing manufacturing process and production equipment that apply semiconductor photolithography technology, and have achieved high performance and high quality through quality control on the submicron order.

  • The only encapsulation technology in the world [Electron beam encapsulation/EBS]

    The only encapsulation technology in the world
    [Electron beam encapsulation/EBS]

    The electron beam sealing method is a method of welding a metal lid to a ceramic package using an electron beam. It was originally developed by RIVER ELETEC and has a sales record of more than 25 years. Heating in a high vacuum (1 Pa or less) for an extremely short time of a few milliseconds ensures stable high quality with little damage to the elements.

  • Succeeded in mass production of crystal wafer level packages [Direct metal-to-metal bonding/MDS]

    Succeeded in mass production of crystal wafer level packages
    [Direct metal-to-metal bonding/MDS]

    Succeeded in practical use of wafer-level packaging, which is the key to next-generation miniaturization. The first Crystal Case® product, TFX-05X, was released in 2018 and has been well received in the market.

  • High market share of tuning fork crystals

    High market share of
    tuning fork crystals

    The elemental technologies that support our tuning fork products are our own EBS and microfabrication photolithography process. With a photolithography processing accuracy of 1 μm or less, it achieves stable impact resistance and the industry's lowest R1. We aim to become a global standard in response to the demand for ultra-low power consumption of LPWA and smartphones.

  • Responsiveness and speed of delivery

    Responsiveness and
    speed of delivery

    Our strength lies in customer support through the trinity of sales, development, and manufacturing. We have received a comprehensive evaluation of our products, such as specifications with a high degree of difficulty, provision of samples in a short period of time, matching services for individual customer circuits, and delivery times. support. For trading companies, we contribute to improving sales efficiency and supporting customer development.

  • High quality and guarantee

    High quality and guarantee

    We provide services that are made in Japan and meet the expectations and demands of our customers. We have acquired ISO9001 certification, the international standard for quality management systems, and supply lead-free compliant products regulated by the RoHS Directive (2011/65/EU and (EU) 2015/863).

  • In-house designed equipment Product supply capacity

    In-house designed equipment Product supply capacity

    We provide internationally competitive products with our own design facilities and production know-how. Our production facilities are capable of switching production for a wide variety of products, allowing us to respond to sudden demand through flexible manufacturing system.

  • Pursuing the possibilities of crystal oscillators (1) high frequency oscillator

    Pursuing the possibilities of crystal oscillators (1)
    high frequency oscillator

    RIVER ELETEC will continue to explore various new values for crystal oscillators.

    Our newly discovered KoT cut OPAW oscillator, which is a type of plate wave, has achieved unprecedented low noise and frequency accuracy with a fundamental vibration of 491.52 MHz to 1 GHz, and will provide new value.

  • Pursuing the possibilities of crystal oscillators (2) 200°C compatible

    Pursuing the possibilities of crystal oscillators (2)
    200℃ compatible

    RIVER ELETEC will continue to explore various new values for crystal oscillators.

    Succeeded in mass production of GT-cut crystal units that generate stable frequencies over a wide temperature range. It achieves ±50ppm frequency accuracy in the temperature range up to 200°C, and can be used as a clock source in new and challenging environments where no other oscillator is able to.
