    Core capacity advantage

    With an annual production capacity of 6 million cores, it has completely broken the pattern of foreign monopoly of the cores.

    3
    Packaging capacity advantage

    The first packaging line with an annual output of 2 million pressure sensors was successfully put into production. Follow-up will continue to expand production.
