    Nihon Superior Is Setting New Standards in Lead-Free Soldering Technology at APEX 2024

    Nihon Superior APEX 24

    Nihon Superior Co. Ltd., an advanced joining material supplier, will exhibit in Booth 1325 during the 2024 IPC APEX EXPO, scheduled to take place April 9-11, 2024 at the Anaheim Convention Center in California. Renowned for its commitment to innovation, Nihon Superior will present a range of groundbreaking products, including the SN100CV® P608 solder paste and the TempSave™ series of low-temperature soldering materials.

    SN100CV® P608 sets a new standard as a completely halogen-free, lead-free, and no-clean solder paste by Nihon Superior. In contrast to silver-containing alloys relying on a dispersion of fine particles of eutectic Ag3Sn for strength, SN100CV achieves its robustness from solute atoms within the tin matrix of the joint. Remarkably, in tensile tests, SN100CV matches the strength of SAC305 while retaining a high resistance to impact loading, offering exceptional performance in various applications.

    For high-reliability applications demanding strength surpassing SAC305, Nihon Superior
    introduces the LF-C2 lead-free alloy. Leveraging both dispersion and solid solution strengthening,
    LF-C2 delivers superior strength. With a liquidus temperature of 213°C, it facilitates reflow at a
    lower temperature than SAC305.

    The P608 flux medium ensures wetting comparable to halogen-containing pastes, despite being
    completely halogen-free. SN100CV P608 and LF-C2 exhibit outstanding performance across
    diverse component types and process parameters.

    Additionally, Nihon Superior presents the TempSave™ series of low-temperature soldering materials, addressing industry goals such as reducing peak reflow temperature, minimizing package warpage, lowering energy consumption during reflow, and protecting temperature sensitive devices.

    • TempSave B58: A eutectic SnBi alloy with a low melting point of 139°C.
    • TempSave B37: A ductile hypoeutectic SnBi alloy without Ag, offering exceptional drop performance, surpassing SAC305. The P610 flux medium, specifically designed for Bi alloys, ensures halogen-free compatibility. The TempSave B37 P610 solder paste can be reflowed with a peak temperature of 190°C. Additionally, a high-speed jetting paste version, TempSave B37 P611, provides consistent dot sizes.
