    📋 Usage and Storage Guide

    🌡️ Reflow Temperature

    Reflow at 138°C for clean, reliable solder joints. Do not exceed 160°C.

    Use a hot air station or reflow oven for best results.

    ❄️ Storage Conditions

    Store in a cool, dry place away from direct sunlight. Keep container sealed when not in use.

    Refrigeration extends shelf life. Use within 6 months once opened.

    🔧 Application Tips

    Apply with a dispensing needle or small spatula for accuracy. Use a stencil for consistent BGA pad coverage.

    Clean excess flux residue after reflow for a professional finish.

    ⚠️ Important — Low Temp Only Applications

    Use RELIFE RL-404 only where low-temperature solder is appropriate.

    Do not mix with standard SAC305 or Sn63/Pb37 solder. Mixing alloys creates weak joints.

    Not suitable for applications that regularly reach above 120°C in operation.

    RELIFE RL-404 FAQ

    What is low temperature solder paste used for?
    Low temp solder paste is used for heat-sensitive repairs. It melts below 150°C. This protects delicate components like CPUs and memory chips. Common uses include BGA reballing, SMT work, and logic board repairs.
    What is the melting point of RELIFE RL-404?
    RELIFE RL-404 melts at exactly 138°C. This is much lower than standard solder (183–220°C). The low melting point keeps boards and chips safe during rework.
    Is RELIFE RL-404 lead-free?
    Yes. RELIFE RL-404 is 100% lead-free. It uses a Sn42/Bi58 (Tin-Bismuth) alloy formula. This makes it safe for technicians and environmentally friendly.
    What is Sn42/Bi58 solder alloy?
    Sn42/Bi58 is a tin and bismuth alloy. It contains 42% tin and 58% bismuth. This combination creates a eutectic alloy that melts at a stable 138°C. Bismuth lowers the melting point without adding lead.
    What components can I use RL-404 on?
    Use RL-404 on BGA chips, SMD pads, SMT patches, and multi-layer logic boards. It is ideal for smartphone and tablet motherboard repairs. Use it wherever standard solder heat would damage nearby parts.
    What is BGA reballing?
    BGA (Ball Grid Array) reballing replaces the solder balls on a chip. Worn or cracked balls cause board faults. RL-404 paste is applied to a stencil, then reflowed to form new balls. Low temp paste protects the chip during this process.
    How do I store RELIFE RL-404 solder paste?
    Store in a cool, dry place away from sunlight. Keep the lid sealed tightly when not in use. Refrigeration extends shelf life. Use within 6 months of opening for best results.
    Can I mix RL-404 with standard solder paste?
    No. Never mix RL-404 with standard SAC305 or Sn63/Pb37 solder paste. Mixing alloys creates unstable joints that fail early. Always clean old solder fully before applying RL-404.
