Small-size copper-clad aluminum strips have high dimensional accuracy and special application scenarios (such asPhotovoltaic welding ribbon<\/a>, precision connectors, microelectronic circuits, etc.) have more stringent technical requirements in production and use. The following are the main technical requirements for small-sized copper-clad aluminum strips:<\/p>

\ud83e\udde9 1. Dimensional accuracy requirements<\/h3>
  1. Thickness tolerance<\/strong>: \u00b10.005 mm or less (customizable)<\/li>\n\n
  2. Width tolerance<\/strong>: \u00b10.02 mm or less<\/li>\n\n
  3. Edge uniformity<\/strong>: No burrs, no cracks, no curling<\/li>\n\n
  4. Flatness requirements<\/strong>: Flat, no warping, curvature less than 1.5\u2030<\/li><\/ol>

    \u2699\ufe0f 2. Composite structure quality requirements<\/h3>
    1. Copper layer thickness<\/strong>\uff1a\u22650.02 mm (varies according to specifications)<\/li>\n\n
    2. Copper layer uniformity<\/strong>\uff1aThe copper layer thickness is evenly distributed on the strip surface, and the fluctuation shall not exceed \u00b110%<\/li>\n\n
    3. Copper-aluminum bonding strength<\/strong>: Must meet metallurgical bonding standards and must not peel or delaminate<\/li>\n\n
    4. Interface integrity<\/strong>: No bubbles, inclusions, or voids<\/li><\/ol>

      \ud83e\uddea 3. Electrical performance requirements<\/h3>
      1. Electrical conductivity (IACS)<\/strong>\uff1aGenerally \u226565%, high conductivity products can reach \u226575%<\/li>\n\n
      2. Resistivity<\/strong>\uff1aMust meet photovoltaic industry or electronic grade requirements (based on thickness and copper layer control)<\/li>\n\n
      3. Welding performance<\/strong>\uff1aGood tin adhesion, no oxide layer, easy to tin<\/li><\/ol>

        \ud83e\uddf1 4. Mechanical performance requirements<\/h3>
        1. tensile strength<\/strong>\uff1aGenerally required to be \u2265120 MPa, high strength or high ductility types can be customized according to the application<\/li>\n\n
        2. Elongation<\/strong>\uff1a\u226510% (soft state), ensuring flexibility<\/li>\n\n
        3. Bending properties<\/strong>: 180\u00b0 repeated bending for no less than 5 times without breakage<\/li><\/ol>

          \ud83e\uddfc 5. Surface quality requirements<\/h3>
          1. Surface finish<\/strong>: No scratches, indentations, oil stains, water stains, etc.<\/li>\n\n
          2. Surface oxidation control<\/strong>\uff1aThe copper surface needs to be passivated or protected to avoid oxidation and blackening<\/li>\n\n
          3. No exposed aluminum on the surface<\/strong>: The copper layer must completely cover the aluminum core, and there must be no obvious aluminum exposure<\/li><\/ol>

            \ud83d\udce6 6. Packaging and storage requirements<\/h3>
            1. Vacuum sealed or dry packed<\/strong>, to prevent moisture oxidation<\/li>\n\n
            2. Neatly roll or slice to prevent crushing or curling<\/strong><\/li>\n\n
            3. Clear labeling, including specifications, batch number, production date, etc.<\/strong><\/li><\/ol>

              \u2705 7. Ruichuang\u2019s technical advantages (with examples)<\/h3>
              • High precision rolling technology<\/strong>\uff1aCan achieve thickness control below 0.05mm, suitable for micro-narrow bands<\/li>\n\n
              • Online detection system<\/strong>: Real-time monitoring of copper layer thickness and bonding to ensure consistency<\/li>\n\n
              • Multiple annealing + leveling technology<\/strong>: The strip has both softness and strength, suitable for automatic welding<\/li><\/ul>

                If you have specific specifications (such as 0.1\u00d72mm, 0.15\u00d74mm, etc.) and uses, I can further help you customize the recommended technical parameters or evaluate whether it is suitable. Do you want me to help you compile a list of recommended specifications?<\/p>","protected":false},"excerpt":{"rendered":"
