In the fields of electrical connections, automotive electronics, new energy batteries, precision manufacturing, etc., there is a "low-key but critical" material that is playing an irreplaceable role.Small size copper strip<\/a><\/strong>.<\/p>\n\n\n\n

It is as small as a millimeter, but it is responsible for conducting current, connecting components, and maintaining the stable operation of the system. You may never notice its existence, but as long as it has a flaw, the entire system may not work properly.<\/p>\n\n\n\n

Today, let\u2019s talk about this seemingly inconspicuous copper strip, which is known as \u201cconnecting the nerve endings of industry\u201d - and a professional manufacturing company that is highly trusted in the industry:Raytron<\/a>Raytron<\/a><\/strong>.<\/p>\n\n\n\n

In what fields are small-sized copper strips used?<\/h3>\n\n\n\n

Don't underestimate it because it is small. It has many uses:<\/p>\n\n\n\n

    \n
  • \u2705 Battery connector<\/strong>: Key conductor materials for lithium batteries, power tool batteries, and electric vehicle batteries;<\/li>\n\n\n\n
  • \u2705 Terminal connection copper sheet<\/strong>: Widely used in automobiles, home appliances, and communication equipment;<\/li>\n\n\n\n
  • \u2705 Precision electronic components<\/strong>: Such as FPC soft board, PCB connection, electromagnetic shielding, etc.;<\/li>\n\n\n\n
  • \u2705 New energy vehicle wiring harness terminals<\/strong>: High-speed data transmission and current transmission carrier.<\/li>\n<\/ul>\n\n\n\n

    These scenarios have extremely stringent requirements on copper strips: high conductivity, high ductility, anti-oxidation, stable dimensional accuracy...and this is why not all manufacturers are capable of producing small-sized copper strips.<\/p>\n\n\n\n

    \n\n\n\n

    Why is it so difficult to make small-sized copper strips?<\/h3>\n\n\n\n

    You may think: copper strips are just made by drawing and cutting thinner, right? But the truth is far more complicated than you think.<\/p>\n\n\n\n

    Small size copper strip, especiallyThickness as low as 0.05mm, width less than 10mm<\/strong>The requirements for the production process of high-quality products can be described as "the truth is determined by every millimeter".<\/p>\n\n\n\n

      \n
    • High purity requirements for raw materials<\/strong>: High-precision copper or electrolytic copper must be used, with extremely low impurity content;<\/li>\n\n\n\n
    • The ultimate challenge of rolling technology<\/strong>\uff1aIt requires precision equipment with more than four continuous rolling mills and an experienced operation team;<\/li>\n\n\n\n
    • Size control must be extremely precise<\/strong>: The thickness tolerance is controlled at \u00b10.005mm, and the width consistency control must be stable;<\/li>\n\n\n\n
    • Surface treatment is critical<\/strong>: There should be no burrs, scratches, oil stains, and it should not be easily oxidized and discolored.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Who can make high-standard small-size copper strips? Ruichuang gives the answer<\/h3>\n\n\n\n

      As a national high-tech enterprise focusing on small-sized copper strips,Raytron<\/strong>As early as 2012, it began to deeply cultivate the research and development of calendering technology. Today, it has grown into one of the most representative small-size flat wire\/copper strip manufacturers in China.<\/p>\n\n\n\n

            The trend has come, and the market potential of small-sized copper strips is huge<\/h3>\n\n\n\n

            With the explosive growth of new energy vehicles, energy storage, consumer electronics, and 5G equipment, the demand for high-precision small-size copper strips is rising rapidly.<\/p>\n\n\n\n

            Whoever can provide more stable, higher precision and more deliverable materials will have the initiative in manufacturing upgrades.<\/p>","protected":false},"excerpt":{"rendered":"
