The following are the key points to pay attention to when using copper clad aluminum strip:<\/p><hr class=\"wp-block-separator has-alpha-channel-opacity\"\/><h3 class=\"wp-block-heading\">\u2705 1. Precautions for using copper-clad aluminum strip:<\/h3><h4 class=\"wp-block-heading\">1. <strong>Avoid excessive bending or repeated folding<\/strong><\/h4><ul class=\"wp-block-list\"><li>Reason: Copper-clad aluminum strip is composed of a copper layer and an aluminum core. Repeated bending may cause the copper layer to crack, delaminate or peel off.<\/li>\n\n<li>Recommendation: Try to control the bending radius during construction and avoid sharp bends.<\/li><\/ul><h4 class=\"wp-block-heading\">2. <strong>Avoid exposure to high humidity and high corrosive environment<\/strong><\/h4><ul class=\"wp-block-list\"><li>Reason: Aluminum is more susceptible to oxidation. If the copper layer is damaged or too thin, moisture may penetrate and cause internal corrosion.<\/li>\n\n<li>Recommendation: In outdoor or humid environments, packaging or protective measures (such as backplane packaging, film wrapping, etc.) must be taken.<\/li><\/ul><h4 class=\"wp-block-heading\">3. <strong>Welding temperature and time need to be strictly controlled<\/strong><\/h4><ul class=\"wp-block-list\"><li>Reason: The melting point of aluminum is lower than that of copper. If the temperature is too high or the duration is too long during welding, it is easy to cause oxidation or interface separation.<\/li>\n\n<li>Recommendation: Choose appropriate flux and welding process (such as hot air welding, infrared welding), and strictly control temperature, time and pressure.<\/li><\/ul><h4 class=\"wp-block-heading\">4. <strong>Prevent copper layer from being damaged or scratched<\/strong><\/h4><ul class=\"wp-block-list\"><li>Reason: The copper layer has limited thickness, and the aluminum core is easily exposed after being scratched, which affects conductivity and accelerates oxidation.<\/li>\n\n<li>Recommendation: Keep edge protection during transportation, cutting, winding and installation, and use dust-free soft gloves and scratch-free clamps.<\/li><\/ul><h4 class=\"wp-block-heading\">5. <strong>Storage conditions should be dry and sealed<\/strong><\/h4><ul class=\"wp-block-list\"><li>Reason: It is easy to absorb moisture and oxidize when exposed to the air, causing the surface to turn black and affecting welding and conductivity.<\/li>\n\n<li>Recommendation: Use desiccant to seal the package and place it in a ventilated, dry environment without corrosive gases (recommended temperature 5-30\u2103, humidity &lt;60%RH).<\/li><\/ul><h4 class=\"wp-block-heading\">6. <strong>Match and adjust device parameters<\/strong><\/h4><ul class=\"wp-block-list\"><li>Reason: The hardness, ductility and thermal sensitivity of copper-clad aluminum strip are different from those of pure copper strip.<\/li>\n\n<li>Recommendation: Pre-adjust parameters and conduct trial production on cutting, welding, calendering and other equipment to avoid problems such as breakage and poor welding during production.<\/li><\/ul><hr class=\"wp-block-separator has-alpha-channel-opacity\"\/><h3 class=\"wp-block-heading\">\u26a0\ufe0f Special Note:<\/h3><ul class=\"wp-block-list\"><li>Too thin copper layer or poor bonding is a common problem of low-quality CCA tape. Before using, you should ensure that the supplier provides<strong>Cross-sectional metallographic photos, peeling force test, conductivity test and other quality inspection reports<\/strong>.<\/li>\n\n<li>It is recommended to choose manufacturers with high-end calendering and compounding technology capabilities (such as<a href=\"https:\/\/www.ray-tron.com\/en\/\" data-internallinksmanager029f6b8e52c=\"19\" title=\"Ruichuang 2\">Raytron<\/a>) to ensure the consistency of copper layer thickness and composite strength.<\/li><\/ul>","protected":false},"excerpt":{"rendered":"<p>Copper clad aluminum ribbon (CCA ribbon) is used as a photovoltaic welding ribbon or conductor material.
