data-internallinksmanager029f6b8e52c=\"43\" title=\"Photovoltaic welding ribbon\">Photovoltaic welding ribbon<\/a>The reason why the tin plating thickness is different is mainly due to the following needs and technical requirements:<\/p>\n<hr \/>\n<h3>1. <strong>Welding performance requirements<\/strong><\/h3>\n<ul>\n<li><strong>Thick tin coating<\/strong>:\n<ul>\n<li><strong>Enhanced weldability<\/strong>\uff1aThick tin plating layer can provide more solder material, which helps to form a strong solder joint during welding and reduce the possibility of false solder joints or false solder joints.<\/li>\n<li><strong>Adapt to low temperature welding process<\/strong>\uff1aSome new components use low temperature soldering technology, and the thick tin plating layer can compensate for the insufficient wettability caused by low temperature soldering.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Thin tin coating<\/strong>:\n<ul>\n<li><strong>Reduce solder waste<\/strong>: For high-precision automatic soldering equipment, too thick a tin plating layer may result in excessive solder, causing overflow or excess tin slag.<\/li>\n<li><strong>Reduce costs<\/strong>: Reducing the amount of tin can reduce overall costs, especially in large-scale production.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<hr \/>\n<h3>2. <strong>Component types and design requirements<\/strong><\/h3>\n<ul>\n<li><strong>Traditional components<\/strong>:Tradition<a href=\"https:\/\/www.ray-tron.com\/en\/\" data-internallinksmanager029f6b8e52c=\"14\" title=\"Photovoltaic modules\">Photovoltaic modules<\/a>The requirement for the thickness of the tin plating layer of the welding strip is relatively low, usually just to ensure the firmness of the welding.<\/li>\n<li><strong>High efficiency components<\/strong>\uff1aHigh-efficiency components (such as PERC, HJT, etc.) require higher soldering quality, so thicker or more uniform tin plating may be required.<\/li>\n<li><strong>Bifacial modules<\/strong>: Bifacial power generation modules may require higher consistency in welding and more precise control of tin plating thickness.<\/li>\n<\/ul>\n<hr \/>\n<h3>3. <strong>Influence of the use environment<\/strong><\/h3>\n<ul>\n<li><strong>Harsh environment applications<\/strong>:\n<ul>\n<li>In high temperature, high humidity or salt spray environments, thicker tin plating layers can provide better corrosion resistance and longer service life.<\/li>\n<\/ul>\n<\/li>\n<li><strong>General environment application<\/strong>:\n<ul>\n<li>In milder environments, the tin plating layer can be appropriately reduced to save material costs while still meeting basic anti-oxidation properties.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<hr \/>\n<h3>4. <strong>Customer and equipment requirements<\/strong><\/h3>\n<ul>\n<li><strong>Customer needs<\/strong>:\n<ul>\n<li>Different PV module manufacturers may have different requirements for the thickness of solder ribbon tinning, which mainly depends on their process preferences and module design.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Welding equipment adaptation<\/strong>:\n<ul>\n<li>Automatic string soldering machines usually have stricter requirements on the tin plating thickness of the solder strip to ensure that the wettability and fluidity of the tin during soldering meet the equipment standards.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p><img fetchpriority=\"high\" decoding=\"async\"
