Some of the factors are discussed below.<\/p>\n<div align=\"justify\">\n<ul>\n<li>Heavy copper PCBs are manufactured using variety of etching and plating techniques. This helps ensure even copper thickness to the plated holes, and sidewalls. The choice of the right technique should be made after analyzing future application of the circuit.<\/li>\n<li>Heat is dissipated through various mechanisms &#8211; radiation, convection, conduction. Therefore, extra care should be taken to carry away heat generated. This will help reduce failure of components. Heavy Copper conductors must be fitted with a heat sink to dispense all the heat generated.<\/li>\n<li>The relationship between Minimum Line Spaces (Min LS) and Minimum Line Width should be taken into consideration in order to meet the design constraint of the standard heavy copper PCB.<\/li>\n<\/ul>\n<\/div>\n<p align=\"justify\"><strong>Advantages of Heavy Copper PCB<\/strong><\/p>\n<p align=\"justify\">Heavy copper PCBs are normally used in high power transmission applications due to several advantages they offer. Let us look at few of them.<\/p>\n<div align=\"justify\">\n<ul>\n<li>Heavy base copper allows delivery of consistent and reliable power.<\/li>\n<li>The external heat sink fitted inside the panel of heavy copper PCB allows the dissipation of heat carried by the copper plate of about 120 oz.<\/li>\n<li>The I2R losses are reduced in heavy copper PCB\u2019s by taking heat away from valuable components, therefore reducing failure rates.<\/li>\n<li>Multiple copper weights on the same layer of circuit gives the product a compact shape and size.<\/li>\n<li>High-current circuits and control circuits are integrated on a single PCB, thus offering increased current carrying capacity, and higher tolerance to thermal strains<\/li>\n<\/ul>\n<\/div>\n<p align=\"justify\"><strong>Applications of Heavy Copper PCB<\/strong><\/p>\n<p align=\"justify\">The following are a few important industrial applications that are driven by heavy copper PCBs.<\/p>\n<div align=\"justify\">\n<ul>\n<li>Power supplies for weapons control systems.<\/li>\n<li>Planar transformers<\/li>\n<li>Energy storage and power grid back up<\/li>\n<li>Nuclear power applications<\/li>\n<li>Line reactors panels<\/li>\n<li>Hydro-electric plants<\/li>\n<li>Amplification systems.<\/li>\n<\/ul>\n<\/div>\n<p align=\"justify\">There is a growing demand for <a href=\"http:\/\/www.rigiflex.com\/heavy-copper-pcbs\">heavy copper PCB <\/a>in many industries. These PCBs are known for excellent thermal management in various applications which makes them popular.
