Additional thicker copper helps the PCB provide much higher currents than its base materials would otherwise allow, but it also affects other design features such as <strong>the width of the traces or the space between them<\/strong>. When using thicker copper, <span style=\"color: #008000;\">the traces that connect different parts of the PCB should be made wider to accommodate it.<\/span><\/div><div class=\"ace-line ace-line old-record-id-HTmmdcW4BojEhoxnUcCcfdWznBc\">Wider traces are preferred because they <strong>reduce the resistance and stop the board from heat<\/strong> when it\u2019s flowing large currents. On the other hand, if the traces are too narrow the resistance will be high can lead to heat generation which is not good for the board or may hamper the performance. Furthermore, as copper thickness gets bigger, <span style=\"color: #008000;\">you have to provide more space between the lines in order not to have shorting or even some electrical coupling that is undesired.<\/span><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6a1c51f elementor-widget elementor-widget-image\" data-id=\"6a1c51f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"700\" height=\"440\" src=\"https:\/\/www.elepcb.com\/wp-content\/uploads\/2024\/10\/What-is-Heavy-Copper-PCB.png\" class=\"attachment-large size-large wp-image-14103\" alt=\"What is Heavy Copper PCB\" srcset=\"https:\/\/www.elepcb.com\/wp-content\/uploads\/2024\/10\/What-is-Heavy-Copper-PCB.png 700w, https:\/\/www.elepcb.com\/wp-content\/uploads\/2024\/10\/What-is-Heavy-Copper-PCB-300x189.png 300w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-e40891c elementor-widget elementor-widget-text-editor\" data-id=\"e40891c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>As a clearer picture of how copper thickness plays out to the design below is the following table that illustrates the copper thickness to minimum trace width and maximum current capacity.
