The commonly materials are FR4 and PI. FR4 is a widely acceptable international grade for fiberglass reinforced epoxy laminated, and it always used for making rigid PCB or <a href=\"https:\/\/www.bestfpc.com\/Products\/Rigid_Flex_PCB\/\" title=\"\">rigid-flex PCB<\/a>. FR4 substrate has good insulation and mechanical strength, so it can be widely used in various applications. However, PI has higher heat and chemistry resistance, more suitable for high temperature and chemical corrosion environment. \u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Circuit_Layout\"><\/span>Circuit Layout<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The layout design depends on the dimensions, performance and reliability of a circuit board, it is needed to follow your supplier\u2019s standard to make sure the fast production time and high quality.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Min line width<\/li>\n<\/ul>\n\n\n\n<p>Please make sure your line width within your supplier\u2019s manufacturing capability, that is to say, if it is less than the minimum line width will not able to be produced. The best way is if the design conditions available, the larger the line width, the better the factory production. Generally, the <a href=\"https:\/\/www.bestpcbs.com\/about\/capability.htm\" title=\"\">line width<\/a> keeps around 10mil is the best. In another word, if your line width is less than normal standard, it would be difficult for you to find a suitable supplier.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Min line spacing<\/li>\n<\/ul>\n\n\n\n<p>Min line spacing means the distance between trace and trace. Normally, from the production aspect, the distance from line to pads should not less than min<a href=\"https:\/\/www.bestpcbs.com\/about\/capability.htm\" title=\"\"> line spacing<\/a>, and it would be better if it is larger, generally equal to or more than 10mil.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The spacing between circuit to outline should be control in 20mil.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"How are PCBs produced?

That is to say, if the pin of components is 0.6mm, then the plug-in holes should be greater than 0.8mm. Otherwise, the plug-in components would be probably difficult to insert into PCB because of the tolerance control during the manufacturing and <a href=\"https:\/\/www.bestpcbs.com\/products\/pcba.htm\" title=\"\">assembly<\/a>.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Min_Hole_Diameter\"><\/span>Min Hole Diameter<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>As we all know, the holes in PCB almost be used for mounting components, connect circuit and provide the electrical connection between layers. So how to design the hole also is crucial during the designing. Generally, the min hole diameter depends on the drill bitter that vendor used, always around 0.2-0.4mm. You can ask your supplier during the design evaluation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Copper_Thickness\"><\/span>Copper Thickness<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Copper foil is a layer of metal foil on the <a href=\"https:\/\/www.bestpcbs.com\/products\/multi-layer-pcb.htm\" title=\"\">PCB board<\/a> that is used to conduct current. The thickness of copper foil is usually in oz (ounces), such as 1oz, 2oz, 3oz, etc. The thickness of the copper foil will affect the conductivity and heat dissipation performance of the PCB board.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Impendence_Control\"><\/span>Impendence Control<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Impedance control is a key parameter in high-speed signal transmission and high-frequency circuit design. It involves board thickness, copper foil thickness, substrate dielectric constant, pad and line layout and other factors to improve the signal integrity and anti-interference ability of the PCB board.<\/p>\n\n\n\n<p>The <a href=\"https:\/\/www.bestpcbs.com\/manufacturing\/pcb-manufacturing.htm\" title=\"\">production process<\/a> of PCBs is rather complex, involving a wide range of techniques from simple mechanical processing to sophisticated machining, so you should understand the design rules very clearly when you are trying to design a PCB board. Its applications are also diverse, from consumer electronics to industrial machinery, where PCBs are utilized.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.bestpcbs.com\/\" title=\"\">EBest Circuit (Best Technology)<\/a> offers one-stop PCB solutions, we offer service from <a href=\"https:\/\/www.bestpcbs.com\/about\/pcb-prototype.htm\" title=\"\">prototyping<\/a> to large-scale production and assembly.
