In this section, we&#8217;re looking at industry-recommended ways that you can tweak your circuit board design to improve efficiency:<\/p>\n\n\n\n<p>First, use a do-it-yourself (DIY) approach to create the schematic. Doing so lets you know the critical circuit parts&#8217; exact design and placement. <\/p>\n\n\n\n<p>Next, space the components while avoiding placing traces at right angles. We recommend adopting a 45\u00b0 angle to avoid overcrowding the board.&nbsp;<\/p>\n\n\n\n<p>Also, place components while adhering to a uniform orientation to make soldering them easier. Fourth, determine the best line width to ensure sufficient current flows. <\/p>\n\n\n\n<p>Fifth, create a ground plane to ensure constant current flows throughout your circuit. Lastly, add <a href=\"https:\/\/en.wikipedia.org\/wiki\/Heat_sink\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">heat sinks<\/a> to potential heat spots within the circuit.<\/p>\n\n\n\n<p>Failure to do so will lead to overheating, which may damage the board.&nbsp;&nbsp;<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"causes-of-circuit-board-failures\">Causes of Circuit Board Failures<\/h2>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/3-42.jpg\" alt=\"A PCB with damage from electrical short circuits\" class=\"wp-image-3056\" srcset=\"https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/3-42.jpg 1000w, https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/3-42-300x200.jpg 300w, https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/3-42-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">(A PCB with damage from electrical short circuits)<\/p>\n\n\n\n<p>If you&#8217;re using a computer, you may notice it getting slower with age. Mainly, manufacturers will indicate the length of time that one can use a device before it starts developing issues.<\/p>\n\n\n\n<p> However, some people use devices for periods well above what the manufacturer expects. So, here, we&#8217;re giving you the most common reasons for <a href=\"https:\/\/yourpcb.com\/how-to-test-if-circuit-board-is-orking\/#more-3019\" target=\"_blank\" rel=\"noreferrer noopener\">circuit board failures<\/a>.&nbsp;<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"environmental-factors\">Environmental Factors<\/h3>\n\n\n<p>Any weather elements affecting electrical circuits will cause your circuit board to fail. Generally, exposing uninsulated electrical components to rain will lead to deterioration. <\/p>\n\n\n\n<p>Therefore, the same applies to circuit boards, as they are prone to failure due to corrosion and short circuit.&nbsp;<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"electrical-overload\">Electrical Overload<\/h3>\n\n\n<p>If you look at your power cable, you will notice they have an adapter. In other cases, you&#8217;ll notice that the socket has some form of a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Fuse_(electrical)\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">fuse<\/a>. <\/p>\n\n\n\n<p>Fuses cut out power to the device in the case of an overload. And an overload is a situation whereby a voltage spike occurs, causing the power cable to pass excess power to your circuit board. <\/p>\n\n\n\n<p>Consequently, it will damage your board or cause some components to fail.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"physical-damage\">Physical Damage<\/h3>\n\n\n<p>Circuit boards are delicate electrical pieces that have little tolerance to physical stress. Therefore, any force that bends the board will cause it to fail as it breaks its circuitry. <\/p>\n\n\n\n<p>Moreover, any physical stress that damages critical components, such as the CPU, will damage it.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"electromagnetic-interference-emi\">Electromagnetic Interference (EMI)<\/h3>\n\n\n<p>Keeping your circuit board close to a source that generates massive EMI will interrupt its signals and communication. Furthermore, it may disrupt the power supply causing some components to malfunction.&nbsp;<\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-repair-circuit-boards\">How To Repair Circuit Boards<\/h2>\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"667\" src=\"https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/4-38.jpg\" alt=\"A man repairing a circuit board\" class=\"wp-image-3055\" srcset=\"https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/4-38.jpg 1000w, https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/4-38-300x200.jpg 300w, https:\/\/yourpcb.com\/wp-content\/uploads\/2023\/03\/4-38-768x512.jpg 768w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p class=\"has-text-align-center\">(A man repairing a circuit board)<\/p>\n\n\n\n<p>Repairing printed circuit boards is easy, especially if you know what you&#8217;re doing:<\/p>\n\n\n\n<p>First, you&#8217;ll need to assemble all the tools and materials needed to commence your PCB&#8217;s repair. <\/p>\n\n\n\n<p>Second, remove any damaged component using a sharp knife or flathead screwdriver.
