Today, of course, engineers can be dealing with as much as 25Gbps. While we are pushing for faster rates, we are also parallelly making smaller devices given the trend of miniaturization.<\/p>\n<p>With high speed also come a number of challenges, primary among them being interference. In fact the faster the data rates, the harder it can get to protect the integrity of signals.<\/p>\n<p>Making your <a href=\"https:\/\/www.technotronix.us\/pcbblog\/how-to-speed-up-the-pcb-production-time-using-smt-pcbs\/\">high-speed board design<\/a> project success, therefore, involves paying attention to a number of factors.<\/p>\n<h2 style=\"margin-bottom: 18px;\">Here are some of the aspects to watch out for High-Speed Board Design:<\/h2>\n<h3>Have a plan in place<\/h3>\n<p>This might sound like an obvious thing to do, but the fact remains that without a proper plan in place you are likely to suffer a whole lot of setbacks. The plan needs to include aspects such as:<\/p>\n<ul style=\"padding-left: 25px; list-style-type: disc; margin-bottom: 20px;\">\n<li>Having a visual diagram for the sub-circuits and return current.<\/li>\n<li>Knowing the frequency and fastest rise time of each signal.<\/li>\n<li>Having a plan to meet requirements for differential signals, controlled impedance and more.<\/li>\n<li>Documenting voltage and power requirements.<\/li>\n<\/ul>\n<h3>Document details of your board stackup<\/h3>\n<p>It is important to determine which material you will be using for the board and what are the specific constraints that need to be followed in terms of the design rules. FR4, for example, works well when you are working with speeds &lt; 5Gbps. When it comes to between 5-25 Gbps clock speeds, Nelco, SI or Megtron work well. For high-speed designs, Rogers as a material is known to work well. Once the <a href=\"https:\/\/www.technotronix.us\/pcb-material-management.html\">PCB material<\/a> has been chosen, layer stackup strategies need to be kept in mind. Some of these include:<\/p>\n<ul style=\"padding-left: 25px; list-style-type: disc; margin-bottom: 20px;\">\n<li>Placing a signal layer adjacent to a plane layer<\/li>\n<li>Routing high-speed signals on the inner layers of the board<\/li>\n<li>Using multiple ground planes to lower reference impedance.<\/li>\n<\/ul>\n<h3>Power and Ground Planes<\/h3>\n<p>The ground plane should not be split with any routed signals. Split it can lead to EMI and signal timing issues. In case a ground plane has to be split, a 0 Ohm resistor needs to be added.<\/p>\n<h3>Keeping size of land patterns minimum<\/h3>\n<p>With high-speed designs since the board real estate is at a premium, you need to save space. To this end, the minimum oversize of the pads should be kept at 0-5% of the size of the component pins. Also, the less the space given to vias, the more room there is for differential pairs, vias and more.<\/p>\n<h3>Route Signals for Maximum Shielding Benefits<\/h3>\n<p>To ensure that signals do not interfere with each other or with any component, some of the guidelines to be followed include:<\/p>\n<ul style=\"padding-left: 25px; list-style-type: disc; margin-bottom: 20px;\">\n<li>Ensure you do not keep long, parallel signals<\/li>\n<li>Maintain distance between signal traces<\/li>\n<li>Route signals orthogonally<\/li>\n<\/ul>\n<h3>Path for Current Return<\/h3>\n<p>Using vias to return currents to their termination is recommended. Ensure also that the vias are impedance matched, differential vias. Return vias also need to be placed close to signal vias.<\/p>\n<h3>3W Rule<\/h3>\n<p>The 3W rule comes in handy to minimize coupling. The rule states that the separation between traces must be equal to three times the width of a single trace from center to center.<\/p>\n<h3>20H Rule<\/h3>\n<p>To prevent coupling between power and ground planes, it is advisable to sue the 20H rule. It states that the power plan must be made 20 times smaller than the dielectric thickness between adjacent power &amp; ground planes.<\/p>\n<h3>General Routing Guidelines<\/h3>\n<p>When it comes to routing guidelines, the following tips will come in handy:<\/p>\n<ul style=\"padding-left: 25px; list-style-type: disc; margin-bottom: 20px;\">\n<li>Avoiding 90-degree angle bends in your traces.<\/li>\n<li>Length match tuning in the <a href=\"https:\/\/www.technotronix.us\/pcb-layout.html\">PCB design<\/a> software is necessary.<\/li>\n<li>Designing transmission lines with the use of microstrip or stripline traces is imperative.<\/li>\n<\/ul>\n<h2>To sum up<\/h2>\n<p>Overall arming yourself with strategies and knowledge to combat issues such as interference can go a long way in maintaining integrity of signals.
