That is no longer true. Modern embedded processors, communication interfaces, industrial controllers, and even consumer electronics now carry signals that switch fast enough to behave like transmission lines rather than simple copper connections.<\/p><p>The real dividing line is not only clock frequency.

High-speed traces also need to stay away from unrelated structures and circuits that can inject noise or create discontinuities.<\/p><p>Probe points and test pads should not be placed directly on a high-speed differential pair. A test point creates a stub, and a stub is exactly the kind of discontinuity that can cause reflections at high-speed frequencies.<\/p><p>For the same reason, high-speed traces should avoid routing under or near:<\/p><ul><li>Crystals<\/li><li>Oscillators<\/li><li>Clock generators<\/li><li>Switching regulators<\/li><li>Magnetic components<\/li><li>Mounting holes<\/li><li>ICs that generate or distribute clock signals<\/li><\/ul><p>These areas can introduce electromagnetic noise or disturb the local return path. A high-speed trace routed nearby can easily pick up that interference.<\/p><p>The area around the main chip package deserves special attention. Immediately after a BGA breakout, high-speed pairs should remain clear of the SoC package for slightly longer than a normal low-speed route would require.

That means the pair should be routed in parallel, with consistent spacing and symmetrical geometry for as much of the run as possible.<\/p><p>Some deviation is unavoidable. BGA breakout regions and connector approaches rarely allow perfect parallel routing. However, these non-parallel sections should be kept as short as possible. As a practical guideline, breakout routing from the device package should be completed within about 0.25 inches of the part.<\/p><p>Beyond that distance, small asymmetries can begin to create measurable skew between the two halves of the pair.<\/p><p>Connector type also affects routing strategy.<\/p><p>For through-hole connectors such as a standard USB Type-A connector, high-speed pairs are often routed on the bottom layer. The through-hole pins themselves can act as stubs through the PCB, and bottom-side routing helps keep the signal path shorter and cleaner.<\/p><p>For surface-mount connectors such as USB Micro-B or Micro-AB, the opposite is usually preferred. Routing on the top layer allows the signal to reach the connector without an additional via transition.<\/p><p>The goal is the same in both cases: minimize the number of discontinuities the signal must pass through before leaving the board.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4047acd wd-width-100 elementor-widget elementor-widget-wd_title\" data-id=\"4047acd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wd_title.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"title-wrapper wd-set-mb reset-last-child wd-title-color-primary wd-title-style-underlined wd-title-size-large text-left\">\n\n\t\t\t\n\t\t\t<div class=\"liner-continer\">\n\t\t\t\t<h2 class=\"woodmart-title-container title wd-fontsize-xxl\">Treat Vias and SMD Pads as Discontinuities<\/h2> \n\t\t\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4bfbbee color-scheme-inherit text-left elementor-widget elementor-widget-text-editor\" data-id=\"4bfbbee\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Every via is not just a connection between layers. It is a localized change in geometry, and at high-speed frequencies that geometry change behaves as both a capacitive and inductive discontinuity.<\/p><p>When a high-speed signal changes layers, its return current must also move between the corresponding reference planes. To keep that vertical return path short and low impedance, ground stitching vias should be placed close to the signal vias.<\/p><p>The most damaging part of a via is often the unused portion of the barrel. For example, if a signal moves from an outer layer to an inner layer, the remaining unused via barrel below that transition becomes a stub. That stub can behave like a small resonant structure.<\/p><p>Longer stubs resonate at lower frequencies and can increase insertion loss. In many high-speed designs, the unused via stub can degrade the signal more than the actual layer transition itself. This is why backdrilling is commonly used on faster interfaces to remove unused via barrel length.<\/p><p>SMD components placed directly in a high-speed signal path create a smaller version of the same problem. Sometimes they are necessary, such as AC coupling capacitors on high-speed interfaces. When they are required, package size matters.<\/p><p>As a general rule, 0603 should be treated as the largest acceptable size, while 0402 or smaller is preferred. Smaller packages introduce smaller discontinuities.<\/p><p>These components should also be placed symmetrically on both halves of the differential pair. If one capacitor is placed ahead of the other, the layout reintroduces skew even if the rest of the routing is carefully matched.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6c5126f wd-width-100 elementor-widget elementor-widget-wd_title\" data-id=\"6c5126f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"wd_title.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"title-wrapper wd-set-mb reset-last-child wd-title-color-primary wd-title-style-underlined wd-title-size-large text-left\">\n\n\t\t\t\n\t\t\t<div class=\"liner-continer\">\n\t\t\t\t<h2 class=\"woodmart-title-container title wd-fontsize-xxl\">Avoid Sharp Bends<\/h2> \n\t\t\t\t\t\t\t<\/div>\n\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-867c4bd color-scheme-inherit text-left elementor-widget elementor-widget-text-editor\" data-id=\"867c4bd\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>In an ideal layout, a high-speed differential pair would not bend at all.

The 5W spacing rule cannot fix a broken reference plane. A good stackup cannot compensate for long via stubs. Perfect trace width control will not save a route that passes too close to a clock source or switching regulator.<\/p>\n<p>That is why early engineering review matters. <a href=\"https:\/\/pcbcool.com\/es\/\">PCBCool<\/a> supports high-speed PCB projects where stackup planning, controlled impedance, fabrication capability, and assembly reliability need to be considered before the board is built.
