Introduction to Intel's PCB Tabbed Routing Technology and Solutions

Image
1. What is Tabbed Routing Tabbed Routing is an innovative PCB routing method invented by Intel, targeting the limited PCB routing area, which cannot meet the normal transmission line width and spacing requirements between lines, thus generating impedance mismatch and signal crosstalk. Tabbed Routing can be applied to any bus in theory, but based on the wiring characteristics of various buses, DDR bus is the main application scenario at present. Tabbed Routing can be applied to any bus in theory, but based on the wiring characteristics of various buses, DDR is the main application scenario. 2. Why use Tabbed Routing? To answer this question, you need to understand the cabling characteristics of the DDR bus and a few key concepts: Pin Field, Breakout, Open Field, etc. Intel PDG uses these terms to describe different cabling areas, of course, there are terms to describe other areas, but this article only discusses Tabbed Routing-related applications, which involve the following three part

PCB Design for Power Module

Image
PCB Design for Power Modules The power circuit is a crucial component of an electronic product, directly influencing its performance. Linear and high-frequency switching power circuits are commonly used, each with distinct characteristics. Linear power supplies deliver current proportional to the load, while switching power supplies provide power as required by the load. Linear Power Supply Linear power supplies employ devices such as voltage regulators (e.g., LM7805, LM317, SPX1117) operating in a linear state. The schematic of an LM7805 voltage regulator is illustrated below. In linear power supplies, rectification, filtering, voltage regulation, and energy storage components are utilized. Typically, series voltage regulators are used, where the output current equals the input current (I1 = I2 + I3). Understanding current flow and magnitude is crucial in PCB design, as trace width is determined based on current requirements between component nodes (refer to " PCB Design Copper
