Introduction PCB manufacturing has undergone significant transformations over the past few decades. As the backbone of modern electronics, PCB manufacturing must continuously evolve to meet the demands of new technologies and applications. This article explores the emerging trends in PCB manufacturing , bridging traditional methods with cutting-edge innovations. These advancements not only enhance the performance and reliability of PCBs but also address environmental concerns and improve production efficiency. The Evolution of Traditional PCB Manufacturing Traditional PCB manufacturing methods, such as subtractive processes (e.g., etching) and additive processes (e.g., plating), have been foundational in the industry. These techniques, while effective, face limitations in precision and material utilization. Subtractive processes, for example, can waste significant amounts of raw materials, and the chemical etching used can pose environmental hazards. In contrast, additive processes a...

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 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 ...

Circuit boards are an indispensable part of electronic products, and the components on them are their basic building blocks. For beginners or those interested in electronics, it is essential to recognize and understand the components on a circuit board. In the following, we will introduce the types of components, marking and identification methods in detail. I. Types of Components There are a wide variety of components on a circuit board, but they can be divided into the following main categories: Resistors : Components used to limit current, usually to divide voltage or limit current. Resistors are usually indicated on the circuit board by a color ring or a number to indicate their resistance value. Capacitors : Used to store electrical energy and can play a role in the circuit such as filtering and coupling. Capacitors on the circuit board usually include capacity value, withstand voltage value. Inductors: mainly used for filtering, oscillation, delay, trapping and other circuits, co...
