The manufacturing process of PCB (printed circuit board) using resin film products has unique technical characteristics and advantages, which is worth in-depth discussion. Resin film is a functional material, usually made of polyimide (PI), polyester (PET) or other synthetic resins. The excellent properties of these materials make PCB widely used in modern electronic devices. First,…
The frequency of electronic signals and processors of electronic equipment is constantly increasing, and the electronic system has become a complex device containing multiple components and many subsystems. High density and high speed will increase the radiation of the system, while low voltage and high sensitivity will reduce the anti-interference of the system. Therefore, electromagnetic…
Introduction to Creepage Distance In printed circuit board (PCB) design, creepage distance represents a critical safety parameter that determines the shortest path between two conductive parts along the surface of the insulating material. This concept plays a fundamental role in ensuring electrical safety and preventing potential failures in electronic devices. Creepage distance differs from clearance…
How to manually add a network to a PCB in Altium? A: As shown in Figure 1, many old Protel engineers are generally accustomed to drawing wire strips without a network directly in the PCB for PCB design. Often, only the design engineer himself is clear about the connection relationship, which will cause considerable trouble…
Introduction Power integrity is a critical aspect of printed circuit board (PCB) design, directly impacting the performance, stability, and reliability of electronic systems. A well-designed power distribution network (PDN) ensures stable voltage levels, minimizes noise, and reduces electromagnetic interference (EMI). Among the key elements of PDN design, the power plane plays a vital role in…
Printed Circuit Boards (PCBs) form the foundation of nearly all modern electronic devices, from smartphones to industrial equipment. The quality of a PCB directly impacts the performance, reliability, and longevity of the final product. For engineers, procurement specialists, and quality control professionals, the ability to quickly assess PCB quality is an invaluable skill. This 2000-word…
If the wiring does not require an extra layer, why use it? Wouldn’t reducing the layer make the board thinner? Wouldn’t the cost be lower if the board had one less layer? However, in some cases, adding a layer can reduce costs. PCB boards have two different structures: core structure and foil structure. In the…
Abstract This paper explores the critical considerations in designing printed circuit boards (PCBs) for high-speed digital circuits. As digital systems continue to operate at higher frequencies with faster edge rates, traditional PCB design approaches become inadequate. This article examines signal integrity, power integrity, electromagnetic compatibility, material selection, and layout techniques essential for successful high-speed digital…
Introduction In printed circuit board (PCB) design, power delivery is a critical aspect that directly impacts the performance, reliability, and efficiency of electronic devices. Power traces must be designed to handle the required current without excessive voltage drop, overheating, or signal integrity issues. One of the most effective ways to ensure robust power distribution is…
Introduction Printed Circuit Boards (PCBs) are essential components in modern electronics, and the soldering process is crucial for assembling components onto them. During soldering, flux is used to remove oxides, improve wetting, and ensure reliable solder joints. However, flux residues left on PCBs can cause corrosion, electrical leakage, and reduced performance if not properly cleaned….
Recently years that self-driving cars were introduced to the public, rockets were re-landed from space with fine-tuned precision for reuse, and Moore’s Law continued on its endless trajectory of growth. However, one thing missing from all of these technological advances is a good autorouter. The Real Problem with Autorouters Although PCB autorouters have been around…
As we all know, the basic properties of PCB (printed circuit board) depend on the performance of its substrate material. Therefore, in order to improve the performance of the circuit board, the performance of the substrate material must be optimized first. So far, various new materials are being developed and applied to meet the requirements…
In the 7th century BC, Greek soldiers or heavy infantry carried a large concave circular shield called a hoplon. Made of bronze and wood, the hoplon or Argive shield protected the heavy waist from chin to knees and when overlapped became the basis of the Greek phalanx. In the early 20th century, Ethiopians fought against…
Abstract In printed circuit board (PCB) design, teardrops are small, tapered connections between pads and traces or vias and traces that enhance reliability and manufacturability. This article explores the significance of teardrops in PCB design, their benefits, and various methods to add them using modern electronic design automation (EDA) tools. 1. Introduction PCB design involves…
Electromagnetic compatibility (EMC) and the associated electromagnetic interference (EMI) have always required system design engineers to keep their eyes open. In today’s situation where circuit board designs and component packages are constantly shrinking and OEMs are demanding higher-speed systems, these two major issues are particularly headaches for PCB layout and design engineers. EMC is closely…
