Do you know what high-frequency PCB is ? What applications are high-frequency PCB used for? Today, the editor of United Multilayer will show you what high-frequency PCB is and in what fields it is used. High-frequency PCB is a special circuit board with a higher electromagnetic frequency, which is above 1GHz. The physical properties, precision and technical...
24GHz radar detection system mainly supports short-range detection (SRR), high frequency circuit board and high wavelength. Applicable boards: RO4835, RO4350B, RO4003C . Among them, RO4350B nitride ceramic laminate and RO4835 nitride ceramic laminate are highly recommended. These two series belong to the cost-effective series for people’s daily use. Its PCB production cost is low, and it has...
PCB physical object: A double-layer board has copper foil conductors on both sides. Electronic version PCB: There are two colors of conductors (different colors of conductors represent different layers) 3 Double-layer PCB board design and wiring principles The ground wire of the double-layer board is designed to be formed as a grid-shaped frame, that is, more parallel ground wires are laid...

Software Rule Settings To begin with, enter Design > Rules and adjust the options based on design requirements: Safety Spacing Settings: In PROTEL99SE, the Clearance Constraint under Routing defines the necessary spacing between traces, pads, and vias of different networks. Single/Double-sided boards: Set spacing to 10-12mil. Multi-layer boards (four layers or more): Set spacing to 6-8mil. Routing Layer and Direction: Go to Routing Layers under Routing and set...
In circuit board manufacturing, various electroplating methods are employed to enhance performance, durability, and contact quality. This article focuses on four specialized electroplating methods commonly used in PCB (printed circuit board) welding processes. 1. Finger-Ring Electroplating Finger-ring electroplating involves plating rare metals, such as gold, on the edge connectors or gold fingers of circuit boards to provide low...
In circuit design, there are often principles that engineers assume to be correct, but in reality, they may lead to issues in performance or efficiency. Here are eight common circuit design misunderstandings every electronics engineer should be aware of: Misunderstanding 1: Thin Wires and Automatic Routing Are Good Enough for Low-Requirement PCB Design Comment: While automatic routing might...
Open circuits and short circuits are common issues that PCB manufacturers encounter, often leading to shipment delays, customer complaints, and costly production interruptions. With over 20 years of experience in the PCB manufacturing industry—covering production, quality management, process optimization, and cost control—I have gathered valuable insights into addressing these challenges. Below is a summary of the main causes of PCB...
After years of experience in PCB design, certain best practices have emerged. Here, we outline essential aspects of PCB layout, wiring, copper plating, and more, with a focus on optimizing performance and manufacturability. 1. Layout and Wiring Impact on Electrical Performance Separate Digital and Analog Ground: Although challenging, separating these can reduce noise. Understanding IC electrical...
Grounding is fundamental in electronic PCB circuit design, influencing stability, noise immunity, and overall performance. Grounding techniques range from basic single-loop analog grounding to advanced grounding methods for complex mixed-signal designs. These techniques become increasingly critical in high-frequency or high-EMC (Electromagnetic Compatibility) environments. Here’s a comprehensive overview of grounding techniques and methods for reducing ground loops to enhance...
