In the field of electronic design, the PCB selection guide is a core tool for engineers to avoid design risks and optimize product costs. A suitable circuit board, like a solid foundation, directly determines the performance, reliability, and market competitiveness of the final product. This guide aims to provide a systematic PCB selection framework to … Read more
In the hardware design of LCD screens and related LCD modules, precise configuration of timing parameters is fundamental to achieving optimal display performance and system stability. Among these, PORCH (blanking interval) settings are particularly critical—they define the exact boundaries of the pixel clock (PCLK), horizontal/vertical sync signals (Hsync/Vsync), front/back porches (HBP/HFP, VBP/VFP), and the active … Read more
Definition and Core Concepts of Waveform Capture Rate The Waveform Capture Rate is a key performance indicator of digital oscilloscopes, representing the number of times the oscilloscope can capture and display waveforms within a unit of time, typically measured in “captures per second” or “frames per second.” Its core significance lies in reflecting the oscilloscope’s … Read more
Editor’s Note: This article is excerpted from a presentation titled Novel Surface Finish for 5G-mmWave Frequency PCB Technologies: How to Achieve Optimum Signal Integrity. 0 Introduction With the increasing demand for high-frequency electronic devices, the shortcomings of traditional surface treatment processes such as electroless nickel immersion gold (ENIG) on printed circuit boards (PCBs) have become … Read more
When a PCB board has completed its layout and routing, and there are no errors reported in connectivity and spacing, does that mean the PCB is finished? The answer is certainly no. Many beginners, as well as some experienced engineers, often rush through the process due to time constraints, impatience, or overconfidence, neglecting the post-design … Read more
The MIPI (Mobile Industry Processor Interface) interface, especially its physical layers D-PHY and C-PHY, is widely used in high-speed data transmission scenarios such as cameras (CSI-2) and displays (DSI-2). The PCB layout and routing of MIPI are crucial for signal integrity, directly affecting the performance and reliability of devices. Below are key guidelines for MIPI … Read more
The manufacturing of circuit boards in the electronics industry is crucial. Traditional manufacturing methods cannot visually detect issues related to heat, thermal flow (heat & high-speed electronic particles & interference particles, etc.), impedance, load, and more. With the development of smart technologies, many new techniques and devices have addressed previous shortcomings, such as using sensors … Read more

First, we need to ask, what is signal integrity? Why do we perform signal integrity analysis? How do we conduct signal integrity analysis? What do we achieve after signal integrity analysis?Let’s first discuss,what is signal integrity?Signal Integrity (SI): It refers to the ability of a signal to be transmitted and switched in a circuit with … Read more
Recently, I encountered a customer complaint regarding PCBA blind and buried via issues. I took this opportunity to study the topic and share knowledge with my colleagues and friends. **Core Concept:** In traditional PCB design, vias (referred to as “through holes” or “vias”) that connect different layers of circuits are through holes that extend from … Read more
