In the development of electronic products, PCB (Printed Circuit Board) design plays a critical role. A well-designed PCB not only ensures the stable and efficient operation of the circuit but also helps reduce production costs and improve product reliability. For designers, mastering the basic characteristics of excellent PCB design is
High-Density Interconnect (HDI) PCBs offer higher component density and better performance, but designing them comes with unique challenges. Issues like signal integrity, thermal management, and manufacturing complexity can make HDI PCB design difficult.
This article explores the common problems faced in HDI PCB design and offers practical strategies to improve performance,
Surface Mount Technology (SMT) is the dominant method for assembling printed circuit boards (PCBs) in modern electronics. The design process of a Surface Mount PCB involves several stages, from creating an initial schematic to the final product assembly. Each step plays a crucial role in ensuring the board’s performance, reliability,
In the world of electronics, PCB design (Printed Circuit Board design) is one of the most critical processes, serving as the foundation for building electronic devices. Whether you are a beginner trying to learn the basics or an experienced professional aiming to refine your skills, understanding the PCB design process
How to choose how many layers of boards are used for design and how to stack them, Today we are going to talk about this topic.
The following are some common stacked structures, let's analyze them：
PCB Layer stackup of single-sided and double-sided boards
For two-layer boards, there is no stacking problem due to
When the PCB design is completed, the laminate layer is determined, and the PCB board has been put into fabrication, the simulation evaluation found that the high-speed signal channel margin may be unsafe. Is there still a chance to improve?
Let's first introduce the loss classification of PCB. There are three
Design requirements for PCB：
PCB design shoud be right
This is the most basic and important requirement of PCB design. It is necessary to accurately connect the electrical schematic diagram and avoid the two simple and fatal errors of "short circuit" and "open circuit". This basic requirement is not easy to do
PCB design mistake 1: Overlap of weld pad
The overlap of the pad (except for surface welding) means the overlap of holes. In drilling process, drill holes will be broken due to multiple drill holes, resulting in damage to holes.
The two holes in the multi-layer plate overlap, such as one
When we design PCB, it’s necessary consider how to calculate PCB trace width/space for the through current.so what is the relationship between PCB trace width and space and current? The following is a brief explanation of this:
The PCB trace width/space and current calculation method is as follows:
Calculate PCB trace area
The thickness of the copper foil for most of the PCBcircuit
What kind of documents is needed for the PCB factory to make the board?
As PCB design is confidential, so PCB gerber file which is unified industry standard file is required, PCB factory can use CAM software input PCB gerbr file.
Mechanism diagram: long width thickness and its tolerance requirements,
