in the general news media as they relate to printed circuit board technology.
As experts in the manufacture and assembly of printed circuit boards, we work to make our blog a helpful resource on PCB topics and the industries that we work with, including automotive, consumer electronics, aerospace and many more.
The advantage of Protel is that it is more popular in the Chinese market. As long as the PCB is Protel, any file can make a board. Southern China is more likely to accept the OrCAD format.
As data rates continue to increase, signal integrity issues have become the most critical factor for design engineers to consider. This exponential increase in data rate can be seen in applications such as handheld mobile devices and consumer display products to high-bandwidth routers/switches. Jitter (noise) is the primary reason for reducing the level of signal integrity in a design. In addition to signal integrity enhancement techniques using layout, impedance matching, and more expensive materials, designers can simply add jitter cancellers such as equalizers to the design to solve jitter problems. This way designers don't have to focus on signal integrity issues, but focus on the core design of the system.
Learn how to reduce signal interference and optimize your high-speed PCB design with crosstalk analysis techniques. Discover practical tips and insights in this comprehensive guide.
In design, layout is an important part. The quality of the layout results will directly affect the effect of the wiring, so it can be considered that a reasonable layout is the first step in the success of PCB design.
1-50 POINTS
4 methods and solutions
Reasonable layout of components is the basic premise for designing high quality PCB drawings. The requirements for component layout mainly include installation, stress, heat, signal and aesthetic requirements.
1. 3 points above the connection, as far as possible through the line in order to facilitate testing, the length of the line as short as possible.
The below describes several EDA software commonly used in circuit design. There are many EDA softwares in this industry, such as transformer design, electrical design, integrated circuit design, etc., as well as a variety of microcontrollers. Simulation software.
PCB design tools have grown steadily in recent years to address the challenges of this increasingly complex design landscape. A major change – the adoption of 3D capabilities, is expected to allow designers to balance design innovation with the competitiveness of the global marketplace.
1. Right angle line (three aspects) 2. Differential traces ("equal length, equidistant, reference plane") 3. The snake line (adjustment delay)
In SoC design, the coupling between signals can cause signal integrity problems. Neglecting signal integrity problems can lead to crosstalk between signals. Reliability, manufacturability and system performance will also be reduced. This article describes the design of ASIC chips. A method for solving signal integrity problems.
The PROTEL99 electrical layer is divided into two types, the positive layer and the negative layer. These two layers have completely different properties and usage methods.
In the PCB layout, the handling of the power and ground wires is very important. The noise interference generated by the power cables and ground wires should be minimized to ensure the quality of the products.
PowerPCB enables users to achieve high-quality design and vividly reflects all aspects of the electronics design industry. Its constraint-driven design approach reduces product completion time. You can define safety spacing, routing rules, and design rules for high-speed circuits for each signal, and apply these plans hierarchically to the board, to each layer, to each type of network, to each network, to each group. On the network, each pin is placed to ensure the correctness of the layout design. It includes a wide range of features including clustering tools, dynamic routing editing, dynamic electrical performance checks, automatic dimensioning and powerful CAM output capabilities. It also has the ability to integrate third-party software tools such as the SPECCTRA router.
The moisture sensitivity of plastic integrated circuits (ICs) is getting worse and worse, due to many industry trends, including the constant search for higher reliability products to support critical communications and technology applications.
Build up Multilayer PCB, BUM refers to the application of insulating dielectric on the insulating substrate, or the traditional double-panel or multi-layer board, and then electroless copper plating and electroplating copper to form wires and connecting holes. A multilayer printed board requiring a number of layers.
