PCB design is not a random matter. There are many specifications that designers need to comply with. The following are some commonly used PCB design specifications collected by 2PCB, which are worth learning. Basic principles of layout 1. Communicate with relevant personnel to meet special requirements in structure, SI, DFM,

High-speed PCB design needs to face many different fields and products, and the core design requirements of each field are different. For example, the data and communications fields require ultimate product performance, and consumer products stand out for their performance-price ratio; on the contrary, the military and industrial fields require

A person must have an overall view, and the same is true for PCB design. Before starting a PCB project, designers must understand the overall process of the entire project from start to finish, as well as some key points that require special attention during the operation of the project.

How to improve your PCB layout skills? A very important way is to see if you can ask questions and answer them. Alternatively, we can also grow from other people’s questions and answers. 1. I recently studied PCB design. For high-speed multi-layer PCB, what are the appropriate line width settings

The number of layers of PCB depends on the complexity of the circuit board. From the perspective of PCB processing, multi-layer PCB is manufactured by stacking and laminating multiple “double-sided PCBs”. However, the number of layers of multi-layer PCB, the order of stacking between layers and the selection of board

PCB design is not a simple task and requires both technical knowledge and design experience. As the saying goes, “You can see further by standing on the shoulders of your predecessors.” Similarly, as PCB design beginners, we can also avoid taking some detours by summarizing the experience of our predecessors.

Once the PCB design is completed, everything will be fine? In fact, this is not the case. Various problems are often encountered during PCB processing and manufacturing, such as tin connection after wave soldering. Of course, not all problems are caused by PCB design, but as designers, we must first

Wiring is an important part of PCB design, and it is also the most workload-intensive and time-consuming part of the entire PCB design. Engineers need to follow some basic rules when performing PCB wiring work, such as chamfering rules, 3W rules, etc. Ground loop rules The minimum loop rule means

What is encapsulation? Packaging refers to connecting the circuit pins on the silicon chip to external connectors with wires to connect them to other devices. Component packaging, simply put, is the appearance of the component, or the shape of the component on the PCB board. Only when the components’ packaging

During the PCB design process, some engineers do not want to lay copper on the surface and bottom of the entire board in order to save time. Is this right? Is it necessary for PCB to lay copper on the bottom layer of the surface? First of all, we need

Today, as signal rates continue to increase, high-speed PCB design has become an essential skill that every PCB engineer should pay attention to and master, including basic theoretical knowledge and practical design experience. Next, 2PCB will share with you some classic questions and answers about high-speed PCB design, which are

The principle of soldermask exposure Exposure is the core of the entire soldermask process. The principle of solder mask exposure mainly uses the scattering of light to produce an optical reaction with the photosensitive polymer contained in the solder mask film, thereby achieving the desired effect. Exposure is very critical
