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

“Right-angle traces should be avoided in PCB design.” I believe most PCB beginners and engineers know this requirement. But is it true that the traces on the PCB cannot go at 90° corners? Is the impact really that terrible? Today, we might as well talk about this topic together. Can

The power circuit is an important part of an electronic product. The quality of the power circuit design will directly affect the performance of the product. Next, 2PCB will share with you some engineers’ experience summaries on power supply PCB design, hoping it will be helpful to everyone. Basic principles

The types of wiring on the PCB mainly include signal lines, power supply, and ground wires. Among them, signal lines are the most common wiring, and there are many types. According to the physical structure of the wiring, it can be divided into strip lines and microstrip lines. Stripline A

PCB novices will always encounter various “pits” at the beginning, such as common spacing issues: the spacing between wires, the spacing between pads, etc. In this article, 2PCB will talk to you about the safety spacing issue in PCB design. Electrical safety distance 1. Spacing between wires This spacing needs

A big boss in the PCB design industry said: A qualified PCB design engineer must not only have rich circuit design experience, but also have knowledge and experience in production and manufacturing. Design that is divorced from actual production is nothing more than talking on paper. Today, we might as

(AutomatedVisualInspection) is an efficient and accurate automated inspection equipment, specially used to inspect the appearance quality of PCB. It uses a vision system, image processing technology and artificial intelligence algorithms to conduct a comprehensive and accurate inspection of the PCB appearance to discover any possible defects or problems. Functions of

PCB boards always encounter various problems during the design and production process, such as PCB board short circuit, dark and granular contacts on the PCB board, board bending, etc. In this article, 2PCB and everyone will learn about some common causes of PCB board defects. PCB board short circuit This
