We encounter various safety spacing issues in normal PCB design, such as the spacing between vias and pads, the spacing between traces, etc., which we should consider. We divide these spacings into two categories: Electrical safety distance Non-electrical safety distances 1. Electrical safety distance 1. Spacing between wires This spacing needs to consider the production…
What is ESD? What are its precautions? 1.ESD literally means electrostatic discharge. To put it simply, static electricity is a natural phenomenon that is usually generated through contact, friction, induction between electrical appliances, etc. It is characterized by long-term accumulation, high voltage (can produce several thousand or even tens of thousands of volts of static…
The advantage of the immersion gold process is that when printing circuits, the color deposited on the surface is very stable, the brightness is very good, the coating is very smooth, and the solderability is very good. The thickness of immersion gold is generally 1-3 Uinch, so the gold thickness produced by the surface treatment…
PCB circuit board is a substrate used to support and connect electronic components. It is made of insulating material and covered with copper foil on the surface and/or inside. Through the wires and electrical connections of copper foil, the PCB circuit board can realize functions such as signal transmission, power supply, and ground connection. So…
PCB proofing refers to the trial production of printed circuit boards before mass production. It is mainly used for electronic engineers to design circuits and complete the process of drawing PCBs before conducting small batch trial production to circuit board factories, which is PCB proofing. The following is an introduction to what preparations need to…
Introduction 1.Printed circuit board (PCB) is the basic support for circuit components and devices in electronic products. With the rapid development of electronic technology, embedded systems are used more and more widely. In many applications, people no longer consider function and performance, but reliability and compatibility. Printed circuit board (PCB) is the basic support for…
n an era of rapid technological advancement, electronic devices are everywhere, and the core components that support the normal operation of these devices—circuit boards—are carefully manufactured by professional circuit board factories. PCB, short for Printed Circuit Board, is an indispensable part of electronic equipment. It carries the connection and communication functions of electronic components. When you walk…
In PCB design, power supply is a topic that cannot be ignored, especially now that the power supply voltage of many products is getting lower and lower, and the current is getting higher and higher, often hundreds of amps, so now everyone is paying more and more attention to the integrity of the power supply….
following aspects: (1) Whether the distance between wires and wires, wires and component pads, wires and through holes, component pads and through holes, and through holes and through holes is reasonable and meets production requirements.(2) Are the widths of the power and ground wires appropriate, and are the power and ground wires tightly coupled (low…
Have you ever wondered how power is delivered within a complex PCB? Yes, it is a challenging job for PCB designers to design a power supply that provides the required power to each PCB component (IC, capacitor, etc.) because the power requirements of each of these components vary. Only a perfect power supply design can…
PCB design is a very critical part of electronic product manufacturing. Its quality is directly related to the performance and stability of the entire product. However, in the process of designing PCB, many people will make some common mistakes. If these mistakes cannot be corrected in time, they will greatly affect the product quality. This…
How to design a PCB board is not easy, but the right pcb design software can help a lot. Other engineers have spent some time learning the ropes of PCB design, and you can benefit from their experience. If you’re new to PCB design but still learning about designing custom circuit boards in Altium Designer®,…
Any item will be damaged due to continued use, especially electronic products.However, damaged items are not completely waste and can also be recycled.The same is true for PCBs. Moreover, with the advancement of science and technology, the number of electronic products has increased dramatically, which has shortened their service life. Many products are discarded without…
For circuit boards, it is not perfect once designed, but requires many tests before moving towards mass production. For engineers, troubleshooting circuit board problems is the most troublesome when something goes wrong. This article will share with you how to quickly troubleshoot circuit board problems? The circuit that used to be running normally suddenly became abnormal today. When the…
With the rapid development of mobile phones, electronics, communications and other industries, the PCB circuit board industry has also continued to grow rapidly. People have increasingly higher requirements for the number of layers, weight, precision, materials, colors and number of layers. reliability. Due to fierce market price competition, the cost of board materials is also rising. More…
