PCB board development and demand
The basic characteristics of the printed circuit board depend on the performance of the substrate board. To improve the technical performance of the printed circuit board, the performance of the printed circuit substrate board must be improved first. In order to meet the needs of the development ...Read more -
Why do PCBs need to be made in Panel?
From PCBworld, 01 Why puzzle After the circuit board is designed, the SMT patch assembly line needs to be attached to the components. Each SMT processing factory will specify the most suitable size of the circuit board according to the processing requirements of the assembly line. F...Read more -
Faced with high-speed PCB, do you have these questions?
From PCB world, March, 19, 2021 When doing PCB design, we often encounter various problems, such as impedance matching, EMI rules, etc. This article has compiled some questions and answers related to high-speed PCBs for everyone, and I hope it will be helpful to everyone. 1. How to ...Read more -
Simple and practical PCB heat dissipation method
For electronic equipment, a certain amount of heat is generated during operation, so that the internal temperature of the equipment rises rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, and the device will fail due to overheating. The reliability of the ele...Read more -
Do you know the five major requirements of PCB processing and production?
1. PCB size [Background explanation] The size of PCB is limited by the capacity of electronic processing production line equipment. Therefore, the appropriate PCB size should be considered when designing the product system scheme. (1) The maximum PCB size that can be mounted on SMT equi...Read more -
How to decide whether to use single-layer or multi-layer PCB according to product requirements?
Before designing a printed circuit board, it is necessary to determine whether to use a single-layer or multi-layer PCB. Both design types are common. So which type is right for your project? What’s the difference? As the name implies, a single-layer board has only one layer of base materia...Read more -
Double-sided circuit board characteristics
The difference between single-sided circuit boards and double-sided circuit boards is the number of copper layers. Popular science: double-sided circuit boards have copper on both sides of the circuit board, which can be connected through vias. However, there is only one layer of copper on one si...Read more -
What kind of PCB can withstand a current of 100 A?
The usual PCB design current does not exceed 10 A, or even 5 A. Especially in household and consumer electronics, usually the continuous working current on the PCB does not exceed 2 A Method 1: Layout on PCB To figure out the over-current capability of the PCB, we first start with the PCB struc...Read more -
7 things you must know about high-speed circuit layout
01 Power layout related Digital circuits often require discontinuous currents, so inrush currents are generated for some high-speed devices. If the power trace is very long, the presence of inrush current will cause high-frequency noise, and this high-frequency noise will be introduced into othe...Read more -
Share 9 personal ESD protection measures
From the test results of different products, it is found that this ESD is a very important test: if the circuit board is not well designed, when static electricity is introduced, it will cause the product to crash or even damage the components. In the past, I only noticed that ESD would damage th...Read more -
Through hole drilling, electromagnetic shielding and laser sub-board technology of 5G antenna soft board
The 5G&6G antenna soft board is characterized by being able to carry high-frequency signal transmission and having good signal shielding ability to ensure that the internal signal of the antenna has less electromagnetic pollution to the external electromagnetic environment, and it can also en...Read more -
FPC hole metallization and copper foil surface cleaning process
Hole metallization-double-sided FPC manufacturing process The hole metallization of flexible printed boards is basically the same as that of rigid printed boards. In recent years, there has been a direct electroplating process that replaces electroless plating and adopts the technology of forming...Read more
