The process of testing PCB circuit boards is a critical step in the manufacturing and assembly of electronic devices. It involves a series of meticulously designed evaluations and assessments to confirm that the PCB functions as intended and is free from defects. These tests not only assure the quality of the final product but also play a crucial role in identifying and rectifying issues early in the production process.
With the rapid development of electronic design technology and manufacturing technology, electronic products are gradually developing towards high density, high functionality, light,small, and high transmission rate; In addition, with the rapid development of chip miniaturization and the increase of the number of data transmission, the working frequency of the system is higher and higher, and…
When the PCB design is completed, the laminate layer is determined, and the PCB board has been put into fabrication, the simulation evaluation found that the high-speed signal channel margin may be unsafe. Is there still a chance to improve? Let’s first introduce the loss classification of PCB. There are three kinds of losses: conductor…
How to choose how many layers of boards are used for design and how to stack them, Today we are going to talk about this topic. The following are some common stacked structures, let’s analyze them： PCB Layer stackup of single-sided and double-sided boards For two-layer boards, there is no stacking problem due to the small…

Why Flexible Circuit Boards Experience Easy Soldering Failures – Understand the common issues and challenges related to soldering on flexible circuit boards. Explore the factors contributing to soldering failures on flexible PCBs and discover solutions to ensure successful soldering in your electronic projects.
Why PCB Thermal management is important? For electronic devices, a certain amount of heat will be generated during operation, so that the internal temperature of the device will rise rapidly. If the heat is not dissipated in time, the device will continue to heat up, and the device will fail due to overheating. performance will drop.Therefore, it is…
Solder defects often delay new product launches,What factors will affect the poor soldering of the circuit board? Solderability of circuit board holes affects soldering quality,The poor solderability of the circuit board holes in the PCB factory will cause virtual welding defects, which will affect the parameters of the components in the circuit, resulting in unstable conduction of…
High-frequency PCB and high-speed signal transmission lines should avoid routing at 90 degree corners, which is strongly required in various PCB Design Guides.Because the high-frequency and high-speed signal transmission line needs to keep the characteristic impedance consistent, and the 90 degree corner routing is used, the line width will change at the corner of the transmission…
