The control board is a core component in electronic devices, responsible for crucial functions such as instruction transmission, data processing, and logic control. Through built-in circuit boards and electronic components, it achieves precise control over the operational status of devices. With advancements in technology, the application fields of control boards are increasingly diverse. How should … Read more
In the field of electronic engineering, reverse engineering existing PCB boards is a common practice for many engineers or companies. This practice, known as “peeling apart,” is an important step for understanding circuit design, troubleshooting, or reproducing designs. So how can we efficiently peel apart a PCB board? 1. Record Component Information Carefully record the … Read more

Generally, based on the different reinforcing materials of the board, it can be divided into five categories: paper-based, glass fiber cloth-based, composite base (CEM series), laminated multilayer board base, and special material base (ceramic, metal core, etc.).If classified according to the different resin adhesives used in the board, common paper-based CCLs include: phenolic resin (XPc, … Read more
When starting to learn PCB design, it is often emphasized by experts to separate strong electricity and weak electricity. So what exactly are these two types of “electricity” and how can they be distinguished? 1. What Are Strong and Weak Electricity? Strong Electricity: Definition: Refers to alternating current or direct current greater than 2V (usually … Read more
1. Spacing Between SMD Components The spacing between SMD components is a crucial issue that engineers must pay attention to during layout. If the spacing is too small, it becomes very difficult to print solder paste and avoid solder bridging.The recommended distances are as follows: Spacing requirements for SMD components: Same type of components:≥0.3mm Different … Read more
With the continuous development of electronic science and technology, PCB technology has also undergone tremendous changes, and manufacturing processes need to progress as well. At the same time, the requirements for PCB circuit board processes in various industries have gradually increased. For example, circuit boards in mobile phones and computers use both gold and copper, … Read more
1. Considerations for Component Packaging in RF Circuits A successful RF design must pay careful attention to every step and detail throughout the design process, which means thorough and careful planning must be done from the start of the design phase, along with comprehensive and continuous evaluation of the progress of each design step. This … Read more
