Circuit board repair is a relatively niche technical skill. An experienced repair engineer may need years or even decades of experience and continuous learning to achieve success. This article mainly shares some insights on circuit board repair. A circuit board consists of a circuit board, components, and software. I personally believe that the capabilities of … Read more
2. Characteristics and Identification of Resistor Damage Many beginners often struggle with resistors when troubleshooting circuits, taking them apart and re-soldering them. In fact, after gaining some experience, understanding the characteristics of resistor damage can save a lot of unnecessary effort. Resistors are the most numerous components in electrical devices, but they are not the … Read more
Successful RF design requires careful attention to every step and detail throughout the design process. This means thorough and careful planning must be done at the start of the design phase, along with comprehensive and continuous evaluation of the progress of each design step. Such meticulous design skills are often lacking in the culture of … Read more
With the rapid development of electronic products, there are many types of circuit boards, including hard boards, soft boards, and rigid-flex boards. Hard boards are ordinary PCB boards that cannot be bent; the vast majority of products use hard boards. Soft boards are flexible boards (FPC), which can be bent to a certain extent and … Read more
1. Observation Method When we receive a circuit board for repair, the first step is to carefully observe its appearance. If the circuit board has been burned, it is crucial to check whether the power circuit is functioning correctly before powering it up, ensuring that no further damage will occur. The observation method is a … Read more
When it comes to circuit boards, many people should be familiar with them, as they are ubiquitous in our lives, from small devices like Bluetooth headsets, electronic watches, and calculators to larger systems like computers, communication devices, and military/aerospace systems. Wherever integrated circuits are needed, they rely on PCB to carry electronic components. Before PCB … Read more
1 Tools for Manual Soldering Any electronic product, from a rectifier composed of several parts to a computer system made up of thousands of components, is constructed from basic electronic components and functions, connected using certain manufacturing methods according to circuit principles.Although there are various connection methods (such as winding, crimping, gluing, etc.), the most … Read more
In the process of circuit design, application engineers often overlook PCB layout. The common issues encountered are that the circuit schematic is correct, but it does not function properly or only operates at low performance… Have you faced this too? Today, I share an article by TI application engineer Timothy Claycomb on how to properly … Read more
PCB Manufacturing Process The manufacturing of PCBs is very complex. Taking a four-layer printed circuit board as an example, the main steps include PCB layout, core board manufacturing, inner layer PCB layout transfer, core board drilling and inspection, lamination, drilling, copper plating of the hole walls, outer layer PCB layout transfer, and outer layer PCB … Read more
PCB grounding is a concern for PCB layout engineers, such as how to effectively plan a grounding system on the board, whether to wire analog, digital, and power grounds separately or together at a single point, and how to eliminate ground loops on the circuit board. Today, we will mainly discuss PCB grounding design, PCB … Read more
