 When relying on printed circuit boards to achieve the desired functionality of a product, even a small error can lead to significant setbacks in your operation. That's why it's so crucial to address everything correctly at the first instance. Of course, this isn't always possible—but if you plan ahead and carefully avoid these mishaps, you're more likely to be 100% satisfied with the final outcome. Reasons for Common PCB Design Errors 1.Overly Complex Design: The PCB manufacturing process is already quite complex. Ideally, your PCB assembly factory would prefer to manufacture printed circuit boards in the most cost-effective manner. Overly complex designs can complicate this process and may actually put the functionality of the circuit board at risk. Collaborate with your PCB assembly partner to ensure that circuit boards are constructed in a simple and efficient manner, avoiding unnecessary delays and reducing costs. 2.Incorrect or Missing Gerber Files: Gerber files ...

 The welded residue on the PCB is mainly salt substances that are not completely volatile or reaction to the solder reactions during the welding process. These residues may have adverse effects on the performance and service life of PCB , so they need to be removed in time. Common welded residues include residues of rosin welds and residues of organic acid welds. The residue of the rosin welded is mainly composed of polymer pine fragrance, undesirable activation agent, and salt generated between the rosin and melting welded welded during welding. These substances swell after the moisture absorption, and some substances also respond to water with water. The residues of organic acid welds are mainly composed of a variety of organic acids, and also contain some compounds that can produce halogen ions at high temperatures. This type of residue is the most difficult to remove salt formed by organic acids and solder formation. They have strong adsorption properties and poor solubility. I...

 Battery management systems BMS basically vary in each project or execution. The reason is that you cannot follow a particular set of guidelines for this purpose. There are some prominent factors that make them vary all the time! Let’s see them below! How complex the battery pack you are using makes the battery management system different. Is it affordable or expensive? The pricing is also an important factor here! Is the battery you are using easy for your projects and applications?  Are there any safety concerns or application risks that you need to look for in this particular battery pack? Sometimes the authority guidelines and industry standards can also affect battery management systems. BMS varies in different applications.  We cannot ignore the two highly important features of the battery management system BMS at this point.

 Printing circuit board (PCB) is the basis of most electronic products. The PCB structure is simple. The most common connection of PCB is computer hardware. However, it is also used for radio, TV, mobile phone, etc. The performance of PCB depends on various factors, such as manufacturing materials, costs, manufacturing, prototypes, etc. In addition, PCB thickness also has a very important impact on the overall performance and durability, which affects the resistance and conductivity of PCB; therefore, it is necessary to work in perfect thickness. Whenever we talk about "standard" features or some projects, we talk about the characteristics of "standards" or some projects. When the benchmark is measured, we refer to the perfect feature we want to achieve. Therefore, our products have undergone and passed all performance, weight, durability, reliability and the most important quality testing. PCB slices: PCB sheets do not have a fixed standard thickness measurement va...

 In PCB board design, circuit design is the most basic for engineers. However, many engineers often be cautious when designing with complex and difficult PCB boards, but ignore some places to pay attention to when the basic PCB board design, which leads to errors. It can cause a perfect circuit diagram to have problems when converted into a PCB board or break completely. Therefore, in order to help engineers reduce design changes in PCB board design and improve work efficiency, several aspects should be paid attention to during the PCB board design process. 1. Make physical border The closed physical boundary is important for future component layout and wiring, and it must be accurate, otherwise installation problems will occur in the future. In the corner, it is best to use the arc. On the one hand, it can avoid scratching workers with sharp corners, and at the same time, it can reduce the stress effect. 2 component layout The layout of components has a great impact on the qualit...

 The overlapping layer refers to a collection of copper layers and PCB insulating layers before finalizing the circuit board design. It is necessary to be compact electronic products, which is why the PCB layer stacked in the electronics field is crucial. In order to make electronic products have a compact design, designers believe that PCBs containing a multi-layered design and 3D appearance need to be installed. Multi-layers help improve the board's ability to distribute energy, high-speed support signals, eliminate electromagnetic interference, and minimize cross-interference. Why do I need to perform the PCB layer? 1. Continuous development As the current technology is becoming more and more developed, the requirements of electronic products have become higher and higher. I hope PCB is small and light, and also hope to have better functionality and reliability and longer life. This will lead to multilayer PCBs. Stack two or more single-sided and/or double-sided PCBs together, a...
