The following content of this article introduces the ten most effective design rules that electronic design engineers should keep in mind and practice when using design software for PCB layout design and commercial manufacturing. Engineers do not need to implement these laws in chronological order or relative importance; simply following them all can dramatically change…
Via is one of the important components of multi-layer PCB, and the cost of drilling usually accounts for 30% to 40% of the cost of PCB board manufacturing. Simply put, every hole on the PCB can be called a via. From the perspective of function, vias can be divided into two categories: one is used…
[First Trick] Multilayer Board Wiring High-frequency circuits are often highly integrated and have high wiring density. Using multilayer boards is not only necessary for wiring, but also an effective means to reduce interference. In the PCB Layout stage, a reasonable selection of the size of a printed circuit board with a certain number of layers…

1.What are electromagnetic interference (EMI) and electromagnetic compatibility (EMC)? (Electromagnetic Interference), there are two types of interference: conducted interference and radiated interference. Conducted interference refers to the coupling (interference) of a signal on an electrical network to another electrical network through a conductive medium. Radiated interference refers to the coupling (interference) of an interference source…
The threat of static electricity is everywhere, and the electrostatic protection of electronic components is very important During the SMT processing, electrostatic discharge can cause damage or failure to electronic components. With the increase in IC integration and the gradual reduction of components, the impact of static electricity has become more serious. According to statistics,…
In PCBA production, it is often easy to tackling tin at the tail end of the device. In order to avoid this defect in production, a pair of pads without electrical properties need to be added to the tail of the device during design, which is the tin-stealing pad. Its function is to guide the…

Engineers have all come into contact with impedance, but few engineers can explain impedance clearly. Impedance seems simple, but it is actually difficult to express.Below we use a quick question and answer method to help you understand impedance easily! 01 Q: What is impedance? A: In a circuit with resistance, inductance and capacitance, the obstruction…
In electronic devices, power modules are core components that convert input DC voltage into various DC voltages required by the device. DC-DC power converters, especially those based on switching mode, are widely used due to their high efficiency, small size and light weight. However, it is not easy to design an excellent DC-DC power converter….
Discover the factors influencing PCB manufacturing prices in this comprehensive guide. Learn how material selection, complexity, and production volume affect costs, helping you make informed decisions for your projects.
01 Introduction The resistivity of copper is determined by its crystal structure, void volume, grain boundaries and material interface mismatch, and increases significantly with size reduction. Typically, the manufacturing process of copper wires is to etch trench patterns in low-dielectric silicon dioxide using a trench etching process, and then fill the trenches with copper through…
Designing excellent PCBs requires not only innovative design concepts, but also a deep understanding of PCB processes. As a key link in PCB design, via design is crucial to the manufacture and performance of PCBs. In this article, we will analyze PCB via design to help electronic engineers complete hardware research and development more efficiently….
