 The circuit board may be referred to as a printed circuit board or a printed circuit board. FPC circuit board is also known as flexible circuit board. Printing circuit board. Thin circuit board, printing (copper-engraving technology) circuit board, etc. The circuit board is the core component of electronic equipment. It is related to the operation of the entire device. So how does the printed circuit board work? Let's figure it out together. Working principle of printed circuit board The working principle of the circuit board is to use plate-based insulation material to isolate the surface conductivity layer of copper foil, so that current can flow along the pre-designed paths in various components, such as work, amplification, attenuation, modulation, demodulation, encoding, etc. Function. Composition of printed circuit boards The circuit board is mainly composed of pads, perforations, mounting holes, wires, components, connecting Watford circuit board SMT Patch Watford circuit b

 Automatic Optical Inspection (AOI) in the SMT patch is an automatic visual inspection made by a printed circuit board. Among them, the camera automatic scanning device has disaster faults (such as lack of components) and quality defects. Because it is a non-contact test method, it is often used in the manufacturing process. The high reliability of the Multi-CB multi-layer circuit board is guaranteed. It is particularly important for the following application areas: Line width illegal Illegal Excess copper Lack Short circuit high frequency High power load advantage The circuit board is produced after SMT is detected. According to its visual method, the AOI test can be used to detect many surface defects, such as opening, short circuit, error elements, missing components, etc. The following are the advantages of the AOI test: Multi-Test Object-AOI test is not only suitable for PCB, but also for PCB assembly. For PCB, inspection defects, such as short circuit, opening, and lack of welde

 1. Capacitor After the resistor, the capacitor may be the most common component on the circuit board, and the capacitor is also the first choice for PCB enthusiasts. However, there are fewer capacitors we use compared to resistors. The basic function of capacitors is to store charge in them. The capacitors include two metal plates. The two metal plates have electronics. The two panels store the opposite charge, while the electronics help separate them. In this way, the current begins to flow through the circuit. Capacitors have several classification methods. However, we mainly classify capacitors based on Capyats dielectric materials. This is because dielectric materials are responsible for giving the key characteristics of the capacitor; the denser the dielectric material, the more capacitors can be stored on its board; this is why we tend to use high-quality materials to make electric containers get higher. Capacitors . . Typical capacitors have two cables extending from the metal

  PCB (Printed Circuit Board), the Chinese name is a printed circuit board, also known as a printed circuit board, is the support body of electronic components, and is a carrier for electrical connections of electronic components. Its basic classification is: 1. According to the number of layers: based on the number of layers of copper foil One-piece panel: The wires only appear on one side, and there are many strict limits on the design line (because there is only one side, the path that cannot cross the wiring room must be around alone), so only this type of board is used in the early circuit. Double panels: There is wiring on both sides of this circuit board. Double panels solve the problem of single panels because of staggered wiring (can be guided to the other side). It is more suitable for more complex circuits than a single panel. Multi-layer PCB: Use one double-sided as the inner layer, two single-sided for the outer layer or two double-sided as the inner layer, and the two sin

 Microwave antenna is one of the important applications of high frequency microwave PCB. As a carrier of high-speed signal transmission and a platform connecting different communication modules of the entire electronic system, it plays a very important role in the field of wireless communication. With the rapid development of wireless communication technology, the application scope of microwave technology is also very wide. The most common application is to transmit information, and the microwave antenna is the most important part of the microwave communication system.     In the 5G era, the development trend of the communication industry towards the high frequency band puts forward higher requirements for microwave antenna PCBs. Related products are widely used in the fields of communications products, satellite communications, satellite navigation, and automotive electronics, especially in the future from 4G, 4.5G to 5G Gradually extending, the construction of small base stations pro

 Products designed by excellent engineers must meet design requirements and production processes at the same time. Any defect in one aspect cannot be considered a perfect product design. Standardize the product's circuit design, process design, PCB design, and other related process parameters, so that the production of physical products produced meets technical specifications such as productivity, measurability, and maintenance. In the process of product design, build the advantages of process, technology, quality, and cost. This article will allow you to quickly understand the basic concepts of PCB design . 1. FR4 board FR-4 is a glass fiber oxygen resin covering a copper plate. A substrate on the circuit board can be divided into a general FR4 board and a high TG FR4 board. TG is the temperature of the glass conversion temperature, i.e. the melting point. The circuit board must be flammable, and it cannot be burned at a certain temperature. It can only be softened. At this time,

 Printing circuit boards (PCBs) are used in almost all electronic products. As a result, the designer continues to promote PCB limitations and engineered integrated circuits with fewer size requirements and other key connections. Therefore, in order to meet the growing demand for connections and rapid advances in electronic manufacturing, PCB component manufacturers must conduct comprehensive quality assurance testing. Manufacturers will conduct tests such as online testing or X-ray inspection to check components and detect defects in almost all micro packaging. Defects (such as size or power consumption) in the characteristic definition directly affect the single board on which they occur and pose risks to the manufacturing process and the supply chain. The ultimate goal of the manufacturer is to achieve higher output at a lower cost and lower defect rate. Therefore, even occasional flaws can destroy the goal. This article focuses on various quality control testing techniques in the c

 The circuit board is an important electronic component, the support body of the electronic component, and the carrier of the electronic component's electrical connection. Because it is made of electronic printing, it is called a "print" circuit board. A printing circuit board is a bridge that carries electronic components and connects the circuit. It is widely used in the fields of communication electronics, consumer electronics, computers, automotive electronics, industrial control, medical equipment, national defense and aerospace, and other fields. Lack of electronic components. What does the future hold for the circuit board? 3D printed electronics 3D printing technology is one of the most interesting and innovative technological advancements in recent years. From 3D printed tools to complex digital designs, 3D printing technology is traversing almost every industry, and PCB manufacturing is no different. The technology is already being used in PCB manufacturing and

PCB proofing is divided into rigid PCB proofing and flexible PCB proofing, flexible PCB proofing and rigid PCB proofing. Common materials for rigid printed circuit boards include: phenolic paper laminate, epoxy paper laminate, polyester glass felt laminate, epoxy resin glass fiber laminate; flexible PCB prototypes typically include: polyester film, polyamine amine film, fluorinated ethylene acrylic film. These materials are difficult to refine and collect, so the cost of a PCB prototype circuit board is very high. Many times, we hope to recover on the original basis to better lay the foundation for PCB proofing operations. Essence When customers do PCB proofing, they often put forward higher requirements for manufacturers' time to hand in, processing complex models, and product quality. So what problems do you need to pay attention to in the PCB proofing process? What are PCB proofing problems? First, pay attention to the number of proofs. Enterprises often need to make a batch of
