Have you noticed that now more and more of our lighting is using led lighting.What is LED? Compared to the traditional light bulbs, LEDs have lower power consumption, longer lifetime and higher energy efficiency. In the PCB industry,when we say LED PCB, it refers to the pcb used for LED lighting, if you are looking for a suitable LED PCB for your lighting system, this article may bring you something. WHAT ARE LEDS COMPOSED OF?LED is an initial light-emitting diode that produces light when an electric current passes through. LEDs typically have negative and positive electrodes, which generate light in the visible light region.The LEDS are glued to the PCB by soldering process and have electrical connections for lighting.Since light-emitting diodes dissipate a lot of heat when they are in use, when you are designing LED, the metal core is usually the best choice for LED PCB, it is because that it dissipates heat more faster. Among them, the metal material aluminum is the most widely used
1、 The Function and Significance of High Frequency Board in Drone PCB A high-frequency board is a printed circuit board specifically designed for processing high-frequency signals. In unmanned aerial vehicles, the processing of high-frequency signals is very important. Drones typically use high-frequency devices such as radar, communication equipment, and radio equipment to achieve their functions. And these high-frequency devices require high-frequency boards to ensure the stability and reliability of signal transmission. High frequency boards can effectively reduce signal transmission loss and improve transmission efficiency. Therefore, using high-frequency boards can improve the performance of drones and increase their stability and reliability. 2、 Application of High Frequency Board in Drone PCB 1. Signal transmission The signals generated by high-frequency devices in drones must be transmitted to the corresponding positions through the transmission line of the drone PCB. T
1. Appearance observation method: The number of layers of a PCB board can be preliminarily determined by observing its appearance with naked eyes. Under naked eye observation, multi-layer PCB boards appear thicker, while single-layer or double-layer PCB boards appear thinner. However, due to the trend of miniaturization in modern electronic products, many PCB boards are very thin, making it difficult to determine the number of layers solely based on their appearance. 2. Line density method: By observing the circuit density on the PCB board, the number of layers can be determined. In general, the circuits on multi-layer PCB boards are denser and more complex between circuits. By comparing with empirical data, the number of layers of PCB boards can be preliminarily determined. 3. Cross hair method: This is a commonly used judgment method that requires the use of a microscope and a crosshair ruler. Using a microscope to observe the edges of a PCB board and measuring the thickness
Firstly, the first step in the production of new energy vehicle PCB boards is the design of circuit board drawings. The designer draws the layout and circuit connection drawings of the circuit board based on the functional and dimensional requirements of the electronic equipment of the new energy vehicle. The accuracy and rationality of design drawings are crucial for the subsequent manufacturing process. Next is the plate making and electroplating of the circuit board. Plate making is the process of transferring design drawings to photoresist through lithography technology, and then gradually exposing the copper layer through chemical corrosion to form the required circuit lines. Next, the copper plate is immersed in an electroplating bath, and through the action of current, a layer of copper foil is formed on the circuit line to enhance conductivity and durability. The third key step is drilling and deburring. In this step, the high-speed drilling on the small lathe drills n
In recent years, with the continuous development of electronic products and the further advancement of intelligence, the design of printed circuit boards (PCBs) has become increasingly important. The design of PCB multilayer structure occupies a core position in modern electronic equipment, and its rationality directly affects the performance and reliability of electronic products. Firstly, let's take a look at the design principles of a multi layer PCB structure. Firstly, the selection of layers is very important. The more layers there are, the higher the complexity of signal transmission, so a balance between circuit complexity, electromagnetic interference, and cost needs to be considered in the design. Secondly, in the design of PCB multilayer boards, the signal circuits of each layer should be reasonably arranged. There should be sufficient spacing between different signal lines to avoid mutual interference. In order to improve the speed of signal transmission and reduce e
With the continuous development of technology, LED circuit boards are playing an increasingly important role in the lighting industry. They not only provide high brightness lighting effects, but also have advantages such as energy conservation, environmental protection, and long service life. In order to further promote the development of LED light circuit boards, new design trends are constantly emerging. Today, the editor will delve into the current 5 cutting-edge LED light board PCB design trends and look forward to the possibilities that technology can bring to the future. Firstly, customized design has become mainstream. Traditionally, the design of LED light circuit boards has been relatively uniform, but now the market demand is constantly personalized, and people's requirements for lighting are becoming increasingly diverse. Therefore, more and more lamp panel manufacturers are providing customized design services to meet the needs of different customers. Customized des

PCB circuit board reflow soldering is one of the common welding methods in the electronic assembly process. It firmly fixes electronic components on the PCB board by applying appropriate heat and melted solder paste to pre arranged welding points. However, some common problems may also arise during the reflow soldering manufacturing process. The manufacturer of intelligent circuit boards will introduce these issues and corresponding solutions.1、 Tin splashing on the board surfaceProblem description: Tin splashing on the board refers to the excessive amount of solder around the welding point during reflow soldering. This may cause damage to components near the welding point, and even cause short circuits or welding failures.Solution: There are several methods to solve the problem of tin splashing on the board surface. Firstly, check whether the size and position of the welding points are appropriate to avoid excessive soldering caused by design defects. Secondly, adjust the
In the manufacturing of electronic products, PCB (Printed Circuit Board) is a very important component. The number of layers on a PCB board determines the complexity and functionality of the circuit. Therefore, understanding and accurately determining the number of layers of PCB boards is crucial for the design and manufacturing of electronic products. So, how to accurately determine the number of layers of a PCB board? The editor of the manufacturer of intelligent circuit boards will take you to understand. Generally speaking, the following methods can be used to make judgments: 1.
