What are the Advantages of Copper Base PCBs

图片
          Copper base PCB, that is, a printed circuit board with copper as the base material, is widely used in various field of electronic products, especially in power electronics, power modules, LED lighting and automotive electronics. Compared with other types of PCBs, copper base PCBs have many unique  advantages , which make them irreplaceable in specific applications. So what are the advantages of copper base PCBs?   1. Excellent  H eat  D issipation  P erformance Copper has a higher thermal conductivity (about 400W/m · K), which is much higher than aluminum (about 200W/m · K) and FR4 substrates (about 0.3W/m · K). This makes Copper base PCBs excellent in heat dissipation performance, and is particularly suitable for application scenarios that require efficient heat dissipation, such as high-power LEDs, power modules, and high-frequency electronic devices.     2.  High  M echanical  S trength Copper-based materials have high hardness and strength and can withstand greater mechan

Why Medical PCBA Needs ISO13485 Qualification Certification

          In our life, PCBA is widely used. In particular, the development of medical technology has benefited too many people, and it is mainly due to the improvement of SMT technology, which can promote the maturity and stability of PCBA control boards. So why does medical PCBA processing require ISO13485 qualification certification?   1.  The manufacturing process of medical PCBA involves a variety of medical electronic equipment and materials, such as sensors, displays, electronic components, connecting wires, etc.  The quality of these devices and materials directly affects the quality and safety of medical device. The ISO13485 standard puts forward detailed requirements and standards for the production process of medical PCBA processing, including production equipment, raw materials, technological process, quality control, etc., to ensure the quality and safety of medical PCBA processing.     2. The quality and safety of medical devices is one of the key factors  affecting  the  

Why LED Lights Need to Use PCBs

          LED lights have become a main force in lighting technology due to their energy-saving, high efficiency and long life characteristics. Although LED lights can be directly connected to a DC power source to emit light, such as connecting two ends of dry battery, why is it still necessary to use PCB in practical applications?   1.  The Necessity of Power Conversion Household power is usually AC, while LED lights require DC to work. A key function of a PCB is to convert AC into DC. By integrating the rectifier circuit on the PCB, the LED lights can obtain a stable DC current from the AC power source. This not   only ensures the normal lighting   the LED l ight , but also accurately  controls the voltage and current, protects the LED chip and  extend   its  service life.     2.   Realization of  D iversified  F unctions LED lights are not only used for lighting, but are also widely used in decoration, display s   and other scenes that require special lighting effects.   To achieve

Key Requirements of Server and Data Storage PCB

          Servers and data storage place stringent demands on PCBs to ensure high performance, reliability, and efficiency.  These  demand s stem from the need to process large amounts of data, achieve high-speed communications, and provide uninterrupted services.  Here are some key requirements for PCBs in the server and data storage space: 1. High  D ata  R ate s   and  H igh  B andwidth With the increasing demand for data-intensive applications and high-speed communication protocols, PCB must be capable of supporting high data rates and high bandwidth. To achieve this goal, technologies such as controlled impedance,  carefully   designed routing, and advanced materials are used to minimize energy loss in the signal and ensure data integrity.     2. Thermal  M anagement Servers and data storage systems generate a lot of heat during operation, which, if not managed properly, can lead to performance degradation or component failure. Therefore, PCBs must employ thermal management soluti

What are the Requirements for PCB Manufacturers' Shipping Packaging?

          PCB is one of the essential components of electronic products, and its quality directly affects the performance of the entire product.  In order to protect the PCB and ensure the reliability of the product, the PCB manufacturer will pack the PCB. So what are the requirements for PCB packaging?   1.  Anti-static Because static electricity will interfere or damage the circuit, anti-static measures need to be taken during the PCB packaging process.   For example: PCB manufacturers will package PCBs in conductive layers or static shielding bags, or use packaging equipment with static elimination devices, etc.     2.  Waterproof and  M oisture - proof PCB are sometimes affected by humid environments, especially during transportation and storage. Therefore, during the PCB packaging process, it is necessary to pay attention to waterproof and moisture-proof. For example: PCB manufacturers will choose packaging materials with good airtightness, and add hygroscopic agents, moisture-pro

High TG PCB: A Reliable Partner for Automotive Engines

图片
          With the continuous advancement and development of automotive technology, electronic systems are being used more and more widely in automobiles. Many key components in automobiles, such as the engine control unit (ECU), power management system, and sensors, rely on high-performance PCBs. Among them, high TG PCBs play a vital role in automotive engines due to its excellent high-temperature resistance.   What is High TG PCB? When the temperature rises to a certain critical value, the PCB substrate will change from a glass state to a rubber state. The critical value of this temperature is the TG value. High TG PCBs refer to those circuit boards whose glass transition temperature is higher than that of regular PCBs. Usually, the TG value of standard PCBs is around 130 ℃ , while the TG value of high TG PCBs is 170 ℃  or even higher.     Application of High TG PCB in Automotive Engines When an automotive engine is running, it will generate extremely high temperatures, which places
