The LED lighting PCB comes into being with the rapid development of printed circuit PCB industry. Some LEDs were soldered on PCB to created lighting electronic products. As we all know that LED will generate more heat compared with other electronic parts, which required the PCB to have better ability for dissipating heat. For this special requirements, metal core PCB are frequently used on LED PCB, especially aluminium core PCB. This is because the aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB. The application of LED PCB Telecommunications:LED indicators and displays are always used for telecommunications equipment because of the surrounding machinery, the excellent heat transfer ability. So aluminum-based LED PCBs is extremely useful in this application. Automotive: Aluminum PCB LEDs also used in cars on indicators, in headlights and brake lights, and other applications. The durability and competitive price makes these Aluminum Fr4 PCB Manufacturer ideal within the automotive industry. Computer: LED displays and indicators are becoming more and more common within computer applications, and the heat sensitivity of computer machinery makes aluminum PCB LEDs the ideal solution. In addition to LED applications, computer parts like power devices and CPU boards are commonly use aluminum PCBs because of their ability to dissipate and transfer heat. Medical: Lighting tools used in surgeries and medical examinations commonly use high-powered LED lights, and these LED lights often use aluminum PCBs. This is primarily due to the durability and heat transfer capabilities of aluminum PCB LEDs â?? this ensures medical equipment is functioning properly regardless of the number of patients cycling through a medical office. In addition to lighting tools, medical scanning technology often uses aluminum PCBs as well. Pcbmain supplied affordable LED PCBs Free PCB quotation is just a click away.

What is HDI PCB High density interconnect (HDI) PCB, represent one of the fastest growing technologies in PCBs. Because of its higher circuitry density than traditional circuit boards, the HDI PCB design is able to incorporate smaller vias and capture pads, and higher connection pad densities. HDI Boards contain blind and buried vias and often contain micro vias of 0.006 or less in diameter. By using HDI technology, designers now have the ability to place more components on both sides of the raw PCB if desired. Now as the development of via in pad and blind via technology, it allow designers to place smaller components closer together. This means faster transmission of signals and a significant reduction in signal loss and crossing delays. HDI PCB is regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices. Advantages of HDI PCB The most common reason for using HDI technology is a significant increase in packaging density. The space that obtained by finer track structures is available for components. In addition, overall space requirements are reduced will result in smaller board sizes and fewer layers. Usually FPGA or BGA are available with 1mm or less spacing. HDI technology makes routing and connection easy, especially when routing between pins.
Thick-Copper PCB With the highly development of telecommunications and electronics industry, thick copper board is widely required by PCB customer. Thick copper PCB is mainly used for central power system and power electronic devices, which is because it enables the board to conduct higher current and decrease the product size. China thick copper board mean the finished copper thickness of the board is more than 4OZ(140um), this is the most important factor for us to compare the thick copper PCB from those standard PCB with 1OZ or 2OZ copper.

High-TG PCB High Temperature PCB fr4 Material The Glass Transition Temperature (Tg) is one of the most important properties of any epoxy and is the temperature region where the polymer transitions from a hard, glassy material to a soft, rubbery material. Circuit board material must flame-resistant, it canâ??t be burned at a certain temperature and only be soften. The temperature point is called the glass transition temperature (Tg). The higher Tg point means higher temperature requirement during lamination. And the Aluminum clad Circuit Boards will be hard and crisp, which will affect hole and the electrical properties. Ordinary PCB materials at high temperatures, not only will be soften, deformation, melting and other phenomena, but also the mechanical and electrical properties decline sharply. General fr4 Tg is 130-140 centigrade, moderate Tg is greater than 150-160 centigrade, High-Tg is greater than 170 degrees. The higher of Tg, the better performance of PCB heat resistance, moisture resistance, chemical resistance, stability and other characteristics. FR4 is a code name for grade of Epoxy Glass material. Tg means Glass Transition Temperature. When the working temperature reaches to the melting point, that means the temperature exceeds the Tg value, the status of pcb material will be changed from glassy to liquid, which will affect the function of pcb. And this value is related to the stability of the pcb dimension. As usual, made with Tg â?¥ 170â?? pcb material, which is called high Tg printed circuit board. With the rapid development of the electronics industry, high Tg material is widely used in computer, communication equipment, precise apparatus and instrument and etc.
What is High Frequency (HF) PCB Electronic devices with high frequency is the developing tendency nowadays, especially in wireless network. Satellite communication growing rapidly, information products move towards high speed and high frequency. Thus developing new products always need to use high frequency substrate, satellite system, mobile telephone receiving base station and so on, these communication products must use high frequency PCB. The features of Thick Copper PCB. DK should be small and stable enough, usually the smaller the better, high DK may lead to signal transmission delay. DF should be small, which mainly affect quality of signal transmission, the smaller DF could make smaller signal wastage accordingly. The thermal expansivity should be the same with copper foil as much as possible, because the difference will lead to copper foil separated in the changes of cold and heat. Water absorptivity must be low, high water absorptivity will affect DK and DF when in the wet environment.
What is Flexible PCB? Flexible printed circuit boards, also called Flexible PCBs or Flex PCBs, derive their name for their ability to enable the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to the circuit board. Immersion Tin PCB are characterized by a distinctly patterned printed circuitry and component arrangement highlighted by a malleable base material. What are Advantages of Flexible Printed Circuit Boards? Flexible printed circuit boards offer a number of potential benefits including: Saving Space. Flex PCB design requires only about 10 percent of the space and weight of an ordinary circuit board assembly, offering greater installation and packaging freedom. The inherent flexibility also permits tighter bend capabilities. Maximum Reliability. A flexible printed circuit board requires fewer interconnects, which in turn requires fewer contact crimps, connectors and solder joints. Simply put, a flexible PCB board does not contain as many potential sources for failure, which enhances their reliability. Enhanced Capabilities. The flexible printed circuits boards are compatible with virtually any type of connector or component and works well with options such as ZIP connectors. They also perform extremely well in extreme temperatures and offer superior resistance to radiation and chemicals. Cost Savings. Cost-saving advantages of Flexible PCBs include reduced material and packaging demands, lower parts replacement costs and assembly errors that could result in the need for repairs. Thsse benefits make flex PCBs ideally fit for a wide range of applications in industries such as Military, Transportation, Medical, Consumer Electronics, Automotive, Aerospace, Communications and Industrial.
Rigid-Flex circuit boards are composed of a combination of rigid and flexible circuit boards that are permanently connected to one another. The proper application of Rigid-Flex circuit boards offers optimum solutions for difficult, limited space conditions. This technology offers the possibility of a secure connection of device components with the assurance of polarity and contact stability, as well as a reduction in plug and connector components. Additional advantages of pcb bare board are dynamic and mechanical stability, the resulting 3-dimensional freedom of design, simplified installation, space savings, and maintenance of uniform electrical characteristics. Use of Rigid-Flex circuit boards can reduce the total cost of the final product. Rigid-Flex circuit boards give you unlimited freedom of packaging geometry while retaining the precision density and repeatability of printed circuits. As a high reliability replacement for wire and wire harness assemblies, flex circuits provide a significant cost savings with no reduction in performance.
Aluminum PCB Advanced Circuits Specification Aluminum Printed Circuit Boards Contain a Thin Layer of Thermally Conductive Dielectric Material that Transfers Heat. There are many names for these products; Aluminum clad, aluminum base, Metal clad printed Circuit Board (MCPCB), Insulated Metal Substrate(IMS or IMPCB), Thermally conductive PCBs, etcâ?¦ but they all mean the same thing and perform the same way. How Are Aluminum PCBs Made? A thin layer of thermally conductive but electrically insulating dielectric is laminated between a metal base and a copper foil. The copper foil is etched into the desired circuit pattern and the metal base draws heat away from this circuit through the thin dielectric. Operating theory: The power device surface mounting on circuit layer, it is ideally suited for the mounting of high power light emitting diodes (LEDs) easily dissipating the heat generated by power devices.
