PCBs from  PCB manufacturers  are often flat laminated composites comprised of non-conductive substrate materials with copper circuitry layers concealed within or on the exterior surfaces.   They might be as basic as one or two layers of copper, or as complex as fifty layers or more in high-density applications. The flat composite surface is perfect for supporting the soldered and connected components to the PCB, while the copper conductors electrically connect the components. As substrates and components, PCBs may be made from several materials. Material selection is determined by the application's requirements, as different material choices give the circuits varying qualities that facilitate performance in specific circumstances.     Designers may select materials depending on the electrical performance for high-speed applications, mechanical or thermal durability, or both - for example, automobile under-the-hood uses.   The first thing to understand abou...

Seekrun bikes are full of technology to help you get the most from your ride, no matter what your fitness level or riding habits. One of these technologies is the seekrun bike display, and we'll cover everything you need to know about our e-bike displays and controllers.   Whether you plan to use your hybrid e-bike every day or do the occasional family bike ride, it's important to familiarise yourself with our features to get the most out of every ride. What is an e-bike display ? You will find that most road e-bikes have a screen on the front of the bike, usually in the middle of the handlebars. This screen is essentially the brain of your e-bike and is used to display important statistics and information about your ride.   From here, you can see.   The current speed of your bike The maximum speed of your bike The average speed of your current cycle Distance travelled one way Total mileage The remaining life of your e-bike's battery Our display offers 2 viewing angles an...

  In our increasingly mobile and technology-driven world, videoconferencing is becoming very popular, especially for companies that have employees working from home. There are many services and programs available to host and join a videoconferencing call and a   webcam  is used to show your live video.   For help with installing, testing, and using a computer webcam, and determine if your laptop has a built-in webcam, select a link below.   How to install a webcam Today, most webcams are universal, meaning they work on almost any computer. Follow the steps below to connect and install a webcam on your computer.   Turn on your computer and make sure the operating system is loaded. Most webcams have a USB cable connected to them. Plug the USB cable into an available USB port on your computer. USB ports are on the back of the computer or the sides of a laptop. Newer operating systems, like Windows 8 and Windows 10, should recognize the webcam as connected. The...

With the rapid development of optical communication, more and more fiber optic cables are increasingly used in different environments. What if under harsh conditions? Then it's crucial to ensure your cables smooth and reliable operation when transmitting data. This is where armoured cable comes into play. An armoured cable, as its name suggests, is protected against mechanical damage, whereas an unarmoured cable not being protected. What is the difference between them? And why should we choose armored cable over unarmoured cable? You my find answer in this post.   Amoured Cable Overview   Armoured cable has an extra layer of protection to keep it from being cut or abraded. The armor layer of coax cable is a foil wrap that is ribbed like corrugated metal to allow for flexibility, around the inside and outside of that wrap is a flooding compound to keep moisture from penetrating the cable and causing an impairment. The internal structure of 4 core armoured cable consists of many...

  A power divider is a device that divides the energy of an input signal into two or multiple outputs of equal or unequal energy, and can also combine the energy of multiple signals into one output in reverse, which can also be called a combination. router. A certain degree of isolation should be guaranteed between the output ports of a power divider.  Power divider   is also called overcurrent divider. It is divided into active and passive. It can evenly distribute one signal into several outputs. Generally, each branch has a few dB attenuation. The signal frequency is different, and the attenuation of the divider is also different. Different, in order to compensate for the attenuation, a passive power divider is made after adding an amplifier. The technical indicators of the power divider include frequency range, withstand power, distribution loss from main circuit to branch, insertion loss between input and output, isolation between branch ports, voltage standing wave ...

LED screens  are a major technological development, but most people don't know what they are or how transparent they are. We'll look at these screens and explain how they work.   What is a transparent LED screen? Screens have a glass-like surface that provides users with high-definition effects. These screens are becoming increasingly popular for a variety of reasons, starting with the fact that they can be installed anywhere there is enough space.   These LED screens are perfect for large areas and outdoor advertising, often resembling glass curtain walls.   Many people also use these screens as digital signage screens or transparent video walls. The beautiful led displays offer better display effects and people use them for advertising media and products.   Transparent LED display installation: How does it help? Installing LED displays can help in many ways. It is suitable for cost savings, noise reduction, added convenience, etc. Here are some of the best rea...
