What is PCB Embedded Component Process? The resistance and capacitance buried in multi layers PCB process is a process of burying resistors and capacitors inside the PCB board. Usually, the resistors and capacitors on the PCB are directly soldered on the board through mounting technology, while the buried resistor and capacitor process is to embed the resistors and capacitors into the internal layer of the PCB board. This kind of printed circuit board consists of a first dielectric layer, a buried resistor, a circuit layer and a second dielectric layer in order from bottom to top. Among them, the part of the buried resistor without a circuit layer on the buried resistor is covered with a polymer isolation layer, and the surface of the polymer isolation layer is roughened, the surface roughness Rz is bigger than 0.01 μm, and the thickness of the polymer isolation layer at the corners is at least 0.1 μm. The printed circuit board of the utility model covers a layer of polymer isolation layer on the surface of the buried resistor, thereby protecting the buried resistor from being attacked and corroded by chemical chemicals during subsequent wet processes such as browning and super-coarseness, and improving the efficiency of manufacturing buried resistors. Resistor plate process capabilities further promote the application of buried resistive plates to inner layer buried resistors.

How Can I Reduce and Optimize the Cost of My PCB in A Best Way? – Series 2 At our latest blog, may the readers have understood the factors that will affect the PCB price, or maybe one of your have put it into practice that get a price lower than your budget. However, people are always not satisfied by the existing situation. If this is bother you as well, keep reading since this time we are going to sharing some useful tips that enable to optimize your PCB price until to the best. Reduce board complexity It can be said that try to simplest your design/layout and make it easy to fabricate is the simplest way to reduce your PCB cost. The more complex and irregular the forms, the higher the cost. Just remember: for every circuit board, no need to maintain a fancy diagram to demonstrate its excellence, perform functionality correctly is enough. Design it in right size and thickness Design your board in right size doesn’t means make it smaller as possible. You must know, if your design is complex and layouts are density, that means maker need to spend more time to assemble them. Highly compact sizes are always expensive, don’t skimp when it counts. Otherwise, more money will be spent to afford what you saved. And in theory, the more layers and thickness the board, the more cost that manufacturer spend. Numerous layers in the PCB will have an influence for holes and diameters. It is recommended that if thinner thickness is enough, then just do it. Shapes, holes and rings should be regularly Normally, keep the PCB as square or rectangular shapes is cheaper than irregular shapes like pentagon. And large holes and rings enable to smooth the production run and easy to create. For smaller holes and rings means the driller must be smaller and delicate control. https://www.bestpcbs.com/blog/2023/10/how-can-i-reduce-and-optimize-the-cost-of-my-pcb-in-a-best-way/

The Differences Between Copper PCB and Heavy Copper PCB? With the fast development of digital era, printed circuit board (PCB) has won a huge market in the electronic industry. Nowadays, electronics can be found everywhere, I can say for each electronic products, you will find a PCB or several pcbs are inside. But not every PCB are the same, each printed circuit board plays its unique roles. When it comes to copper pcb, may someone will think about heavy copper pcb, or even think they are the same. But actually, they are totally different, totally from constructure and functions. What is Copper PCB? Copper PCB, also known as Copper Core PCB, Copper-based PCB or Copper Clad PCB, which is a type of metal core PCB (MCPCB) that uses copper core as the base substrate. Among all of the PCB types, copper clad pcb is well-known for its extreme high thermal conductivity, which enables to achieve to 401W/m.K, that’s why some people think it is the king of the metal core PCB. http://www.bestpcbs.com/blog/

Answers to Common Metal Dome Questions Customers often ask some questions when making early purchases. After summarizing these problems, today I will introduce to you the common problems of metal domes and what should be paid attention to during the installation of metal domes. The first is the color of the metal dome: the metal dome is mainly made of stainless steel, with a silver surface. Some customers will need to surface treat the metal dome. The surface of the nickel-plated metal dome is golden yellow. This nickel-plated metal dome can better prevent surface corrosion during use and is more durable. Nickel-plated metal domes feel better in hand and work better than ordinary metal domes. In addition to the metal dome, the color of the PET glue in the metal dome array has also become a focus of some customers. The PET glues we often use include white, transparent and black, among which white and transparent PET are widely used. However, the actual application still needs to be selected based on the needs of the customer and understand the metal dome array PET. There will also be some customers who will ask some professional questions, and I will explain them here. Why does the Dome array PET tape lift up during use? In fact, PET is glued to the PCB, and the metal dome array should be flat under normal circumstances. After being used for a period of time, the outline of the dome array may tilt, causing dust to enter the PET, causing undesirable phenomena. So what is the reason for this? https://www.metal-domes.com/blog/2023/10/17/answers-to-common-metal-dome-questions/

Due to the different surface structures of ceramic susbtrates and metal materials, welding/soldering often cannot wet the ceramic surface or form a strong bond with it. Therefore, the joining of ceramics and metals is a special process, which called as metallization. What Ceramic Metallization Technology Is? Ceramic metallization refers to the process of firmly attaching a thin layer of metal film to the surface of a ceramic material to achieve a bond between the ceramic and metal. There are various methods for ceramic metallization, commonly including molybdenum-manganese (Mo-Mn) method, directly copper plate (DPC), directly bonded copper (DBC), active metal brazed (AMB) method and more.

Do you know the relationship between copper thickness and circuit width & spacing? We know the precision control and performance of a product are paramount, only know that PCB can be built with a nice function, so, to understand the intricate relationship between copper thickness and circuit width and spacing is pivotal. These two parameters are like the gears of a well-oiled machine, interlocking in ways that significantly influence the printed circuit board‘s functionality, signal integrity, and manufacturability. If the designer does not consider the relationship between these two, the design may need to be modified in subsequent production. In order to avoiding this information, let’s embark on a deeper exploration of this dynamic relationship to uncover its nuances and implications now, Frist of all, we need to know some basic information about PCB, like copper thickness, circuit width and spacing. The Essence of Copper Thickness Copper, known for its exceptional electrical conductivity, is the lifeblood of any PCB. The copper thickness refers to the amount of copper deposited onto the board’s surface during fabrication. It’s the foundation upon which the traces, the intricate pathways that carry electrical signals, are built. The standard copper thickness is often measured in ounces per square foot (oz/ft²) or micrometers (µm). Common options include 1oz (35µm), 2oz (70µm), and even higher, it depends on customer’s requirement. http://www.bestpcbs.com/blog/2023/09/do-you-know-the-relationship-between-copper-thickness-and-circuit-width-spacing/
