Professional PCB Manufacturer
Victory is a professional PCB manufacturer which established in 2005. Adhere to be a specialized manufacturer for multiply species, small to medium series, and quick turn production, we insist to provide 3H(high quality, high precision and high density) PCBs to our customers.
Immersion gold plating is an interaction that applies an extremely slim layer of gold by dislodging the surface molecules. This implies the covering isn't extremely thick, ordinarily somewhere in the range of three and eight miniature inches.
If a PCB includes three or more layers or sheets of copper foil that are isolated from each other coating) and linked together to form a single component, it is called a high-density multilayer PCB. It must have at least three layers of conductive material buried in the material's center.
The printed circuit board (PCB) manufacturing process requires a complex procedure to ensure the performance of the finished product. Though circuit boards can be single, double or multilayered, the fabrication processes used only differ after the first layer’s production. Due to differences in the structure of the PCBs, some may require 20 or more steps during manufacturing.
Printed circuit boards (PCBs) have been an integral part of electronics for many years. Through the years, electronic devices are getting smaller and more complex and so are the PCBs needed to connect the components in an efficient manner. As robotics and electronic design begin to be taught as early as grade school, the art of PCB layout becomes more meaningful. What follows are 5 common myths about PCB layout:
I don't know when the black PCB became a representative of high-end electronics in the minds of many people. But that's true today many major manufacturers have adopted black PCB in motherboard design, such as Apple, Asus, MSI and so on. Some PCB manufacturers also use black as a premium parameter. So is the black PCB really as high-end PCB as people feel? Today we will specifically discuss this issue.
When 'dissecting' the interior of every Apple MacBook, the skilled engineers are impressed with the clean black circuit board and the components are neatly arranged inside. Unlike the majority of other electronics firms that choose green for the circuit board, Apple chose black. Why so?
The question can and probably should be asked: “Is it important to understand the PCB fabrication process?” After all, PCB fabrication is not a design activity, it is an outsourced activity that is performed by a contract manufacturer (CM). Although, it is true that fabrication is not a design task, it is done in strict adherence to the specifications that you provide to your CM.
One of the most important calculations in high current applications is the cross-sectional area of a trace. IPC 2152 shows (conservative) cross-sectional areas needed for particular amperages, but designers are left alone to calculate the area of a trapezoidal trace. Sure, the area of a trapezoid is h*(b1+b2)/2, h is obviously copper weight (in mils!) and b1 is obviously the trace width, but what is b2? Your PCB manufacturer’s sales and planning departments will know how much smaller the top of the trace is than the bottom, so be sure to ask them. Note that the difference varies from manufacturer to manufacturer.
Classification according to the number of circuit layers: divided into single-sided, double-sided and multi-layer boards. Common multi-layer boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boards can reach dozens of layers. The PCB board has the following three main types of division:
The main purpose of thickening copper plating is to ensure that there is a thick enough copper plating layer in the hole to ensure that the resistance value is within the range of the process requirements.
Double-sided PCB board is a very important PCB board in the circuit board. There are double-sided circuit board metal base PCB board, Hi-Tg heavy copper foil circuit board, flat and winding double-sided circuit board, and high-frequency circuit board on the market. PCB, hybrid dielectric base high frequency double-sided circuit board, etc., it is suitable for a wide range of high-tech industries.
