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.
Roger PCB is commonly known as a printed circuit board. It very important in any automated device that is being used, that why it necessary for your devices get a quality to roger PCB for proper functioning. Many materials come together to design a standard printed circuit board, most of the materials used contain specific functions and features to develop a well functioning roger PCB.
In the printed circuit boards (PCBs), fire retardant 4 (FR4) material is one of the most widely used materials in the assembly and fabrication of PCB.
