A PCB copper plane is a layer in a PCB with copper on it after etching, usually traces and pads or power and ground planes. PCB copper material Copper foilCopper foil is the cathode portion of the electrolytic material, which is deposited on a continuous thin metal foil layer on the PCB substrate. You can …
Copper laying in PCB design is an important part of circuit board design. The so-called copper filling uses the idle space on the PCB as a reference plane and then fills it with solid copper. These copper areas are also called copper fillings. The significance of laying copper is to reduce the impedance of the ground wire, …
Today, radio frequency circuits are used in various electronic products, including medical, industrial control, and communication products. What is an RF Circuit Board? The frequency range of radio frequency is usually 300Khz-300Ghz. The signal above 300Khz is radio frequency, and the signal above 300Mhz is microwave. There is a considerable difference between radio frequency and …
Before printed circuit board design begins, designers should take some basic steps to ensure a successful project, such as management and scheduling. Time and resources must be allocated to the project, including buffers for design changes or bugs that require changes to the schematic and layout. All too often, PCB designers have to struggle to …
Regarding the design of the PCB circuit board, do you know what the design process is there? 1. Preliminary Preparation Preliminary preparation includes preparing component libraries and schematic diagrams. Before proceeding with PCB design, we must first prepare the schematic SCH component library and PCB component packaging library. PCB component package library is best established …
Datum Point Design Classification According to the position and function of the reference point on the PCB, it can be divided into: mosaic reference point, unit reference point and local reference point (as shown in Figure 6). Benchmark Structure Composition datum and unit datumShape / size: 1.0 mm diameter solid circle. Resistance welding window: the …

PCB Stack Design Stacking Mode The recommended stacking method of PCB is foil stacking.(show as Figure 1)Note: There are two kinds of PCB stacking design: one is the structure of copper foil with core, which is called foil stacking for short; The other is the core stack method. The core lamination method can be used …
Routing Design Line width / line distance and safety requirements for route The design of line width / line distance is related to copper thickness. The larger the copper thickness, the larger the width / line distance is needed. The recommended line width / line distance for outer layer / inner layer is shown in …
