Matters needing attention in the design of the clock on the circuit board are mainly considered from three aspects. 1. PCB layout 1) the clock crystal and related circuits should be arranged in the center of the PCB with a good stratum, not near the I/O interface. The clock generation circuit can not be made […]

It is undoubtedly the goal of this product to have a PCB that can withstand any electrical, mechanical or structural adverse effects throughout its life expectancy. Circuit board construction process. These goals are equally divided between PCB manufacturing and PCB assembly. For manufacturing, the threat is cracking and breaking, while for assembly, the threat is […]

The analysis and design of power supply system (PDS) is becoming more and more important in the field of high-speed circuit design, especially in computer, semiconductor, communication, network and consumer electronics industries. With the inevitable further proportional reduction of VLSI technology, the supply voltage of integrated circuits will continue to decrease. As more and more […]

It is easy to form two basic parasitic elements that may cause problems in PCB design: parasitic capacitance and parasitic inductance. When designing a circuit board, placing two tracks close to each other will cause parasitic capacitance. You can do this: place one trace on top of another trace on two different floors; Or on […]

1, PCB layout/wiring, the impact on electrical performance is often seen in books about electronics, saying “digital ground wire should be separated from analog ground wire”. Anyone who has laid the board knows that it is difficult in practice. To lay out a better board, first of all, you have to have an electrical understanding […]

At present, high-speed PCB design is widely used in communication, computer, graphics and image processing and other fields. In these fields, engineers use different high-speed PCB design strategies, which involve over-design strategies of simulation and analysis. In the field of telecommunications, the design is very complicated, and the transmission speed in data, voice and image […]

After importing the design data, the PCB design engineer will start the PCB layout design. The quality of layout often determines the success or failure of veneer. What are the layout problems we encountered in those years? Have you laid out the layout and found that there is no room for punching holes? The extra […]

First, the structure and types of metal-based copper clad laminate Metal-based copper clad laminate is generally composed of three parts: metal substrate, insulating dielectric layer and conductive layer (generally copper foil), that is, one or both surfaces of the treated metal substrate are covered with insulating dielectric layer and copper foil, which are compounded by […]

Now there are more and more electronic devices, and many things are developing in the direction of intelligence, which requires more circuit boards to undertake the control systems of these devices. Here’s how to choose PCBA processing technology for circuit board processing. How to correctly select PCBA processing technology for processing circuit board 1. single-sided […]

In the process of PCB design, some engineers don’t want to lay copper on the bottom of the surface layer in order to save time. Is this the right thing to do? Is it necessary to lay copper on the surface layer of PCB? First of all, we need to be clear: it is beneficial […]
