Today’s mass-produced electronic hardware is manufactured using well-known surface mount technology or SMT. There is no reason! In addition to providing many other advantages, SMT wireless charging board S for mobile phones still has a long way to go in speeding up the production speed of wireless charging board for mobile phones. SMT（Surface Mount Technology） […]

PCB design engineers may design odd-numbered printed circuit boards (PCBs). If wiring doesn’t need an extra layer, why use it? Won’t reducing layers make the circuit board thinner? If the circuit board is one less layer, isn’t the cost lower? However, in some cases, adding one floor will reduce the cost. There are two different […]

Multi-CPU parallel computer technology has greatly improved the computing speed of the system, breaking through the limit of single CPU processing speed. At the same time, the single-board computer design with multiple CPUs can reduce the volume of the computer system, the development cost and the development cycle of the system. 1. Hardware design of […]

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 […]

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 […]

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 […]

In a grounded desktop product, when the ESD contact discharge test with a test voltage of 6KV was conducted at the grounding terminal, the system was reset. In the test, try to disconnect the grounding terminal from the Y capacitor connected to the internal digital working ground, but the test result has not improved significantly. […]

In the process of PCB outsourcing design, especially in high-frequency circuit design, some irregular and abnormal phenomena caused by ground wire interference are often encountered. In this paper, the causes of interference caused by ground wire are analyzed, three types of interference caused by ground wire are introduced in detail, and solutions are put forward […]

1 Why do you want to divide digital ground and analog ground? Although it is interlinked, it is different when the distance is long. The voltage at different points of the same wire may be different, especially when the current is large. Because there is resistance in the wire, the voltage drop will occur when […]
