Design aspect:(1) Expansion and contraction coefficient matchingGenerally, a large-area copper foil is designed on the circuit board for grounding, and sometimes the Vcc layer is also designed with a large-area copper foil. When these large-area copper foils cannot be evenly distributed on the same circuit board When it is on the board, it will cause …
Design standards for the shape and size of PCB pads1. Call PCB standard package library2. The minimum single side of the pad is not less than 0.25mm, and the diameter of the entire pad is not greater than 3 times the aperture of the component3. Try to ensure that the distance between the edges of the two …
The ubiquity of PCBs in our daily lives continues to expand, and this growth is largely driven by consumer demand for smarter products that can monitor or control more common activities in which we engage, as well as industry demand . For example, in aerospace, medical devices, automotive, and commercial electronics, industry needs include enhanced …
Hardware circuit designers need to follow certain steps when designing circuits. You know, working strictly in accordance with the steps is a necessary prerequisite for designing a perfect circuit. For general PCB circuit design, the process is mainly divided into the following three steps: 1. Design circuit schematic diagram At the beginning of circuit design, …
1. The design of the physical board frame must pay attention to the precise size, avoid installation troubles, and ensure that the circuit board can be smoothly installed into the chassis, shell, slot, etc. 2. It is better to use rounded corners (such as the four corners of the rectangular plate). On the one hand, …
A . About PCB PCB is the abbreviation of printed circuit board. It is an important electronic component in the electronics industry, a support for electronic components, and a carrier for electrical connections of electronic components. The PCB of the circuit board factory is widely used in the production and manufacture of electronic products, and its …
The 4G/5G protocol processing platform has the protocol processing capabilities of 4G base station (eNB), 5G base station (gNB), 4G core network (EPC), and 5G core network (5GC). Independent networking mode, supports commercial 4G/5G terminal access, supports FDD and TDD, base station bandwidth supports 20/40/50/60/80/100MHz multiple modes, data subcarrier spacing supports 15kHz, 30kHz, 120kHz, protocol …

Reasons for laying copper:1. EMC, for large-area ground or power supply copper, it will play a shielding role, and some special ones, such as PGND, will play a protective role.2. PCB process requirements, generally in order to ensure the effect of electroplating, or lamination without deformation, copper is laid on the PCB layer with less …

What are the process flow of PCB manufacturing? PCB circuit boards are used in almost all electronic products, ranging from watches and earphones to military and aerospace applications. Although they are widely used, most people do not know how PCBs are produced. Next , let us learn about the PCB manufacturing process and production process! …
Since every switching power supply generates broadband noise, it is even more difficult to integrate the DC/DC converter in the automotive circuit board network into the automotive control device while meeting the EMC standards of the automotive OEM. . Typically, noise from DC/DC converters and other high-speed circuits propagates and radiates through the connecting cables …
Impedance matching means that when energy is transmitted, the load impedance is required to be equal to the characteristic impedance of the transmission line. At this time, the transmission will not produce reflection, which means that all energy is absorbed by the load. On the contrary, there is energy loss in transmission. In high-speed PCB …
For electronic equipment, a certain amount of heat will be generated during work, which will cause the internal temperature of the equipment to rise rapidly. If the heat is not dissipated in time, the equipment will continue to heat up, and the device will fail due to overheating. The reliability of electronic equipment Performance will …
