HDI is smaller and lighterThe HDI board is made of the traditional double-sided board as the core board through continuous lamination. This kind of circuit board made by continuous layering is also called build-up multilayer board (Build-up Multilayer, BUM). Compared with traditional circuit boards, HDI circuit boards have the advantages of “light, thin, short, and …
Electrical safety distance1. Spacing between wiresAs far as the processing capabilities of mainstream PCB manufacturers are concerned, the minimum distance between wires should not be less than 0.075mm. The minimum line spacing refers to the minimum distance from the board line to the line and from the line to the pad. From a production point …

1. Market sizeAs an important source of information interaction and perception in the era of the Internet of Things, smart sensors are an important pole of the future sensor market. From the perspective of the size of the smart sensor market, in terms of global statistics, according to statistics, the global smart sensor market is …
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 …
