The performance index of high frequency circuit directly affects the quality of the whole product. The layout and wiring of components can maximize the performance index of the circuit and achieve the design purpose of anti-interference.
Circuit board design and production process: 1. Preparation of production materials, 2. Circuit board production and manufacturing, 3. Production and design
Preliminary work to be done before PCB design :1, determine the number of PCB layers, 2, PCB design rules and restrictions, 3, component layout
Spacing is more important in high voltage designs because the voltage across the board components makes arcing between the two conducting components more likely to occur on your PCB. Any electric arcs that do occur pose a higher risk to both the product a
When selecting circuit board components based on component packaging, the following needs to be considered: component packaging selection. Grounding methods. Virtual component packaging. Verify complete material list data. Sort. Excess gate circuit.
How to do electromagnetic compatibility design :1. Suitable wire width,2. Key points of component wiring,3. Wiring rules for high frequency and high speed signals
SMT SMT processing technology has the advantages of: first, high reliability, strong vibration resistance, second, small size of electronic products, high assembly density, third, high frequency characteristics, reliable performance, four, improve product
When the overshoot is serious, the protection diode will fail prematurely because of its work. Severe downstrokes can cause false clock or data errors (misoperation)
Generally, there are several ways to deal with analog ground and digital ground: 1, directly separate,2, digital ground and analog ground connected with magnetic beads; 3, digital and analog ground with capacitor connection, using the principle of capacit
In the study, it is found that PCB design mainly has four aspects of interference: power supply noise, transmission line interference, coupling and electromagnetic interference
The public power cables and ground cables on the two-sided SMB should be placed near the edge of the SMB and on both sides of the SMB. The power layer and ground cable layer can be installed at the inner layer of the multi-layer SMB, and the cables, power
PCB layout skills: 1, arrange the position of each functional circuit unit according to the circuit flow, so that the layout is convenient for signal flow, and make the signal as far as possible to maintain the same direction, 2, the core components of ea
