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
Common mistakes in PCB design process are summarized as follows: 1. Pad overlap; 2. Non-standard use of graphic layer; 3. Characters unreasonable, 4. Single side pad set aperture, 5. Use filler block to draw pad, 6. The electric stratum is designed with b
Pad can be divided into 7 categories, according to the shape of the distinction is as follows: 1. Square pad,2. Round pad,3. Island pad,4. Teardrop pad,5. Polygon pad,6. Oval pad,7. Open pad
How to cleverly design multiple circuits of the same circuit structure quickly: 1. Design code segments (code segments), 2. Equipment Table, 3. Multi-channel design method (Multi-channel)
What is PCB design: PCB design is based on the schematic diagram of the circuit to achieve the function required by the circuit designer. PCB design mainly refers to layout design, which needs to consider the layout of external connections. Optimized layo
PCB design differential wiring operation skills: 1, activate the wiring instruction, 2, support single line Mode, 3, in the layout of small space position differential wiring, can switch to the Neck Mode, 4, according to the wiring needs to select the app
Copper coating on PCB board, if the grounding problem is handled well, is certainly "more advantages than disadvantages", it can reduce the signal line backflow area, reduce the signal external electromagnetic interference
Shielding method in high frequency PCB design: the twisted pair in data twisted pair can resist external interference and cross-talk between pairs through its own twisting at low frequency, but at high frequency, only twisting and merging can not achieve
What is the cause of PCB board broken line: 1, film process: 2, exposure process: 3, development process: 4, etching process: 5, electroplating problem: 6, improper operation
When the field strength of electromagnetic field exceeds a certain limit and the operation time is long enough, it may endanger human health. It can also interfere with other electronic devices and communications. All of these need to be protected.
New design PCB board to find the fault method: 1. Voltage measurement method, 2. Signal injection method, 3. See, hear, smell, touch
Factors related to EMC issues in PCB design: 1. System design: 2. Structural impact: 3. Cable influence: 4. Component selection: 5. Related to SI/PI simulation: 6. Grounding, 7.PCB design relationship, 8. Software anti-jamming technology: 9. Shielding: 10
