In circuit board design, we are usually very concerned about the quality of the signal, but sometimes we usually limit the research on the signal line, and the power and ground as the ambition of the situation to deal with, although this can make the ques
For those devices that are easy to produce noise, small current circuits, large current circuit switching circuits, etc., should try to keep it away from the logic control circuit and storage circuit (ROM, RAM) of the single chip computer, if possible, th
Through the above analysis of the parasitic characteristics of the hole, we can see that in high-speed PCB design, seemingly simple holes often bring great negative effects to the design of the circuit.
To sum up, to choose an excellent PCB design company, you need to consider the strength of the company, customer reputation, service quality and price, after-sales service and other aspects. In the selection, you can according to their actual needs and bu
Surface mount testing can effectively test surface-mount components on the circuit board, such as chips, capacitors, resistors, etc. In addition, when performing surface mount tests, it is also possible to check whether the solder joints on the circuit bo
The production process and chemical solution of different PCB design manufacturers are still very different. Before the design of the wastewater treatment project, participate in the waste water diversion work of PCB board design and production, and verif
High frequency circuit PCB design is a complex process, involving many factors, may be directly related to the performance of high frequency circuit.
Analog circuits use star ground. The current consumption of audio power amplifiers is usually large, which can have an adverse effect on their own grounding or other reference grounding.
PCB assembly, do not apply any solder on the top or bottom pad. Use screws with built-in washers to achieve tight contact between the PCB and the metal case/shield or ground surface bracket.
the idea that thin films can be used to give mechanical strength or adequate insulation to individual parts inserted into printed circuit boards is wrong. The components must be mechanically inserted and must have their own suitable caulking agent, so tha
Differential PCB lines are usually always routed in pairs, and the distance between them along the direction of the pair remains a constant at any position. In general, the layout of the differential pair is always as close as possible.
Now PCB design time is getting shorter and shorter, smaller and smaller board space, higher and higher device density, extremely demanding layout rules and large-size components make the designer's job more difficult.
