How to solve the "signal integrity" problem in PCB design?

88 0 Aug 12.2024, 16:31:48

Answer:Signal integrity issues affect the circuit boards performance and data transmissions reliability. Here are some ways to solve signal integrity issues:High-speed signal routing: Design dedicated routing channels for high-speed signals and minimize the length and turns of signal lines.Impedance matching: Make sure the impedance of the signal line matches the impedance of the PCB to reduce signal reflection.Differential signal: Use differential signal line pairs to improve the signals anti-interference ability.Reduce crosstalk: Keep high-speed signal lines away from low-frequency signal lines and use ground isolation to reduce crosstalk.Terminal resistance: Add appropriate terminal resistance at the end of the signal line to avoid signal reflection and distortion.

Discussion on how to process high-speed signals and avoid interference in PCB embedded systems

70 0 Aug 11.2023, 13:33:08

Hello everyone, recently I am designing a PCB embedded system, which involves some high-speed signal processing, but I am a little confused about signal interference and timing. I would like to ask my predecessors, what is the best way to effectively process high-speed signals while avoiding signal interference and timing problems?

What tests are required for PCBA circuit boards?

PCB and PCBA are the cornerstones of electronic products. In order to improve the yield rate, circuit board manufacturers spare no effort to improve the board manufacturing process, and also use various professional testing instruments to find product defects.The English of PCB is the abbreviation of Printed Circuit Board, which is often called bare board or bare board in the industry. It is an important component, a support for electronic components, and a carrier for electrical connection of electronic components.PCBA, even if PCB+components are assembled, refers to the circuit board obtained by the PCB light board after SMT loading and then through DIP plug-in. Generally speaking, it is a circuit board after installing components such as resistors, integrated circuits, and capacitors.SMT surface mount technology mainly uses the placement machine to mount some tiny parts on the PCB board. The production process is: PCB board positioning, printing solder paste, placement machine place...
