High Speed PCB Design

High-speed PCB design guidelines



In the PCB design, it is generally considered that if the frequency of the digital logic circuit reaches or exceeds 45MHZ~50MHZ, and the circuit operating above this frequency has already occupied a certain amount (for example, 1/3) of the entire electronic system, then it is called high speed circuit.



High-speed PCB design is developed with large-scale improvements in system design complexity and integration, because when the system is operating at 50MHz, transmission line effects and signal integrity problems will occur, and when the system is operating up to 120MHz unless high speed is used. Circuit design knowledge, otherwise the PCB based on the traditional method design will not work. Therefore, high-speed circuit design technology has become a design method that electronic system designers must adopt.

High-Speed PCB Design in Hitech Circuits



High-speed printed circuit board design is a process of balancing the circuit design requirements, device technologies, and fabrication materials and methodologies, to deliver a PCB that can transfer signals between the components, with integrity.



After many years of research and practice, Hitech Circuits can well meet the requirements of high-speed PCB design. We can provide you with high-quality, fast PCB design for high-speed, high-density, digital-analog hybrid, and PCB design of new processes and new technologies (such as flexible boards, HDI PCB, buried blind holes, etc.). We have a group of high-quality PCB design engineers in Shenzhen. We have rich experience in carrier-class high-speed multi-layer circuit board PCB design. We comprehensively consider timing requirements, stripline and microstrip, signal matching scheme, Signal quality, signal trace topology, power ground decoupling, high-speed signal return current return path signal impedance control and stack stackup control, single-board EMC/EMI policy analysis, blind via and buried via and so on, and from the perspective of high-speed pcb layout, use our experience to optimize your schematic design so that your board's inherent quality is higher and the operation is more stable.



Are your PCB Layout High-Speed?



More and more PCBs combine multiple circuits. Your PCB doesn’t have to clock at gigahertz to be high-speed – and to add to that, technologies like IOT and smart home controllers are growing exponentially.



Even using standard components like DDR3, DDR4 or DDR5 SDRAMs means following high-speed PCB design guidelines. You need to constrain your PCB layout to achieve top-class signal integrity – so it works properly – but also so your product is the best it can be.



eCADSTAR isn’t the only solution that lets you do that. The difference is in the way it’s all built-in, not an afterthought – and its unrivalled ability to work with the complex detail you need for ultra-critical layout.
