Research on Manual Routing Design of High Frequency PCB

Posted on January 22, 2019 by G

Routing is the overall requirement for high-frequency PCB design based on a reasonable layout. Wiring includes both automatic routing and manual routing. Generally, regardless of the number of critical signal lines, these signal lines are manually wired first. After the wiring is completed, these signal lines are carefully inspected, fixed after inspection, and then automatically routed to other wirings. That is, the combination of manual and automatic wiring is used to complete the wiring of the PCB.

Research on Manual Layout Design of High Frequency PCB

Posted on January 22, 2019 by G

Although Protel99SE has the function of automatic layout, it can not fully meet the working needs of high-frequency circuits. It is often necessary to rely on the designer's experience. According to the specific situation, the manual layout method is used to optimize the position of some components, and then combined with automatic layout. Complete the overall design of the PCB. The rationality of the layout directly affects the life, stability, EMC (electromagnetic compatibility) of the product, etc., must be from the overall layout of the circuit board, the feasibility of wiring and the manufacturability of the PCB, mechanical structure, heat dissipation, EMI (electromagnetic Comprehensive considerations such as interference), reliability, and signal integrity.

Balanced PCB stack design method

Posted on January 22, 2019 by G

Designers may design odd-numbered printed circuit boards (PCBs). If the wiring does not require an extra layer, why use it? Isn't reducing layers not making the board thinner? If the board is one less layer, is the cost lower? However, in some cases, adding a layer will reduce the cost.

Finding software defects during PCB design

Posted on January 21, 2019 by G

This article will show you how to avoid those hidden but common mistakes, and introduce a few tips to help engineers discover hidden errors in PCB copy board software. Most software development projects rely on code inspection, structural testing, and functional testing to identify software defects. Although these traditional techniques are very important and can find most software problems, they cannot detect many common errors in today's complex systems.

PCB design principles and anti-interference measures

Posted on January 21, 2019 by G

PCB is a support for circuit components and devices in electronic products. It provides electrical connections between circuit components and devices. With the rapid development of electricity technology, the density of PGB is getting higher and higher. PCB design has a great impact on the ability to interfere with interference. Therefore, when designing PCBs. The general principles of PCB design must be followed and should meet the requirements for anti-interference design.

Detailed manual layout and routing using flying leads in PCB design

Posted on January 11, 2019 by G

Whether the wiring of a printed board can be completed smoothly depends mainly on the layout, and the higher the density of the wiring, the more important the layout. Almost every designer has encountered such a situation. When there are only a few wires left, they find that they can't be laid out anyway. They have to delete a lot or all of the wiring and re-adjust the layout! A reasonable layout is guaranteed. The premise of wiring.

Signal Integrity: Reflections from changes in PCB trace width

Posted on October 30, 2025 by G

When PCB layout is performed, it often happens that when a trace passes through an area, due to the limited wiring space of the area, thinner lines have to be used, and after passing through this area, the line is restored to its original width. A change in the width of the trace causes a change in impedance, so reflection occurs and affects the signal. So under what circumstances can this effect be ignored, and under what circumstances must we consider its impact?
