PCBs designed for high-frequency applications, especially those operating at GHz signals, require careful attention to layering design to ensure signal integrity. A well-planned PCB layering for GHz signals minimizes signal loss, controls impedance, and reduces crosstalk. In this comprehensive guide, we will explore the key points of high-frequency PCB layering, advanced materials, and techniques to … Read more
Click the blue text / Follow usBackground Introduction Content Summary: In high-speed PCB design, engineers need to apply precise routing rules to specific network groups (such as differential pairs, DDR data lines, etc.) to ensure signal integrity. However, when networks are segmented by series components (such as resistors and capacitors), traditional constraint rules cannot be … Read more
1. Manual Routing Whenever Possible Generally speaking, most PCB design software includes an auto-routing feature, but in reality, no auto-router can completely replace the skills, experience, and flexibility of a PCB Layout Engineer. (Kudos to manual PCB Layout Engineers) In some cases, you can use auto-routing: After placing all components, you can use auto-routing to … Read more
Back drilling is a commonly used process technology in the manufacturing of printed circuit boards. It involves drilling out a portion of the via from either side to a predetermined depth, thereby shortening the total length of the via. The goal is to achieve more blind and buried via structures with the least number of … Read more
When starting a new design, we often spend most of our time on circuit design and component selection, and during the PCB layout and routing phase, we may overlook important considerations due to lack of experience.If sufficient time and effort are not allocated to the PCB layout and routing phase, it may lead to issues … Read more

Which Multilayer PCB Manufacturer is the Best? In the electronics industry, PCBs (Printed Circuit Boards) serve as the “skeleton” and “nervous system” of electronic devices, providing mechanical support and electrical connections for components. With the rise of technologies such as 5G communication and artificial intelligence, the demand for multilayer PCBs has surged, especially in high-frequency … Read more
In high-speed circuit design, we often hear a term—impedance matching. Especially in high-layer PCB designs, impedance control is almost an unavoidable topic. So, why is impedance matching necessary for high-layer PCBs? Today, we will discuss this “invisible killer” that engineers are concerned about. 🚀 Why is Impedance Matching Important? In low-speed signal circuits, wires behave … Read more
The chassis is made of metal, with a screw hole in the middle, which connects to the ground. Here, a 1M resistor is connected in parallel with a 1nF capacitor to the circuit board ground. What are the benefits of this configuration?In metal chassis devices, the PCB GND (signal ground) is connected to the chassis … Read more
