Ask three engineers what limits a Microwave PCB design and you will hear three different answers. Ask them about copper surface roughness and the conversation usually converges, because it is one of the few parameters that touches every stage of the build. The practical difficulty is that copper surface roughness is not set in one...
On paper, a High-Speed PCB, is a set of dimensions and a bill of materials. In production it is a process, and Dielectric Constant is where the two views meet. Small deviations that no one would question on a low-frequency board become measurable at microwave bands. Most of the cost associated with dielectric constant (Dk)...
Why PCB Material Characterization Matters at High Frequencies The electrical properties of a PCB material can be characterized using several different measurement techniques. Some methods directly evaluate the dielectric material using specialized fixtures, while others characterize the material through an actual circuit structure. This distinction becomes increasingly important as PCB operating frequencies move from conventional...
Why Material Selection Matters in Millimeter-Wave PCB Design Millimeter-wave technology was once considered too expensive or technically difficult for widespread commercial applications. Today, that has changed rapidly. The expansion of 5G New Radio (5G NR), 77 GHz automotive radar, ADAS, high-speed wireless communication, RF modules, and advanced sensing systems has made millimeter-wave PCB technology increasingly...
As operating frequencies continue to increase, signal loss becomes one of the most important design challenges in high-frequency and millimeter-wave PCB applications. At frequencies such as 24 GHz, 60 GHz, and 77 GHz, even relatively small dielectric losses, conductor losses, impedance discontinuities, and material variations can significantly affect signal integrity. This has made low-loss PCB...
As RF, microwave, and high-speed communication technologies continue to evolve, partnering with a reliable high frequency PCB OEM is critical for companies seeking consistent performance, stable quality, and scalable manufacturing. High frequency PCBs operate at GHz and millimeter-wave ranges, where even small variations in materials or processes can significantly impact signal integrity. This article explains...
