(Above) In the production workshop of Yongqiang Technology, staff combine electronic-grade copper foil, prepreg, and steel plates, sending them into the press for lamination. As a primary functional material for electronic device motherboards, high-frequency and high-speed copper-clad laminates act like a precise “nervous system,” bearing the responsibility for information transmission in fields such as 5G … Read more
Pengding Holdings has disclosed a flexible circuit board and its manufacturing method. The core innovation of this circuit board lies in the adoption of a unique dielectric structure, which uses air filled in a closed cavity as the primary medium surrounding the signal transmission lines. Compared to traditional dielectric materials, air has a lower dielectric … Read more

The patent discloses a design for flexible circuit boards intended to reduce high-frequency signal transmission losses by introducing air-filled sealed cavities to minimize dielectric … Read more
1. What is a Dielectric? A dielectric refers to a substance or space that can transmit force, energy, or information under specific conditions. In physics and engineering, dielectrics typically refer to solids, liquids, or gases that can transmit mechanical waves, electromagnetic waves, etc. For example, in acoustics, air, water, and solids can serve as media … Read more
Editor’s Note: The content of this article is quite concise. The first two factors are introduced using ADS simulation schematics, and those interested can follow along. Many buses have requirements for loss, so for design engineers, it is essential to understand which factors dominate the changes in loss. We often discuss the issue of loss … Read more
