Definition of High-Frequency PCB High-frequency boards refer to special circuit boards with electromagnetic frequencies that are relatively high, used in the fields of high frequency (frequency greater than 300MHz or wavelength less than 1 meter) and microwave (frequency greater than 3GHz or wavelength less than 0.1 meter) PCBs. They are produced using standard rigid circuit … 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
In the manufacturing of modern electronic devices, printed circuit boards (PCBs) are crucial components. The design of PCBs involves many factors, among which the characteristics of PCB materials are one of the key factors determining the performance and reliability of the circuit board. Different PCB materials exhibit different behaviors in thermal, mechanical, and electrical aspects, … Read more
