How to choose PCB substrate? In recent years, the printed circuit board market has shifted from traditional hardware products such as desktop computers to wireless communications such as servers and mobile terminals. The mobile communication equipment represented by smart phone promotes PCB to develop towards high-density, lightweight and multi-function. Printed circuit technology cannot be implem...
The rapid development of science and technology determines that all enterprises need to improve, and PCB depends on science and technology, so it is natural not to lag behind. Therefore, the layout of high-frequency PCB has become the key point that we need to discuss when designing PCB high-frequency board. Today, we sorted out the key points you need to pay attention to in the layout of high-fre...
1. An uWB monopole antenna based on four-layer printed circuit board (PCB) is designed based on the method of resonance of multiple radiating patches in different frequency bands. The antenna is fed by microstrip and has two patches of different sizes on two different planes of the dielectric substrate. In order to realize the miniaturization of the antenna, a multilayer uwb monopole antenna with ...
Rogers TMM6 Microwave high frequency board material has isotropic dielectric constant (Dk). Like other TMM series materials, Rogers TMM 6 combines many of the desirable properties of ceramic and PTFE substrates and utilizes simple flexible plate machining techniques. Rogers TMM 6 Thermosetting MICROWAVE HF board materials are designed for ribbon-line and microstrip line applications with high reli...
Generally speaking, high frequency can be defined as the pre-rate above 1GHz. The most commonly used high-frequency circuit board substrates are fluorine-based dielectric substrates. For example, polytetrafluoroethylene (PTFE) is usually called Teflon, which is usually used above 5GHz. , In addition, FR-4 or PPO substrate is also used, which can be used for products between 1GHz-10GHz. The physica...
Basic Knowledge of FPC Flexible Circuit Board With the continuous increase of the production ratio of flexible PCB and the application and promotion of rigid flexible PCB, it is now more common to add flexible, rigid or rigid flexible PCB to say how many layers of FPC it is. Generally, FPC made of soft insulating material is called soft FPC or flexible FPC, rigid flexible compound PCB called rigid...
