Electronic devices with high frequency are a developing tendency nowadays, especially in wireless networks. Satellite communication growing rapidly, and information products move towards high speed and high frequency. Thus developing new products always need to use high-frequency substrates, satellite system, mobile telephone receiving base station, and so on, these communication products must use high frequency PCB.
High-frequency PCBs usually provide a frequency range from 500MHz to 2 GHz, which can meet the needs of high-speed PCB designs, microwave, radiofrequency, and mobile applications. When the frequency is above 1 GHz, we can define it as high frequency.
The complexity of electronic components and switches is continually increasing nowadays and needs faster signal flow rates. So, higher transmission frequencies are required. High-frequency PCBs help a lot when integrating special signal requirements into electronic components and products with advantages like high efficiency, fast speed, lower attenuation, and constant dielectric properties.
How to choose the right material for high frequency PCB?
There are many aspects to consider when selecting a high frequency PCB board and its corresponding type of PCB connector, including dielectric constant (DK), dissipation, loss and dielectric thickness.
The most important of these is the Dk of the relevant material. Materials with a high probability of dielectric constant change often experience impedance changes that disrupt the harmonics that make up the digital signal and cause an overall loss of digital signal integrity – one of the things high frequency PCBs are designed to prevent.
All in all, because of the performance benefits, high-frequency PCBs have been widely used in High-speed and high-density PCB designs. Anyway, you also should consider that high-frequency materials are more expensive than ordinary materials. It would be best to consider the actual needs of your PCBs and make a wise decision.
PRINTED CIRCUIT BOARD PROTOTYPE
The printed circuit board (PCB) is the foundation of every electronic device in the world today. The versatility of high-tech products determines the complexity and high performance of the PCB.
The PCB prototype is an indispensable step before a new product enters mass production. The PCB prototype can correct design defects and improve design performance at a lower cost and faster speed. In addition, it helps to avoid more problems and reduce risks in mass production. Below JHD will walk you through everything you need to know about PCB prototyping.
Why is PCB prototyping so important?
The two most critical points of a fast PCB prototype are speed and quality. Create a prototype board before the new PCB products are invested in large-scale production to ensure the complete implementation of the PCB prototype design. JHDPCB always follows and executes IPC Level 2 & 3 quality standards to ensure that you provide you a reliable and fast PCB prototyping customization service. Good PCB prototype design can bring you the following help:
- Before large-scale commissioning, the early design defect was detected. Avoid large-scale bad products;
- Provide the working principle of a detailed PCB circuit board;
- Test multiple designs efficiently in a more economical way;
