High-Frequency PCB: A High-Speed Circuit for Signal Transmission

Are you a technology that handles navigation signals or a wireless network? One of the most important features in these devices is the high frequency PCB. These circuits are also important in electronics as telephones because they are the ones responsible for transmitting data. We looked at these pcbs in detail below, including their high-frequency design, so read on to learn more.

What is a High Frequency PCB?

High-frequency printed circuit boards are electronic devices used to transmit high-frequency frequencies with a frequency range of between 500mhz to 2ghz.

Since the circuit board has a fast flow signal and a high signal sensor, manufacturers build them using high-frequency laminate materials. This ultimately lowers the dissociation factor and stabilizes the dielectric constant.

路         They Make Up High Frequency pcbs

路         Low and stable Dk (Dielectric Constant)

路         Diki Df (Dissipation Factor)

路         Extremely hot

路         Impact endurance

路         Chemical resistance

路         Remove denial

路         Deep water drowning

路         Like heat transfer to copper foil

路         Low dimensional stability

路         Perfect board spacing

Tools Used for High Frequency pcbs

The high frequency pcb supplier boards require special PCB material to produce a high-speed signal output. Some of these unique features include:

路         FR4: It is inexpensive laminate material and easy to manufacture. As such, it has limited electrical performance, especially if the signature speed exceeds 1.6ghz.

路         Rogers 4350B HF: Like the Fr4, this model has a low manufacturing cost, competitive price, and offers high-quality stability.

路         ISOLA IS620 E-fiberglass: Although difficult to manufacture, this material provides excellent thermal insulation and electrical performance.

路         Taconic RF-35 Ceramic: This is a low-density PTFE-filled ceramic with woven glass. They are moderate in design but have good peeling power, good electrical performance, and low power consumption.

路         Taconic TLX: Includes PTFE fiberglass, TLX is a compact composite that has excellent mechanical, thermal, and electrical properties. As a result, it is difficult to design.

路         Rogers RO3001: The bonding film has a low loss tangent and dielectric constant. It is also resistant to chemicals and extreme heat.

路         Rogers RO3003: The RO3003 has PTFE glass material which offers low Dk loss and low cost.

路         ARLON 85N: Pure polyamide resin with high heat resistance

路         Different manufacturers offer different types of high-frequency applications, but in general, they can be:


路         Ceramic-filled PTFE

路         PTFE and woven glass

路         Ceramic-filled hydrocarbon

路         PTFE contains micro-glass fiber

路         Ceramic-filled hydrocarbon with woven glass

路         Ceramic-filled PTFE with woven glass
