Substrate Material DiversityThe miniaturisation and integration of microwave devices have imposed higher demands on […]

RF connectors are electrical connectors used for transmitting radio frequency signals. They are also referred to as coaxial connectors within the industry, as RF connectors are typically connected to coaxial cables and also have a coaxial structure. Classification of RF connectors:By connection interface structure:Threaded connection: Uses series such as SMC, SMA, TNC, N, UHF, 7/16,

Microstrip patch antennas and their arrays may not be seen much but are the most widely used form of antenna. They are simple in structure and can be formed by a dielectric, a metal conductor patch on top of the dielectric, and a ground plane. Even the intervening dielectric can be an air structure. The

High frequency pcb is special circuit board dedicated to higher electromagnetic frequencies, applicable to high-frequency (frequency over 300MHz and wavelength less than 1 metre) and microwave (frequency higher than 3GHz, wavelength less than 0.1 metre) fields. This type of PCB is usually in the microwave substrate copper-clad board, through part of the use of ordinary

What is a high-Tg PCB? What are the advantages of using high Tg PCBs? When the temperature of a high Tg printed circuit board rises to a certain range, the substrate transitions from a ‘glass state’ to a ‘rubber state,’ and this temperature is referred to as the board’s glass transition temperature (Tg). In other

What is 94v-0 on a pcb? The 94v-0 standard is a standard set for the combustion characteristics of plastic materials in electronic and electrical products. It was established by Underwriters Laboratories (UL), a highly authoritative insurance laboratory in the United States. This standard specifies the specific behaviour of plastic materials when exposed to flames, with

The trend in PCB design is moving towards lighter, thinner, and smaller boards. In addition to high-density circuit board design, there is also the important and complex field of three-dimensional connection assembly for rigid-flex circuit boards. Rigid-flex boards are also known as rigid-flexible boards. With the emergence and development of FPC circuit boards, rigid-flex circuit

An integrated circuit socket, also known as an IC socket, is an interface used to connect integrated circuits. It allows integrated circuits to be easily inserted and removed, facilitating testing and replacement. This type of socket is widely used in various electronic devices, particularly those that require frequent replacement or testing of integrated circuits. An

Rogers 5880 sheet is a high performance PTFE composite material with extremely low dielectric constant and loss, widely used in high frequency circuits for communications, automotive, aerospace and other applications. Sheet Parameters:Rogers 5880 sheet is a polytetrafluoroethylene (PTFE)-based material with a dielectric constant of 2.2 and thicknesses ranging from 0.003‘ to 0.240’. The sheets are

In the context of the rapid development of 5G communication technology, the performance of high-frequency PCB board has become the key to ensure the quality of signal transmission and system stability. Traditional FR4 materials are widely used in all kinds of electronic products for their excellent cost performance, while Rogers and other high-frequency specialised materials

Rogers RO4350B dielectric constant stability is relatively high, the standard value using 10GHz frequency test value of 3.48, with the frequency increase in dielectric constant will decline, 24GHz frequency dielectric constant compared to the 10GHz frequency decreased by 0.01, for 3.47. Rogers RO4350B high-frequency board is fully compatible with traditional PCB manufacturing technology, do not

Battery on pcb is battery devices that are mounted on circuit boards to provide electrical support for electronic components, chips, etc. on the circuit boards. Battery on pcb is usually selected based on size, voltage and capacity requirements, and the following are the 5 most common types: The Role of Battery on pcb How to

Dev Board (Development Board) is a hardware prototyping platform for embedded system design, usually integrating processor, memory, peripheral interfaces and other modules for software debugging, algorithm verification or product prototyping. According to different core architectures, they are mainly divided into the following three categories: Using a dev board as a development tool for embedded system

Eutectic soldering, also known as low melting point alloy soldering, is a specific soldering technique. The process involves the removal of unstable oxide layers at the interface between the chip and the gold-plated base by gentle friction at specific temperatures and pressures, which causes the contacting surfaces to melt and form a liquid phase. Subsequently,

LED driver board is used to drive the LED lamps and lanterns circuit board, its main function is to convert the power supply to the current and voltage suitable for the LED work.LED driver board has the characteristics of high efficiency, stability and reliability, can provide constant current output, to ensure that the LED lamps

PCB encapsulation materials consist of substrates, interconnections, frames, interlayer media, and sealing materials. Among these, PCB encapsulation substrate materials serve as electronic components, primarily providing mechanical support, hermetic protection, and facilitating heat dissipation for electronic components and their interconnections.Substrate: High-density multilayer encapsulation substrates primarily serve as an electrical transition between semiconductor chips and conventional PCBs

Welding porosity is a common defect encountered in welding production, formed by the absorption and release of gases (primarily oxygen, nitrogen, and hydrogen) within the weld seam. It not only reduces the effective cross-sectional area of the welded component but also causes stress concentration, significantly lowering the strength and toughness of the weld metal. This

What is a dipole antenna? A dipole antenna is a basic antenna used to broadcast radio frequencies. A dipole antenna is named after the two conductors of equal length that extend from either side of the antenna. A dipole is an omnidirectional antenna, which means that it broadcasts frequencies in all directions at the same
