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,

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
A transistor is an electronic device with three terminals used to amplify or switch electronic signals. Its basic components are two semiconductor materials with opposite properties (called p-type and n-type), usually silicon. Typically used as a semiconductor device for amplifiers or electronically controlled switches, the transistor is the basic building block for regulating the operation
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
Patch antenna is a commonly used antenna for wireless communication and is widely used in many small electronic devices. It has the advantages of miniaturisation, easy fabrication, easy integration and higher operating frequency band. The principle of patch antenna is based on electromagnetic induction and electromagnetic radiation. It is made of a metal sheet, which
A current divider, also known as a current shunt, is a component used to distribute current to support multiple circuits. It divider current from one circuit to multiple branch circuits, each of which can have a different resistance value as needed. Current divider key characteristics: Current divider is based on the principle of DC current
PCB shield cover is a component used to protect the internal components of electronic equipment from electromagnetic interference, generally used in places where it is necessary to prevent the leakage of radiation signals or to avoid the impact of external electric fields, such as communications equipment and computer motherboards commonly used on the PCB board
