IC packaging refers to the process of connecting circuit pins on a silicon chip to external connectors with wires for connection with other devices. Packaging form refers to the outer shell used for installing semiconductor integrated circuit chips. It not only plays a role in installation, fixation, sealing, protecting the chip, and enhancing the electric heating performance, but also connects to the pins of the packaging shell through the contacts on the chip using wires. These pins are connected to other devices through wires on the printed circuit board, thus achieving the connection between the internal chip and external circuits. Because the chip must be isolated from the outside world to prevent impurities in the air from corroding the chip circuit and causing a decrease in electrical performance.
Radio frequency tags generally refer to radio frequency identification technology. The principle is non-contact data communication between the reader and the tag to achieve the goal of identifying the target. RFID has a wide range of applications, typical of which include animal chips, car chip anti-theft devices, access control, parking lot control, production line automation, and material management.
Fingerprint recognition is the process of classifying and comparing the fingerprints of the identified object for discrimination. Fingerprint recognition technology, as one of the biological feature recognition technologies, has gradually matured in the new century and entered the field of human production and life.
The driving power supply is a voltage converter used to convert the power supply into a specific voltage and current to drive LED lighting. It is a key component of LED lighting and plays a crucial role in the performance and lifespan of LED lighting. In recent years, the demand for driving power has been on the rise, and the industry requirements are gradually increasing, especially for outdoor and industrial lighting, which requires driving power to have excellent environmental adaptability.
Transformers are the basic equipment for power transmission and distribution, and are devices that use the principle of electromagnetic induction to change AC voltage. Transformers below 600V are called low-voltage transformers and are commonly used in electrical equipment and wireless circuits for voltage regulation, impedance matching, safety isolation, and other purposes.
Capacitors are essential basic components in electronic circuits and important components for storing electricity and energy. They play a crucial role in circuits such as tuning, bypass, coupling, and filtering. The rapid development of electronic technology has also driven the continuous growth of the capacitor industry.
Electric tools are widely used in various occasions due to their lightweight design, strong power, and convenient use. The electric tool controller is a device that controls the mechanical quantity, working sequence, and operating mode by controlling the electrical parameters of the electric tool.
Charging safety is one of the problems encountered in the rapid development of the electric vehicle industry in recent years. The scooter charger is a device specifically designed to charge batteries for scooters, and its performance plays a crucial role in the battery life and safety of scooters.
The controller is divided into a combination logic controller and a microprogram controller, each with its strengths and weaknesses. The design of a combined logic controller is cumbersome and has a complex structure. Once the design is completed, it cannot be modified or expanded, but its speed is fast. The design of a microprogram controller is convenient, with a simple structure and easy modification or expansion. To modify the function of a machine instruction, only the corresponding microprogram needs to be reprogrammed; To add a machine instruction, simply add a microprogram to the control memory, but it is done by executing a microprogram. The specific comparison is as follows: a combination logic controller, also known as a hardwired controller, is composed of logical circuits and relies entirely on hardware to achieve the function of instructions.
Pressure sensors are the most commonly used type of sensor in industrial practice. The output of a general pressure sensor is either an analog signal or a digital signal during a continuous time interval. The commonly used pressure sensors are mainly manufactured using the piezoelectric effect, and such sensors are also known as piezoelectric sensors.
A terminal is a component that connects a battery to an external conductor. In electrical engineering, terminals often refer to wiring terminals, also known as wiring terminals, which can be classified into single hole, double hole, socket, hook, etc. From the perspective of materials, copper silver plating, copper zinc plating, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.
Intelligent water meter sealing adhesive
With the rapid development of high-tech and the Internet, the concept of smart cities has emerged, A new system centered on intelligent management of "smart water" has gradually formed. Smart water meters are gradually replacing traditional water meters with their superior performance such as data sharing, information feedback, and intelligent analysis. In order to effectively protect the stable, long-term, and effective operation of smart water meters under increasingly harsh working conditions, waterproof, moisture-proof, and antifreeze adhesives play a crucial role.
