PCBA Tech - Various characteristics of components in SMT processing plants

Components are essential in SMT small-batch chip processing plants. Whether it is SMT chip processing or DIP plug-in, the purpose is to assemble the components on the PCB circuit board. Electronic components are the basic materials of the electronic processing industry, and the quality of components will also directly affect the quality of the final product. Electronic components include: resistors, capacitors, inductors, potentiometers, electron tubes, radiators, electromechanical components, connectors, semiconductor discrete devices, electro-acoustic devices, laser devices, electronic display devices, optoelectronic devices, sensors, power supplies, switches, micro Special motors, electronic transformers, relays, printed circuit boards, integrated circuits, various circuits, piezoelectrics, crystals, quartz, ceramic magnetic materials, substrates for printed circuits, special materials for electronic functional technology, electronic adhesive (band) products, Electronic chemical materials and parts, etc.

Electronic components are components of electronic components and small machines and instruments. They are often composed of several parts and can be used in similar products. They often refer to certain parts in electrical appliances, radios, meters and other industries, such as capacitors, transistors, General term for electronic devices such as hairsprings and clockwork. Common ones are diodes and so on. SMT small-batch chip processing factory to share the characteristics of various commonly used components.

1. Triode Triode is the central device for signal reduction and processing, and is commonly used in various electronic parts.

2. Optoelectronic devices Optoelectronic devices refer to devices made according to the photoelectric effect called optoelectronic devices, also called photosensitive devices.

3. Diode The diode is made of a PN junction, electrode lead and an external sealed tube case, it has a single guide electrical characteristics

4. Capacitor Capacitor is a component for storing electric energy, which plays the role of coupling, filtering, DC blocking and tuning in electronic circuits.

5. Inductance Inductance coil is abbreviated as inductance, which has the function of storing magnetic energy. Inductance coils are usually composed of bobbin, winding, shield, magnetic core and so on.

6. Electroacoustic devices Electroacoustic devices are used to complete the mutual conversion of electrical signals and acoustic signals in electronic processing, such as speakers, microphones, earphones, and microphones.

Seven, display devices Electronic display devices refer to photoelectric conversion devices that convert electrical signals into light signals, that is, devices used to display numbers, symbols, text or images.

8. Transformer A transformer is composed of an iron core and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary winding, and the other windings are called the secondary winding.

Nine, Field Effect Transistor Field effect transistor is also a kind of semiconductor device with PN junction. Unlike the triode, it does not use the conductivity characteristics of the PN junction, but uses its insulation characteristics.

10. Resistance Resistance is an electronic component with resistance characteristics, and is one of the components of the SMT chip proofing factory. Resistors are divided into fixed resistors and variable resistors, which play the role of voltage division, current shunting and current limiting in the circuit.

11. The resistor whose resistance value of the potentiometer can be changed, that is, the resistor that can be continuously adjusted within the regular range, is called the potentiometer. The potentiometer is composed of a shell, a sliding end, a rotating shaft, a ring resistance body and 3 lead-out ends.

12. Sensor A sensor is a component of a detection device that can sense the information being measured, and can transform the sensed information into electrical signals or other required forms of information output according to a certain rule to meet the transmission of information, Processing, storage, display, recording and control requirements.

13. Appearance device components Appearance device components (SMC and SMD) are also called chip components or chip components. SMC and SMD commonly used in SMT chip proofing processing plants include resistors, capacitors, inductors and Semiconductor devices, etc., have the characteristics of small size, light weight, no leads or very short leads, high device density, high reliability, good vibration resistance, and easy automation.

14. Switches, relays, and various connector switches are commonly used in the function of cutting off, connecting, or converting electronic devices in SMT small batch chip processing plants. A relay is an electrical control device. It is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the input quantity (excitation quantity) changes to the specified requirements. Connectors are also called connectors, also called connectors and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signal.
