What are the electronic components on the pcba board

What are the electronic components on the pcba board

PCBA and pcb are not the same. PCB refers to the printed circuit board, which is the support of electronic components. It is the empty PCB board without any components on it; and PCBA refers to the empty PCB board through SMT. Then go through the entire manufacturing process of the DIP plug-in. The difference between PCB and PCBA is that the former does not have any electronic components on the circuit board, while the latter has many components placed on the circuit board. Do you know what electronic components are on the PCB? Today I will share with you those components on the PCBA board.

 1. Resistance
      One of the most commonly used components in PCBA processing is electronic components with resistance characteristics. Resistors mainly play the role of voltage dividing, current shunting and current limiting in the circuit, and can be divided into: fixed resistors and variable resistors (potentiometers).

2. Capacitance

      Like resistors, it is also the most commonly used electronic component in PCBA processing. Capacitors play the role of coupling, filtering, DC blocking and tuning in electronic circuits, and are a kind of components that can store electrical energy.

3. Inductance coil

What are the electronic components on the pcba board

Abbreviated as inductor, it is composed of skeleton, winding, shield, magnetic core, etc. The inductor coil has the function of storing magnetic energy.

4. Potentiometer

      It is a resistor that can be continuously adjusted within a specified range. It is composed of a shell, a sliding end, a shaft, a ring-shaped resistor body and 3 lead-out ends.

5. Transformer

      It is an indispensable electronic component in the PCBA machine, which is mainly used for AC voltage conversion, current conversion, power transmission, impedance conversion and buffer isolation. A transformer is a device that transforms voltage, current, and impedance. When an alternating current is passed through the primary coil, an alternating magnetic flux is generated in the iron core (or magnetic core), which induces a voltage (or current) in the secondary coil.

6. Crystal diode

      Also called semiconductor diode, or diode for short, it has unidirectional conductivity. The diode is made of a PN junction, electrode leads and an external sealed case.

7. Transistor

      Transistor for short, is a core device, mainly used for signal amplification and processing, and is widely used in PCBA complete machines.

8. Field Effect Tube

      Like a diode, it is a semiconductor device with a PN junction. The difference is that the field effect tube uses its insulating properties instead of the conductive properties of the PN junction.

9. Electroacoustic Devices

      It is a kind of components used in the circuit to complete the conversion between electrical signals and sound signals. There are many types, such as speakers, microphones, earphones (or earplugs), microphones, receivers, etc.

10. Optoelectronics
      The photovoltaic cells and semiconductor light-emitting devices that mainly use semiconductor photosensitivity to work, and use semiconductor photovoltaic effect to work are collectively referred to as optoelectronic devices.

11. Display device
      The photoelectric conversion device that converts electrical signals into optical signals is called a display device, which is a key component of an electronic display device and has a great impact on the performance of the display device. It is a device mainly used to display numbers, symbols, text or images.

12. Sensor
      Usually composed of sensitive components and conversion components, it is a device or device that can sense the prescribed measurement and convert it into a usable signal according to a certain rule.

13. Surface mount components
      Commonly known as chip components or chip components, it has the characteristics of small size, light weight, no leads or very short leads, high installation density, high reliability, good vibration resistance, and easy automation. Surface mount components include Resistors, capacitors, inductors and semiconductor devices, etc.

14. Thyristor
      The abbreviation for silicon controlled rectifier element, a high-power semiconductor device with three PN junctions and a four-layer structure. It is one of the more commonly used semiconductor devices. It has the characteristics of small size, relatively simple structure, and strong functions.

15. Switches, relays, various connectors

      Switches are used in electronic equipment to cut off, connect, or switch circuits.

      A relay is an automatic control device whose output will change leaps and bounds when the input (electricity, magnetism, sound, light, and heat) reaches a certain value.

Through the above explanation of the components on the PCBA board, I hope it will be helpful for you to understand "what electronic components are on the PCBA board"!
