What originals are generally used for PCBA patch processing
PCBA patch processing mainly includes two major processes:PCB circuit board manufacturing and SMT patch processing, both of which will inevitably use electronic components. Electronic components are the basic part of PCBA patch processing, which also affects the function and quality of PCBA finished products. Important elements. So what are the commonly used electronic components in PCBA patch processing? The above technicians will organize and introduce for everyone.
1. Resistance
Resistors are electronic components with resistance characteristics and are one of the most commonly used components in PCBA. Resistors are divided into fixed resistors and variable resistors (potentiometers), which play the role of voltage division, current shunting and current limiting in the circuit.
2. Capacitance
Capacitor is also one of the fundamental components in PCBA processing. It is a component that stores electrical energy and plays the role of coupling, filtering, DC blocking and tuning in electronic circuits.
3. Inductance coil
Inductance coil is abbreviated as inductor, which has the function of storing magnetic energy. Inductance coils are usually composed of bobbin, winding, shield, magnetic core and so on.
4. Potentiometer
A resistor whose resistance value can be changed, that is, a resistor that can be continuously adjusted within a regular range, is called a potentiometer. The potentiometer is composed of a shell, a sliding end, a rotating shaft, a ring resistance body and 3 lead-out ends.
5. Transformer
The transformer is composed of an iron core (or magnetic 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.
The transformer is a device that transforms voltage, current and impedance. When an alternating current is passed through the primary coil, alternating magnetic flux occurs in the iron core (or magnetic core), causing a voltage (or current) to be induced in the secondary coil. Transformers are mainly used for AC voltage conversion, current conversion, power transmission, impedance conversion, buffer isolation, etc., and are one of the important components in PCBA parts.
6. Crystal diode
Crystal diodes (ie semiconductor diodes, hereinafter referred to as diodes) are made of a PN junction, electrode leads, and an externally sealed tube case. It has single-guide electrical characteristics.
7. Transistor
Transistor (hereinafter referred to as triode) is the central device for signal reduction and processing, and is commonly used in PCBA parts.
8. Field effect tube
The field effect transistor (referred to as the field effect tube) is also a semiconductor device with a PN junction. The difference from a triode is that it does not use the conductivity characteristics of the PN junction, but uses its insulation characteristics.
9. Electroacoustic devices
The devices used in the circuit to complete the mutual conversion of electrical signals and acoustic signals are called electroacoustic devices. It has a single variety, including speakers, microphones, earphones (or earplugs), microphones, receivers, etc.
10. Optoelectronic devices
Photoconductive devices that use semiconductor photosensitivity tasks, photovoltaic cells and semiconductor light-emitting devices that use semiconductor photovoltaic effect tasks are collectively referred to as optoelectronic devices.
11. Display device
Electronic display devices refer to photoelectric conversion devices that convert electrical signals into optical signals, that is, devices used to display numbers, symbols, text or images. It is a key component of the electronic display installation and has a great influence on the function of the display installation.
12. Sensor
Sensors are devices or installations that can sense regular measurements and convert them into usable signals according to certain rules, usually composed of sensitive components and conversion components.
13. Appearance device components
Surface device components (SMC and SMD) are also called chip components or chip components, which include resistors, capacitors, inductors and semiconductor devices, etc., with small size, light weight, no leads or very short leads, The device has the characteristics of high density, high reliability, good anti-vibration function, and easy automation.
14. Thyristor
SCR is the abbreviation of SCR rectifier element. It is a high-power semiconductor device with a four-layer structure with three PN junctions, also known as a thyristor. It has the characteristics of small size, absolutely complex structure, and strong function. It is one of the more commonly used semiconductor devices.
15. Switches, relays, various connectors
Switches are used in electronic equipment to cut off, connect, or switch circuits. Relay is a kind of automatic control device that when the output (electricity, magnetism, sound, light, heat) reaches a certain value, the input will change in leaps and bounds.
Regarding the commonly used electronic components for PCBA patch processing, I will see here tomorrow. These electronic components are inseparable in PCBA patch processing, and the function and quality of electronic components also affect the quality of PCBA finished products. Therefore, it is necessary to understand the function of each component in detail and choose carefully.
