What are the things you don’t know about circuit boards?
The circuit board is an important internal core central system in electronic products. It contains many parts you don’t know, just like the nervous system and blood circulation system in human body. Similarly, when transmitting signals, energy is also transmitted, but there is one difference. The circuit board uses many small parts to realize this concept. Let's introduce the specific retail of circuit boards.
, Capacitor
Capacitors are set up to distribute the voltage at each place on the circuit board. They usually have about 100%. The brand is usually Samsung. They are divided into three types: solid, semi-solid and liquid. They are very small in size. Small, there are two common types: cylindrical and elliptical. There are different capacitors according to different circuit boards, such as computers, and their main distribution is as follows: electrolytic capacitors, solid capacitors, and ceramic capacitors.
, Field effect tube
It is a DC semiconductor electron tube, usually in the shape of a square, a black super-hard material, about the size of a thumb. It is usually responsible for the output of voltage, stabilizing the direction of voltage, reducing noise, etc. Function.
SMD crystal oscillator
This is also a square, but has special markings, such as different colors at the four corners, etc., which can provide high-precision oscillation.
, Chip resistor
It is also a kind of capacitor, but its appearance is different. It is a type of ceramic capacitor, which is relatively large and not located on the periphery of the circuit board.
