1, self-study, the first thing we do is to choose reliable circuit board maintenance books or circuit board maintenance teaching videos.

2, to learn to know the components in the circuit board, mainly to understand their characteristics and functions in the circuit board, such as patch capacitors, resistors, diodes, triodes, IGBT, etc.

3. Learn to use various circuit board maintenance tools, such as multimeter, digital bridge, oscilloscope, capacitance meter, welding torch and so on.

4. We need to master the circuit board maintenance technology, and also have the analysis ability of some classic circuits, which is helpful to make an accurate judgment on the circuit board fault as a whole.

We should learn to repair and replace all the components of the circuit board on the spot.

6. It is necessary to carry out the practical work of circuit board maintenance. It is suggested that novices can take part in training or find a maintenance company that recruits apprentices to accumulate experience.

The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high-frequency board, thick copper plate, impedance board, PCB, ultra-thin circuit board, printed (copper etching technology) circuit board, etc.

The circuit board makes the circuit miniaturized and intuitive, which plays an important role in mass production of fixed circuits and optimization of electrical layout. The circuit board may be called a printed circuit board or a printed circuit board,

English name is PCB, FPC board (FPC board is also called flexible printed circuit board) Flexible printed circuit board is a highly reliable and excellent flexible printed circuit board based on polyimide or polyester film.
