First you have to understand the function and characteristics of series-parallel circuit and hybrid circuit, and then is familiar with the principles of various electronic components and in the circuit into various forms of the role, then you can first learn to analyze the simple circuit work principle, And then you have to learn the basics of the circuit and the formula for the original in the circuit. This is important, then in practice to analyze some of the more difficult circuit, these basically good understand, you can according to their own needs, combined with a variety of components working principle, to design the circuit.Multi-Language Learning Sound Wall Chart
At the beginning of the time to start from the simple, and then in the difficult, so gradual accumulation of knowledge and experience, finally your electronic technology will reach an impressive point, this thing can not be anxious, anxious can not learn electronic knowledge, to 1.1 o ' clock.Multi-Language Learning Sound Wall Chart
No electronic circuit board maintenance This professional, electronic circuit board maintenance belongs to the electronic technology Professional category, as long as you have a certain basic theory and practice of electronic technology. Multi-Language Learning Sound Wall Chart
Can read most of the circuit diagram, then, the general circuit maintenance is not a problem.
circuit board mainly by the pad, through the hole, the installation of holes, wire, components, connectors, filling, electrical boundary circuit board and other components. Solder PLATE: A metal hole used for welding the pin of a component.Multi-Language Learning Sound Wall Chart
Over hole: A metal hole used to connect the components of each layer to the pin. Mounting holes: For fixing the circuit board. Conductor: The electrical Network copper film used to connect the pins of the components. Connectors: For the circuit board connection between the components. Filling: Deposited copper for ground network can effectively reduce impedance. Electrical boundary: Used to determine the size of the circuit board, all components on the circuit board can not exceed the boundary.Multi-Language Learning Sound Wall Chart
