2. I want to learn circuit, mainly designing and making circuit boards.
3. Circuit foundation, signal and system, digital electricity, analog electricity, etc. You must study in the basic course. Then there is the hands-on experiment. Finally, simply learn Protell.
4. Interest is the best teacher. If you are not interested in circuits and want to learn well, the best way is to cultivate interest first.
Question 2: How can we understand the working principle of the circuit board? First of all, you should restore the circuit to the state of electrical schematic diagram, so that you can understand the principle of the circuit, that is, the working principle.
Question 3: What do you think of the circuit board? study
Question 4: How to treat the circuit board? What kinds of circuit boards are commonly used? The hand boards for your own use are generally experimental boards, one-layer boards and two-layer boards. It is not important to look at the performance of the circuit board, but mainly the layout problem. As long as you can understand the circuit diagram and lay out according to the layout principle, the boards laid out by different people will be different!
Question 5: How to understand the skills of circuit boards? First of all, you should restore the circuit to the state of electrical schematic diagram, so that you can understand the principle of the circuit, that is, the working principle.
Question 6: What do you think of the circuit board? First of all, we should sum up more:
General rule: resistance is represented by r; The capacitance is represented by c; Diodes are represented by d; The triode is represented by q; The chip is represented by IC, and the crystal oscillator is represented by CST (although some people don't express it this way because of different usage habits).
It is suggested that the best way is: it is best to get a less complicated circuit board and look at the schematic diagram one by one. When you are familiar with the circuit board (intentional device), the circuit will naturally be familiar with it.
If you are familiar with the characteristics and functions of each component in the circuit, you will naturally understand.
But this is a process, take your time!
Good luck!
Question 7: How to read the circuit diagram easily? You can buy some introductory books for 5 points. From the simple beginning, large circuits are generally composed of many small circuits.
The identification of circuits includes the judgment of correct circuits and wrong circuits, and the judgment of series circuits and parallel circuits. Error circuits include the lack of necessary components (including power supply, electrical appliances, switches, wires) in the circuit, failure to form a current path, open circuit or short circuit.
Current direction method is usually used to judge the connection of circuits.
If the current flows through each appliance in turn without shunt, the appliances are connected in series;
If the current branches back and forth when passing through the appliances, that is, the current passing through each appliance is a part of the total current, then these appliances are connected in parallel.
When judging the connection of a circuit, a wire is usually used to connect two points of the circuit. In junior high school, the resistance of wires can be ignored, so two points connected by a wire can be regarded as one point, so sometimes it is very convenient to judge the connection of circuits by the method of "node".
The circuit connection method is as follows:
1. Draw the circuit diagram before connecting the circuit.
2. Put the circuit elements in the corresponding positions in the circuit diagram.
3. The circuits should be connected in a certain order.
4. When parallel circuits are connected, they can be connected in the order of "branch first", that is, the trunk line is connected first, then the branch line is connected in parallel to the same two ends of the circuit, or connected in the order of "branch first, then branch".
Pay attention to the following points when connecting the circuit:
1. During the circuit connection, the switch should be turned off.
2. Each connection must be firmly connected to prevent virtual connection.
3. Connect the electrical appliances, switches and other components first, and then connect the power supply.
4. Check carefully after connection and turn off the switch after confirmation.
5. After closing the switch, if there is any abnormality, immediately disconnect the circuit, carefully check and troubleshoot.
Question 8: What do you think of the circuit board? First, you will be able to read the circuit diagram. Then the circuit board only has different parts in the circuit diagram. Of course, as to why it should be placed like this, that is another question. So, when you say that you can read the circuit board, you have to learn from the circuit diagram first.
Question 9: How to quickly understand the circuit schematic diagram 1? After learning the circuit, you can combine the soft text with the topic sea, make the circuit and edit the corresponding application software.
2, learned the circuit is mainly to design and manufacture circuit boards.
3. Circuit foundation, signal and system, digital electricity, analog electricity, etc. You must study in the basic course. Then there is the hands-on experiment. Finally, simply learn Protell.
4. Interest is the best teacher. If you are not interested in circuits and want to learn well, the best way is to cultivate interest first.
