I think a good Placement actually completes more than half of a PCB design. rigid-flex boards are mostly successful in doing these things well.
（1） This sample does not meet market requirements. Good graphic design is the ability to present a complete circuit board with certain logical functions.
The figure shows a typical structure like this. It is necessary to observe two circuits from a system perspective. On computers, most other ordinary circuits have this structure. These circuits are composed of insulated devices and resistor caps installed on the circuit board. The problem with the circuit on the circuit board is the function of the circuit, but this does not mean that the circuit is difficult to function properly, and the circuit system still requires a large amount of power supply.
The diagram is a typical design structure where the circuit separates the power supply and signal converter, which requires an integrated power supply.
The required power supply is mainly to connect the power supply in series, and then select the power factor of current demand based on its power factor, and add voltage evaluation.
Using a set of determined power factors (required operating voltage) and two target power factors, namely the purpose: power factor. It determines the current of the load and determines it in the form of voltage, and then connects the power supply in parallel.
Step is a fixed value resistor, which is composed of line voltage, current, and resistance for the load voltage. The voltage source is easy to design and all functions are within the circuit. If the voltage calculated by the circuit is this value, the voltage will indicate that it is fixed or may be uncertain.
When we want to design a resistor and the current is provided by it, we need to consider the selection when determining its value. The resistance is constant, but for our circuit, it does not change, but in this way, the change in resistance value will not have any negative impact on the resistance.

Yes, it is possible. It only has a gate circuit in front of the power circuit. For a well used capacitor, its open source current is equal to the J of the power transistor, and the working principle of J is exactly opposite to the characteristics of the resistor.
The impedance voltage level of a capacitor is different, and the greater the DC current, the greater the insulation resistance of the capacitor.
The two poles of a capacitor are attracted to each other. There may be impedance between the two poles of a capacitor, which can cause direct current resistance of the inductance.
When the voltage at both ends cannot suddenly change, the performance of the capacitor is greatly reduced, and the capacity of the capacitor is also large. When the current increases, its performance will be greatly reduced.
When the stroke of the right end of the switch handle is greater than the external force pushing it out to the left, its mechanical characteristics cannot be restored and it is removed. The handle is announced to exit, and the capacitor bank is burned out.
