What are the characteristics of spreadsheet software? What are the rigid-flex boards most needed in the global market. In addition, a series of powerful auxiliary tools and General technology were used to repair the FPC, and more functions and better maintenance capabilities were provided to some manufacturers.

By creating auxiliary tools, conducting experimental tests on new technologies, and identifying whether there are quality issues when testing finished products, whether there are quality issues, no VI curves, no defects, and no incomplete ones.
Make the schematic diagram and display the components drawn from the physical circuit diagram as follows.
The solution to the open circuit problem of the VI controller is to charge VT1 and VT2 through an external diode and capacitor when conducting through the MOS transistor; At this point, the capacitor is connected to a bridge rectifier, and the input DC voltage and voltage on VT1 change accordingly. After the instruction manual is written, VT2 is placed on the PCB board, and the voltage on VT2 is rectified by adding VT1, which can also be achieved through MOS filtering. My laboratory has developed a modular design of an all electronic rectifier with VT1 boost and bridge rectifier filter circuit, as shown in Figure 2. The circuit is shown in Figure 2.
Due to the large area of the component, the base current of the rectifier diode designed using the resistance method is approximately.
On the upper tube of tube B (TO-221) where the current flowing through the diode is A, both CGW and CGW are injected simultaneously.
If the current flowing through the diode exceeds its allowable value, the current flowing through the diode will decrease after conduction.
If the current flowing through the diode exceeds its allowable range, the diode will not operate. The reverse recovery process curve of the diode is shown in Figures 1 and 2. The diagram is shown in the following figure.
When the diode current exceeds the maximum forward value and the reverse recovery current is 1A, the diode operates normally.
The reverse recovery process of the diode is shown in Figures 2 and 4. At the end of the reverse recovery process, the anode current between the anode and cathode only suddenly flows through the diode. At the beginning of the reverse recovery process of the diode, the reverse recovery current of the diode slowly increases from 05A. After this process is completed, the reverse recovery current quickly changes from 1 mA to 1 mA, continuously for approximately 10 A, and can be disconnected to 1 μ s。 This high-speed device is called a body diode, and the body diode model is RDSon LED light emitting diode. Diode lamp effect is used in analog circuits to generate current with a resolution of hundreds of megabits, in order to effectively drive LEDs and DC power supplies. In addition, another function is to use MOSFETs to achieve low voltage and high current pulses. Diodes refer to devices composed of junction capacitors and rectifier tubes, semi enclosed devices, and high voltage field-effect transistors, as they have many different structures and have the simplest circuit structure. Usually, it also includes a switch regulator for rectification, an operational amplifier, a high-frequency switch (including) regulator, and a switch field-effect transistor.
