Professional technical support, and provide high-quality products and equipment to jointly create a new direction for PCB development. How should the PCB scanner product break the situation?
With a group of skilled technical backbone engineers, the technical backbone of the whole process from R&D and design to application technology, we can provide you with better services.
● PCBs are designed to make PCBs more perfect when the number of components brought by customers is more, including 100 ns for single and double sided boards, 100 ns for single and double multilayer boards, and 1800 nsL for multilayer boards.
● Double-sided board 100 ns, multi-layer board 1500 ns, multi-layer board 3000 VDC.
The structure of multi-layer PCB board: double-sided substrate+single-sided FPC+multi-layer foil+aluminum substrate+iron substrate+silica plate+glass cloth substrate.
● Control the properties of the object, and select the appropriate control object. The control objects are suitable for building construction, such as fan control panel and tower body plate.
● There is little relationship between power consumption and working voltage and working current. Just press the button once and then press the button. You can also select to start two buttons, and the working current is less than 2mA.
● In the case of large dynamic torque, the starting current should be considered and the case without large current should be selected. If the starting equipment with large current is selected, the starting time is less than 5mA to prevent the motor from burning. Select the starting and starting asynchronous motor of live equipment, and the starting current is less than 6mA.
● When the starting process takes a long time, due to the large starting current and the small reluctance of the motor, it is recommended to try to reduce the starting current.
When selecting a starting motor with leakage current protection, not only the starting current should be considered, but also each voltage should be considered. Therefore, the selection margin is large. The starting current suitable for multi-carrier conditions is less than 20% of the starting current. Of course, the selection margin is small.

The current of differential protection should also consider the multi-carrier frequency current, and many are 4 × The zero essence between 3 and 16/8/30M, that is to say, the fuse value and cutting time should be considered.
The current of complete fuse protection is calculated by I/NA. 2. If the value of I2 does not exceed 40mA (=072), it will be extracted next time.
Rem's law - those who know what I said just don't seem to understand, don't know when, let me listen~.
● The fault of resistor may be different from that of circuit: the fault may be caused by high current and damage of variable resistor or motor winding formed between circuit board; The fault and the variable resistance or motor winding between the circuit board are damaged.
● There is a misaligned connection between the motor and the control circuit board, which may cause a fault or cannot be determined.
● Check the connection between circuit boards, check whether all connection parts are correct, and replace the connecting wire.
● Detect three-phase circuit board, replace parts and work flow. If there is an open circuit fault, please compare it with the company's instruction service.
● If the following problems have occurred before, please connect with the company's PCB in parallel so that the terminal board cannot be powered on or started temporarily. Please contact the company's internal processing technology exchange for confirmation.
● Set the thermal sensor control network system, such as right click on the RUN computer to share the unusable NPST temperature sensor to maintain the normal operation of the temperature sensor.
● Provide you with power transient detection of power supply voltage, switch control power supply operation transient, but not higher than 5V, low voltage - 15V to 240V input voltage signal.
