Jointly complete the design of circuit board wiring and onboard equipment. Deviation Table for Technical Parameters of Printed Circuit Board Components.
Safety regulations: After failure, the interlayer must be redesigned and there must be obvious open and short circuit checks.
For the design of the printing process, designers must have detailed silk screen printing and inspection records. Even boards with silk screen printing should have the specified appearance and pattern position, otherwise it will cause errors or misunderstandings;
Inspectors are not allowed to operate or change the tapping method, and must strictly follow the mechanical performance for operation;

● Identify stress, environment, work environment, or other special areas, and receive necessary professional training and education;
● It should have a working environment related to instruments and control devices, which may sometimes affect the normal operation of sensor instruments.
● It should have process management for on-site debugging of system software to ensure the safety of instrument maintenance personnel.
Time detection should be carried out to detect the working status of the sensor. If there is time to detect the environmental conditions in which the sensor is located, attention should be paid to the overall issue.
Check the temperature for abnormal phenomena such as temperature and humidity. And it has the function of secondary recording and display of measurement and sensor data.
C. Temperature: The test temperature is 40 ° C and cannot be too high; During testing, it is not possible to keep the display constantly displayed.
Check if the sensor socket is in the correct way. When the sensor is not at the terminal, the temperature change of the thermistor causes uneven measurement points of the thermistor. Therefore, the gap between the thermistor and the terminal should be appropriately changed (i.e., there are large pits on the measured point and the heat source inside the pits is limited). If the large pit measured is cold, a grounding strap must be added to the grounding electrode winding, and the grounding point should be as close as possible to reduce measurement errors. On the contrary, the lead wires on the thermistor should be appropriately increased to reduce measurement errors.
Figure 1: During thermocouple measurement, to ensure that the thermocouple is not less than 9 Ω, wires can be used for wires that are not connected at the measurement end of the thermocouple, and wires that are not connected at the measurement end of the thermocouple can be used
