The purpose of making the temperature measuring board:

Quickly produce a temperature measuring board that is correct and meets the needs of the process, to prevent the failure of the temperature measuring board from not simulating the true profile temperature, improve the success rate of the temperature simulation test, ensure the effective use of the temperature measuring board and ensure product quality.

 

 

Matters needing attention:

1 The temperature measuring board is maintained and kept by the temperature measuring staff; it is necessary to check that the temperature measuring board does not stick to foreign matter and is not contaminated before the temperature measurement.

2 If the material on the temperature measuring plate is lost during the furnace temperature test, it must be found and refilled immediately to ensure the integrity of the temperature measuring plate.

3 Every time the temperature measuring board is used, record it once. The number of production changes cannot be used to replace the number of uses of the temperature measuring board.

4 When the temperature is too high or too low, and the time in the temperature range does not meet the standard, the board must be stopped immediately. The production line shall conduct a comprehensive inspection of the PCB that has been heated within one hour. The process group of the engineering department resets the furnace temperature and retests OK You can continue to cross the board afterwards.
