[0042] Working principle:

[0043] When measuring the thermal stability of the chip 1 at a certain temperature, a multi-stage time step increase method is used; the inconvenience of controlling the temperature is to adjust the fixed block 702 and the sliding block 707 to the bolt hole 706 corresponding to the temperature scale line; and the fixed block 702 is fixed by an external bolt; the duration of the device is controlled by a timer 8; the pointer 801 is rotated to the time for heating the water to the required temperature; then the external connector 12 is inserted into the water receiving box 2; the external connector 12 presses down the first pressing block 201; at this time, the first pressing block 201 presses down the limit spring 202 and contacts the connecting block 203; the electromagnet 601 is energized so that the piston 603 is adsorbed upward; the water outlet device 6 is opened, and the water in the water receiving box 4 flows into the hot water pipe 5; when the water in the hot water pipe 5 is full, at this time, the suspension ball 1102 blocks the water outlet device 6 under the action of buoyancy; the first control device 7 is energized, and the heating element 10 starts to heat the water in the hot water pipe 5 to the required temperature; at the same time, the water pump 9 is turned on , the hot water is continuously transferred to the water receiving box 2; when the required temperature is reached, the movable plug 703 pushes the sliding block 707; the first control device 7 is disconnected, and the heating element 10 stops working; when the temperature drops slightly, the mercury tube 704 senses the temperature through the heat conducting sheet 705 and contracts, and the first return spring 701 presses the sliding block 707 down to connect to the fixed block 702; the first control device 7 restarts; the cycle is repeated to keep the water temperature in the hot water pipe 5 at the required temperature; the chip 1 is inserted into the water receiving box 2; reset the timer 8; connect the input terminal 101 and the output terminal 102 of the chip 1 to the display device and the power supply; observe whether the display device is disconnected within a certain period of time; when the pointer 801 starts to enter the countdown 0, the pointer 801 presses down the second pressing block 8022 and the second reset spring 8024; at this time, the second pressing block 8022 is disconnected from the sensing block 8023; this period of evaluation time meets the standard; using this method, the time is increased step by step; the chip 1 of the same standard is evaluated.

[0044] When measuring the temperature that the chip 1 can maintain within a certain period of time, each period of time measured by the timer 8 is kept constant, the fixed block 702 and the sliding block 707 are adjusted to the bolt hole 706 with the required temperature corresponding scale, and the chip 1 of the same specification is measured by increasing the temperature in steps to observe whether the external display device is short-circuited.
