3. In case the PIC sensor NG is exhibited over the Liquid crystal display screen of the hash board tester along with the examination read through temperature is irregular, then Stick to the ways below to troubleshoot: A) Check out whether the 4 resistors of R24~R27 are welding abnormally, and check whether or not the welding of PIN2, three of U3 is normal; Figure five-13 B) Check out if the 4 temperature senses U4, R28~R30, U6, R31~R33, U7, R34~R36, U8, R37~R39 and the matching resistance welding are abnormal, The situation from the temperature feeling is shown in Figure 5-14, the temperature sense is all Found about the back again of the PCB, the resistance is found about the entrance with the PCB, and whether or not the temperature-delicate 3.3V power source is ordinary;
● After the routine take a look at is handed (the brief-circuit exam of the general schedule take a look at is critical to avoid the chip or other products getting burnt due to brief circuit when the ability is turned on), the chip take a look at might be executed Using the hashboard tester, and also the positioning is often determined in accordance with the check results of the hashboard tester.
