Under the same space, S5 places 60 chips and S7 places 162 chips.

3. The temperature is too high: one of the double fans is not running, or the speed cannot reach.

4. Certainly. We are members of consensys blockchain. The members of consensys blockchain mainly cooperate in expanding social impact.

7. ① To solve this problem, if there is 320 V voltage after rectification and filtering, then measure whether the voltage to ground of each pin of the switching power supply stabilized voltage thick mode chip is normal. If there is any abnormality, check the components around the abnormal pin of the chip, such as optocoupler, piezoresistor of sampling circuit As well as the secondary output rectifier filter elements of switching transformer
2. If the components around the above chips are normal, it can be judged that the thick die
chip is damaged.
