PatternNG is a problem that occurs resulting from substantial differences inside the properties of a particular chip when compared to other chips. To take care of this problem, it has been determined the chip’s die is destroyed and desires to be replaced.
(three) Swap the a single with the next reply and also the a single having a lessen reply. Following the swap, take a look at the hash board all over again to check whether the reply with the ASIC chip is standard. If it is irregular, measure whether or not the voltage in this domain is reduced than the normal benefit.
The voltage of each voltage area is about 0.32V. When there is 16V energy provide, usually it's got domain voltage. The priority is specified to evaluate the output of the facility supply terminal of the hashboard and Check out if the MOS is short-circuited (measure the resistance amongst pins one, 4 and 8). If 16V has electric power offer but no domain voltage, proceed to examine.
eight. To exchange a different chip, printing pins and soldering paste are demanded making sure that the chip is pre-soldered and then soldered to the PCBA for repair
Ordinary indicates You will find there's difficulty with chips immediately after 38 chips. Keep on utilizing the dichotomy strategy until finally you find the problematic chip. Assuming that there is a difficulty Together with the N-th chip, then when 1V2 and RO in between the N-1 and N chips are short-circuited, the N-one chip can be found. But when 1V2 and RO in between the N and N+one chips are short-circuited, the entire chip cannot be discovered.
● When locating the faulty chip, the chip needs to be welded once again. The strategy is so as to add flux across the chip (if possible no-clean flux), and warmth the solder joints from the chip pins to some dissolved point out to prompt the chip pins and pads to re-operate in and obtain the tin, In order to attain the result of tinning yet again. When the fault remains precisely the same right after re-soldering, you are able to immediately substitute the chip. ● The repaired hash board could be judged as an excellent solution with in excess of two passes when screening Using the hash board tester. For The Antminer s19 Pro Hashboard 1st time, just after changing the sections, look forward to the hash board to cool down, use the hash board tester to check, and following the check is passed, established it aside and after that cool it down. For the 2nd time, right after a few minutes in the event the hash board cools down, examination once again. 0 About goods order, be sure to Speak to our revenue manager:
Kernel Log: it retains documents of ANTMINER's operation levels, which serves as a way to troubleshoot some widespread difficulties. The method to enter the miner log: enter the miner IP address inside the handle bar of Google or Firefox browser >> enter the person title/password (default root/root) >> the miner log
Verify the welding excellent of the heat-sensitive chip as well as the small heat sink. The deformation of the big heat sink substance will trigger lousy heat dissipation with the chip and affect the temperature variation.
c-one) Scenario one: The test time is essentially the same as that of an Alright board (normally the worth of X does not modify every time it is actually examined). (The exam time refers to the time from pressing the beginning check button on the Liquid crystal display displaying The end result ASIC NG: X).
Repair process one: Measure if the domain voltage with the reset low chip domain is decrease than the traditional area, whether it is reduced, measure if the pin resistance with the reset small chip is larger than that of the conventional chip.
Log classification: present log, only records the current log when the miner is begun; historical log, records the logs the miner has created, however the record written content is limited, which include if it exceeds the upper Restrict, only the most recent is saved.
If your voltage benefit has a significant deviation, compare it With all the measured price of the adjacent team to determine the issue.
Should the serial port stops long-length operating after the quick-circuit, it means the 1st chip is Alright. In keeping with this technique, locate the chip that also fails after a long-length functioning following a chip small circuit. Frequently, it is actually caused by a broken chip, and you can change it;
