If your connection is OK, you can complete a PT2 examination within the board to determine if it could possibly pass the test. If it may be examined, it is essentially certain that it is a problem While using the Regulate board. If it can't be analyzed, use precisely the same repair method as PT2 to repair it.
In case the examination chip isn't thoroughly detected, the board should be repaired. Whether it is normal following the take a look at, take out the hash board independently, use the test fixture to hold it in to the Debug grasp application to mine, and regulate the fan pace to 95%.
In the event the faulty chip is located, weld the chip once again by including flux throughout the chip and heating the solder joints from the chip pins to some dissolved state. This will likely prompt the chip pins and pads to re-run in and collect the tin, reaching the result of tinning once more.
Evaluate whether or not the area voltage is regular. Typically, the domain voltage will be irregular during the problematic domain. Then evaluate the RI sign to find out In case the RI signal is broken. In the event the RI sign is missing, generally, the chip is short-circuited or ruined just after remaining tinned.
3V, plus the area voltage in the back fields are Nearly all greater than 0.38V. This example is caused by the chip not becoming soldered very well, normally 1.8V, 0.8V, RXT, CLK will not be soldered well. It is suggested to right measure the area voltage to Find which domain is the trouble. The 1V8 and RO shorter-circuit method Utilized in area a) may also Find the abnormal position;
Sample NG is a result of the big distinction between the features of your chip and various chips. At present, it really is identified which the chip die is destroyed, so just exchange the chip. In accordance with the log data, the substitute procedures are as follows:
a-three) Evaluate the resistance of R232 or R233 having a multimeter to examine whether it is inside one ohms as well as the looking through will not likely leap randomly. If not, please exchange these two resistors
eight. To exchange a fresh chip, printing pins and soldering paste are essential to make sure that the chip is pre-soldered then soldered to your PCBA for repair
At that time, Microsoft Marketing will make use of your full IP tackle and user-agent string so that it can thoroughly approach the advert click and cost the advertiser.
The fan will alarm and it'll not get the job done normally. Typically, the ambient temperature is simply too high, plus the irregular operation from the fan may also lead to abnormal temperature.
● When finding the defective chip, the chip really should be welded once again. The strategy is so as to add flux around the chip (preferably no-clean up flux), and heat the solder joints of your chip pins to some dissolved state to prompt the chip pins and pads to re-run in and gather the tin, so as to accomplish the outcome of tinning once more. When the fault stays a similar soon after re-soldering, it is possible to immediately swap the chip.
In case the voltage worth has a substantial deviation, Review it with the calculated value of the adjacent team to determine The difficulty.
When installing the big heat sink, the surface on the chip must be evenly coated with thermal gel along with the cooling lover shall be at complete speed. When using the chassis to dissipate warmth, 2 hashboards needs to be positioned simultaneously to variety an air duct.
● Once the regimen take a look at is handed (the shorter-circuit test of the final regime exam is essential to steer clear of the chip or other supplies getting burnt a result of the small circuit when the facility is turned on), the chip exam is usually done While using the hash board tester, as well as positioning is usually determined based on the examination result of the hash board tester. ● In accordance with the shown outcomes of the hash board tester detection, ranging from around faulty chip, Test the chip examination details (CO/NRST/RO/XIN/BI) and voltages for example VDD0V8 and VDD1V8. ● According to the sign circulation, aside from the RX signal, reversely transmit the sign (from No. seventy six to No. 1 chip), several of the signals which include CLK Antminer s19 Hashboard CO BO RST are forward transmission (1-seventy six), plus the irregular fault point are available in the energy offer sequence.
