Solder paste column M705, flux, board washing water with complete Alcoholic beverages; board washing water is applied to scrub up the solder residue following repair; thermal gel (specification: Fujipoly SPG-30B) is accustomed to smear the surface on the chip just after repair ；ball-planting steel mesh, solder absorption wire, solder ball (the ball diameter is suggested to become 0.
5) Just after working for a timeframe, there is no computing ability, the link into the mining pool is interrupted, then Look at the community;
There are 2 types of account passwords: one account is RXot, the password is admin; the opposite account is miner, the password is miner. This software can be employed with Debug application simultaneously.
Evaluate if the domain voltage is regular. Typically, the domain voltage are going to be irregular during the problematic area. Then measure the RI sign to see When the RI sign is broken. When the RI signal is missing, basically, the chip is short-circuited or weakened after remaining tinned.
8V and one.2V patch filter capacitors are shorter-circuited, or perhaps the IC with the LDO circuit In this particular domain has weak soldering/Fake soldering/materials damage;
d-two) The second situation; the take a look at time is sort of 2 times as long as The great board (often the worth of X will modify every time you check, and often X=0); right now, the log ordinarily has the next facts (the pink variety is not really 13 someday, determined by which seat the hashboard tester is linked to); in the test, assume which the domain voltage of all of the fields before the abnormal place is nearly below 0.
Kernel Log: it keeps documents of ANTMINER's operation stages, which serves as a means to troubleshoot some frequent challenges. The strategy to enter the miner log: enter the miner IP handle inside the tackle bar of Google or Firefox browser >> enter the user title/password (default root/root) >> the miner log
The repaired hash board is often judged as a fantastic product or service with over two passes when analyzed Together with the hash board tester.
Outcomes from mining calculator are estimation dependant on The existing Price Here problems, block reward, and exchange rate for particular coin. Faults can take place, so your expenditure determination should not be according to the results of this calculator.
5. Inside the test of repairing and changing the chip, the chip has to be tested very first, and after that the functionality check shall be carried out right after passing. The function examination ought to be certain that the little warmth sink is welded certified.
① First of all, visually inspect the hash board to view if there is any deformation or burning in the PCB. When there is any phenomenon, it must be addressed very first.
(1) When ASICNG=(0) is exhibited: 1st evaluate the entire voltage of the domain and also the 19V Enhance circuit is regular, after which you can use a short-circuit probe to short the RX take a look at issue and 1V2 examination point involving the No.
In summary, this repair approach will involve checking each chip in sequence by small-circuiting them and monitoring the serial port Procedure until finally the faulty chip is identified and replaced.
1. Seek advice from the voltage worth vary described via the signal development. In case the measurement encounters a sizable deviation with the voltage value, it may be as opposed Together with the calculated price of the adjacent team to determine.
