4mm); when changing a new chip, you should tin the chip pins then solder towards the hashboard, and afterwards lock large heat sinks just after implementing thermal gel evenly to the chip floor.
It is frequently because of significant ambient temperature and irregular enthusiast operation for the machine to not manage to do the job Generally. Irregular admirers operation will even trigger abnormal temperature.
Ahead of testing the pattern, the repaired hashboard should awesome down before tests; normally, it can bring on tests NG.
Get the top mining performance out within your Antminer S19 Pro by utilizing the ideal software. Join minerstat and find the most fitted software package for the setup.
For that LCD Display screen ASIC75, shorter-circuit the 1V8 exam level as well as the RO test place amongst the 38th and 39th chips. If limited-circuiting forty seven chips, however the log reviews 46, it implies the 47th chip can't be detected, and also the 47th chip really should get replaced.
Or the two ASIC chips in this area usually are not soldered adequately. The majority of them are attributable to shorter circuit of 0.8V and 1.2V patch filter capacitors (evaluate the resistance of your patch filter capacitors connected with the back and front sides on the PCBA).
The next fault illustrations are from Antminer 19 series mining machines, other Antminer versions are for reference only.
Repair process: Using the dichotomy system, small-circuit the 1V8 examination stage and also the RO exam place among the 38th and 39th chips With all the brief circuit probe. Should the log can find 38 chips, there is no challenge with the main 38 chips; if quick-circuiting the 47th chip, however the log studies 46th, it implies which the 47th chip can not be detected, and there's no trouble Together with the Visible inspection. Commonly, the 47th chip shall get replaced;
Action 7: The temperature sensor is located on the facet of chips, as well as resistor is located to the front of the PCB. Verify the soldering with the temperature sensor IC, whether the close by resistors are ruined, and if the 3.
seven) 1 hashboard has very low hashrate: As for this example, you'll be able to log in for the IP from the Putty software to observe whether or not the area working voltage of the board is normal and whether or not the NONCE return is ordinary. You could repair it Based on Putty LOG prompt.
d-1) The main circumstance: the take a look at time is essentially similar to The great board (typically the worth of X will not likely modify every time you check) (check time refers to the time from when the start take a look at button is pressed to the result of ASICNG: (X) shown about the LCD).
three. After repairing, the hash board has to be examined much more than two occasions to become Okay in advance of it can pass! 4. Look at whether the resources and hash board testers can operate Commonly, determine the upkeep station to check software package parameters, exam fixture variations, and many others. five. During the exam of repairing and changing the chip, the chip ought to be examined 1st, after which you can the functionality exam shall be done soon after passing. The operate examination need to make certain that the tiny warmth sink is welded skilled. When putting in the large warmth sink, the surface of your chip need to be evenly coated with thermal gel plus the cooling admirer shall be at full pace. When utilizing the chassis to dissipate heat, two hash boards really should be placed simultaneously to form an air duct. 6. When measuring the sign, use 4 lovers as help for warmth Buy Here dissipation, and also the lovers shall retain total speed. 7. When powering over the hash board, the user should to start with connect the adverse copper wire of the facility source, then the constructive copper wire of the facility source, and finally plug while in the sign cable. When eliminating, the buy of set up needs to be reversed. Initial, get rid of the sign cable, then eliminate the optimistic copper wire of the ability provide, and finally take away the detrimental copper wire of the ability offer. In case the consumer does not observe this buy, it is rather simple to result in damage to R8, R9, U1, U2 (not all chips are available). Before tests the pattern, the repaired hash board should be cooled down prior to testing, or else, it may well bring about PNG testing. eight. To switch a whole new chip, printing pins and soldering paste are necessary to make sure that the chip is pre-soldered and then soldered into the PCBA for repair. III. hash board tester generating and matters needing notice The supporting fixture of the hash board tester should really satisfy the warmth dissipation of your hash board and facilitate the measurement of indicators. one. Use the 19 sequence hash board tester SD card swiping program for The very first time to update the hash board tester control board FPGA, unzip it and duplicate it into the SD card, then insert the cardboard in to the hash board tester card slot; electric power on for approximately 1 minute and look forward to the Manage board indicator to double flash 3 moments, then the update is done; (if It isn't up to date, it could cause a certain chip for being undesirable in the test). Figure three-one 2. Make the examination SD card In keeping with the necessities, and specifically unzip the compressed offer of The one-sided heat sink inspection chip to generate the SD card; Figure 3-two 3. The examination SD card will be designed In keeping with the necessities, plus the double-sided heat sink 8-moments patter examination has to make an SD card, as shown in the determine underneath;
② The 2nd situation: Micro-shorter circuit amongst alerts (0-a huge selection of ohms), a result of the little resistor price of the chip pins, initial make use of a heat gun to solder and find out whether it is Okay;
a. Check if the heat sink with the hash board is adhered to by foreign objects such as dust, catkins, insects, and many others. The dust accumulation about the hash board will result in poor heat dissipation, and it needs to be cleaned and cooled in advance of turning within the miner.
