In general, the domain voltage is going to be abnormal during the problematic area. Then measure the RI signal to check out in which the RI sign is interrupted. When the RI signal disappears, it may possibly essentially be determined which the chip is short-circuited or broken following becoming tinned.
Irregular temperature: Commonly, the temperature is substantial. The maximum PCB temperature established by our monitoring system can not exceed 90℃.
(2) In the event the chip however stories an integer variety just after confirming the smaller board, initially Check out if the RX signal is ordinary, in addition to measure if the chip points 1.
Measure if the area voltage is regular. Commonly, the domain voltage will probably be abnormal inside the problematic area. Then evaluate the RI sign to discover Should the RI signal is damaged. If the RI signal is missing, essentially, the chip is short-circuited or damaged following becoming tinned.
8V, one.8V patch filter capacitors (measure the resistance on the patch filter capacitors associated with the front and back of your PCBA)
In case the temperature exceeds this temperature, the miner will alarm and cannot operate Usually. Normally, you can Check out whether the drinking water outlet temperature exceeds 65 degrees, and thermal conductive gel also can cause temperature abnormalities.
Effects from mining calculator are estimation based upon The present issues, block reward, and exchange rate for unique coin. Faults can arise, so your financial commitment choice should not be based on the results of the calculator.
b. Check whether the inlet air temperature of the miner is too higher, and confirm the exhaust air is smooth.
Does any data on this site seems incorrect and you would like for us to examine it? Explain the issue with as much information and facts as you can.
7) One particular hashboard has small hashrate: As for this case, you are able to log in on the IP in the Putty software package to watch whether or not the area Doing the job voltage of this board is regular and whether the NONCE return is regular. You'll be able to repair it Based on Putty LOG prompt.
When the miner is in a very fault state, you'll want to Check out The existing log. When the miner is in a traditional point out, it is suggested to question the historic log.
3. Following repairing, the hash board need to be analyzed more than two periods to become Okay right before it might pass! 4. Check out whether or not the equipment and hash board testers can operate Ordinarily, determine the upkeep station to check software program parameters, exam fixture versions, and so forth. 5. From the test of repairing and changing the chip, the chip needs to be analyzed 1st, then the function examination shall be done just after passing. The function test must be certain that the smaller heat sink is welded competent. When installing the massive heat sink, the area on the chip have to be evenly coated with thermal gel as well as the cooling enthusiast shall be at full velocity. When utilizing the chassis to dissipate heat, two hash boards must be placed simultaneously to variety an air duct. six. When measuring the sign, use 4 admirers as guidance for warmth dissipation, as well as admirers shall manage whole speed. 7. When powering on the hash board, the person have to initial hook up the detrimental copper wire of the facility supply, then the beneficial copper wire of the facility supply, and finally plug within the signal cable. When eradicating, the order of installation have to be reversed. Initial, remove the sign cable, then remove the good copper wire of the power provide, And at last clear away the damaging copper wire of the ability provide. If your person does not abide by this buy, it is vitally straightforward to induce harm to R8, R9, U1, U2 (not all chips can be found). Just before testing the sample, the repaired hash board needs to be cooled down right before tests, or else, it may trigger PNG screening. 8. To exchange a completely new chip, printing pins and soldering paste are essential to make certain that the chip is pre-soldered then soldered to your PCBA for repair. III. hash board tester earning and matters needing notice The supporting fixture of your hash board tester really should satisfy the warmth dissipation from the hash board and aid the measurement of signals. one. Use the 19 collection hash board tester SD card swiping method for the first time to update the hash board tester control board FPGA, unzip it and duplicate it towards the SD card, and then insert the card into the hash board tester card slot; electric power on for about 1 moment and look forward to the Manage board indicator to double flash 3 situations, then the update is finished; (if it is not up to date, it could cause a certain chip for being terrible Order Now in the test). Figure three-one two. Make the examination SD card In keeping with the necessities, and directly unzip the compressed package of the single-sided warmth sink inspection chip to make the SD card; Determine 3-two three. The test SD card will be produced In accordance with the requirements, as well as the double-sided heat sink eight-periods patter take a look at ought to make an SD card, as proven during the determine under;
Test if the conductive copper bar is in weak Speak to, Look at whether or not the electrical power Manage wire is unfastened or damaged, and substitute the ability provide.
According to this process, locate the chip that also has the long-phrase operating failure right after a specific chip is brief-circuited. Typically, it is actually attributable to a specific chip harmful, so just substitute it; Determine five-twenty seven. Phenomenon: PT1 chip exam is Okay, PT2 operate exam often stories a particular chip NG;
