38. Proceed to utilize the binary technique to examine till the problematic chip is located. Assuming that there is a problem Along with the Nth chip, if the 1V2 and RX between the N-1th chip and also the Nth chip are quick-circuited, the N-one chip are available; However, when the 1V2 and RX between the N and N+1 chips are short-circuited, the entire chip can not be observed.
1. Pay attention for the system when changing the chip. There'll be no noticeable deformation in the PCB board immediately after replacing any equipment. Check no matter if you will find any open up or limited circuit difficulties during the replacement sections and encompassing components.
8V, one.8V patch filter capacitors (measure the resistance with the patch filter capacitors connected to the back and front in the PCBA)
3. The examination SD card is going to be built according to the requirements, as well as PT1 chip detection chip and PT2 functionality exam are going to be straight decompressed to generate the SD card.
; secondly, once the Visible inspection is handed, the impedance of each and every voltage area can be tested initial to detect no matter if You will find there's brief circuit or an open circuit. If found, it should be dealt with to start with. Moreover, check if the voltage of every area is about 0.36V.
Pattern NG is attributable to the massive distinction between the features from the chip along with other chips. At the moment, it is discovered that the chip die is destroyed, so just exchange the chip. Based on the log info, the substitute regulations are as follows:
Kernel Log: it retains documents of ANTMINER's Procedure stages, which serves as a means to troubleshoot some frequent challenges. The method to enter the miner log: enter the miner IP deal with from the deal with bar of Google or Firefox browser >> enter the user identify/password (default root/root) >> the miner log
The repaired hash board might be judged as a good merchandise with in excess of two passes when examined Using the hash board tester.
37V. This example is brought on by the chip not currently being soldered thoroughly, ordinarily one.2V, 0.8V, RXT, CLK will not be soldered correctly. It is suggested to right evaluate the area voltage to Track down the problematic domain. The 1V2 and RO quick circuit approach used in area a) may Identify the abnormal spot
2. The upkeep operators must have particular Digital information, more than one year of servicing expertise, and be proficient in BGA/QFN/LGA bundle soldering engineering. three. Soon after repairing, the hash board has to be analyzed for much more than two times to be Alright before it could possibly go! four. Examine whether or not the equipment and hash board testers can get the job done Typically, determine the upkeep station to test program parameters, examination fixture variations, etcetera. 5. During the examination of repairing and replacing the chip, the chip should be analyzed first, and then the functionality test shall be executed after passing. The function examination have to be sure that the little heat sink is welded Contact Here certified. When setting up the big heat sink, the surface area on the chip has to be evenly coated with thermal gel as well as cooling lover shall be at total pace. When using the chassis to dissipate heat, 2 hash boards ought to be placed concurrently to variety an air duct. The single-sided test from the production should also make sure that the air duct is formed (important). six. When measuring the sign, use 4 admirers as help for warmth dissipation, plus the followers shall sustain complete velocity. seven. When powering around the hash board, person need to to start with connect the destructive copper wire of the ability provide, then the beneficial copper wire of the power offer, And eventually plug within the signal cable. When eradicating, the purchase of set up has to be reversed. Very first get rid of the sign cable, then get rid of the favourable copper wire of the power supply, And eventually eliminate the adverse copper wire of the facility provide. When the user don't abide by this get, it is very very easy to result in damage to R233, R232 (not all chips can be found). In advance of testing the sample, the repaired hash board should be cooled down just before tests, otherwise it may cause PNG. 8. To exchange a different chip, printing pins and soldering paste are expected to make certain the chip is pre-soldered and after that soldered towards the PCBA for repair III. hash board Tester Creating and Matters Needing Consideration The supporting fixture on the hash board tester must satisfy the heat dissipation in the hash board and aid the measurement of indicators. 1. When utilizing the 19 Pro test fixture for The 1st time, you must use FPGA (compose conversion file) to update the test fixture to decompress the fpga file, duplicate each of the data files on the SD card, then insert it in the take a look at fixture card slot, electrical power on for approximately one minute, and wait for the instruction gentle flashes over 3 situations to finish the update, then remove the SD card. Observe: In the event the update is not really done, it might induce the take a look at fixture to prompt a similar chip mistake each and every time. 2: Be sure to straight decompress the conversion file and duplicate it for the SD card. (You should structure the SD card in advance of copying)
If the miner of which the Regulate board continues to be reflashed must start out Usually, the following two techniques are required:
minerstat is not just An additional calculator - It is really a robust mining System that supports your copyright journey. Raise your gains, preserve precious time, and improve efficiency with our suite of top quality features:
3V powering of your temperature sensor is standard; Check the chip linked to the temperature sensor. The fabric deformation of the massive heat sink will lead to poor heat dissipation on the chip and influence the temperature distinction.
Consult with the voltage value selection explained because of the signal pattern. When the measurement encounters a big deviation from the voltage value, it can be in contrast Using the calculated value of the adjacent team to determine.
