IP cannot be detected, the amount of admirers is abnormal, and also the chain is abnormal. If there is an abnormality from the examination, Stick to the checking interface and check LOG prompts for servicing.
If there is Fake welding, it should be re-soldered. When there is destruction, it needs to be calculated if the resistance benefit is normal. Exchange the corresponding factors abnormally, and Check out the little board soldered within the PCB; the smaller board is proven during the figure down below.
8V, one.8V patch filter capacitors (evaluate the resistance from the patch filter capacitors associated with the front and back from the PCBA)
Energy on for approximately 1 moment and anticipate the indicator mild around the control board to double flash 3 times prior to the update is finished (if It is far from current, a certain chip may very well be documented as defective during the check).
The voltage of each voltage domain is about 1.35V. If there is a 14V powering, there is normally a site voltage, along with the output of the facility terminal of your hash board is measured 1st; if there is a 14V powering but no domain voltage, keep on to examine down.
Pattern NG is a result of the massive difference between the qualities in the chip as well as other chips. At present, it really is observed which the chip die is harmed, so just change the chip. According to the log info, the substitution policies are as follows:
a) If the Liquid crystal display Show ASIC NG: (0), to start with measure the whole domain voltage of 21V as well as Increase circuit voltage of 25V once they are normal. Then use a short-circuit probe to quick-circuit the RO test level and 1V2 examination issue in between the 1st and next chips, and after that run the chip discovering software.
The Antminer S19 is a robust miner, but its efficiency can be hindered by faulty hashboards. By changing them with our upgraded hashboards, you'll be able to make sure your miner is often running at its greatest potential.
Servicing personnel needs to have Digital knowledge, a minimum of one 12 months of servicing knowledge, and proficiency in BGA/QFN/LGA packaging and welding know-how.
2. The upkeep operators will need to have specific Digital know-how, multiple year of routine maintenance practical experience, and be proficient in BGA/QFN/LGA package deal soldering technologies. three. Following repairing, the hash board must be examined for greater than two periods to generally be OK right before it may pass! 4. Test whether the equipment and hash board testers can perform normally, determine the maintenance station to test software package parameters, test fixture versions, etcetera. 5. During the check of repairing and replacing the chip, the chip has to be examined initially, and then the purpose exam shall be executed following passing. The functionality examination ought to make sure the small heat sink is welded competent. When installing the massive heat sink, the surface of the chip must be evenly coated with thermal gel along with the cooling admirer shall be at total speed. When utilizing the chassis to dissipate heat, two hash boards really should be positioned concurrently to sort an air duct. The single-sided test in the manufacturing also needs to be sure that the air duct is fashioned (critical). 6. When measuring the signal, use four lovers as support for warmth dissipation, as well as the supporters shall preserve comprehensive speed. seven. When powering about the hash board, person have to first join the damaging copper wire of the ability source, then the beneficial copper wire of the power offer, And eventually plug in the sign cable. When getting rid of, the buy of installation have to be reversed. Initial clear away the sign cable, then clear away the constructive copper wire of the ability offer, And eventually take away the negative copper wire of the facility offer. In the event the consumer tend not to stick to this purchase, it is rather very easy to cause damage to R233, R232 (not all chips are available). Right before tests the sample, the repaired hash board needs to be cooled down before tests, or else it may cause PNG. eight. To interchange a completely new chip, printing pins and soldering paste are required to ensure that the chip is pre-soldered and after that soldered to your PCBA for repair III. hash board Tester Building and Matters Needing Notice The supporting fixture from the hash board tester should satisfy the warmth dissipation in the hash board and facilitate the measurement of alerts. one. When using the 19 Professional examination fixture for the first time, you might want to use FPGA (generate conversion file) to update the examination fixture to decompress the fpga file, duplicate each of the information on the SD card, then insert it into the exam fixture card slot, electric power on for about one moment, and anticipate the instruction light-weight flashes much more than 3 moments to accomplish the update, then take out the SD card. Buy Now Notice: Should the update isn't completed, it might lead to the exam fixture to prompt exactly the same chip error whenever. 2: Be sure to directly decompress the conversion file and copy it towards the SD card. (You should structure the SD card in advance of copying)
six. Following the repair, the hash board should move over two occasions to become judged as a fantastic product or service when examined from the test fixture. For the first time, just after replacing the accessories, look ahead to the hash board to chill down, use the take a look at jig to test the move, after which you can set it apart to chill down. The second time, wait a few minutes for the hash plate to cool wholly right before screening yet again.
This spare component is precisely created for straightforward routine maintenance and repair on the S19 Professional hash board, making certain seamless functions and large-performance mining.
In summary, this repair system consists of checking Each individual chip in sequence by small-circuiting them and monitoring the serial port operation until finally the defective chip is recognized and changed.
Check with the voltage price selection described from the sign craze. In case the measurement encounters a substantial deviation in the voltage value, it could be in comparison Using the calculated worth of the adjacent team to determine.
