Should the connection is Okay, you may execute a PT2 examination about the board to see if it may go the test. If it could be examined, it is basically certain that it's an issue Together with the Management board. If it can't be tested, use a similar repair method as PT2 to repair it.
Abnormal temperature: Frequently, the temperature is higher. The utmost PCB temperature established by our checking method cannot exceed 90℃.
3V electricity offer is normal; Examine the welding excellent of the chip which connects sensor along with the tiny warmth sink. The deformation of large warmth sink content will trigger inadequate warmth dissipation of the chip and have an impact on the temperature big difference. Determine five-13 3. Phenomenon: Solitary board detection chip isn't finish (PT1/PT2 stations)
Upkeep system: Test the looks and evaluate the capacitance or resistance of the front chip. Typically, it can be attributable to very poor chip welding or destruction and irregular resistance of a specific chip capacitor or resistor, or issues with the chip alone;
To summarize, the repair process to the hash board includes program inspection, chip exam, fault localization, and tests and verification. By these steps, the defective chip might be Situated and repaired or changed, plus the hash board may be examined to make sure it is functioning thoroughly.
● When locating the faulty chip, the chip really should be welded once more. The tactic is to add flux round the chip (if possible no-clean flux), and heat the solder joints in the chip pins into a dissolved condition to prompt the chip pins and pads to re-run in and obtain the tin, In order to achieve the impact of tinning once again. If your fault remains precisely the same just after re-soldering, you can right swap the chip. ● The repaired hash board is often judged as a superb merchandise with in excess of two passes when testing Using the hash board tester. For the first time, after changing the pieces, look ahead to the hash board to chill down, use the hash board tester to check, and once the take a look at is passed, established it aside and then neat it down. For the 2nd time, immediately after a few minutes in the event the hash board cools down, examination once more. 0 About products purchase, you should Make contact with our product sales supervisor:
3. Immediately after repairing, the hashboard must be analyzed for much more than two occasions for being OK before it can go!
The Antminer S19 Professional is a powerful miner, but its overall performance is often hindered by defective hashboards. By replacing them with our upgraded hashboards, you may make certain that your miner is usually working at its most prospective.
(2) Use the check fixture of your V2.1010 Handle board (its design is ZJ0001000001), the good and destructive poles of the power supply of your check fixture must be mounted using a discharge resistor, and it is usually recommended to make use of a cement resistor of 25 ohms and over 100W.
2. The maintenance operators should have specific electronic know-how, more than one year of maintenance expertise, and be proficient in BGA/QFN/LGA package soldering engineering. three. After repairing, the hash board should be examined for greater than two occasions to become Okay ahead of it might pass! 4. Check out whether the applications and hash board testers can perform Generally, determine the upkeep station to test application parameters, check fixture versions, and many others. five. From the test of repairing and replacing the chip, the chip should be tested 1st, and then the perform exam shall be performed right after passing. The purpose take a look at need to make sure the compact warmth sink is welded certified. When installing the large warmth sink, the surface from the chip should be evenly coated with thermal gel and also the cooling admirer shall be at entire speed. When utilizing the chassis to dissipate warmth, 2 hash boards needs to be placed concurrently to variety an air duct. The only-sided examination on the generation also needs to make sure that the air duct is formed (crucial). 6. When measuring the sign, use 4 lovers as aid for warmth dissipation, plus the supporters shall manage comprehensive pace. seven. When powering over the hash board, consumer must 1st link the negative copper wire of the ability supply, then the constructive copper wire of the power offer, And eventually plug within the sign cable. When removing, the purchase of installation must be reversed. 1st take out the sign cable, then take away the positive copper wire of the power supply, and finally take away the destructive copper wire of the facility source. In case the consumer will not observe this get, it is very easy to trigger damage to R233, R232 (not all chips can be found). Just before testing the sample, the repaired hash board should be cooled down just before testing, or else it might trigger PNG. 8. To replace a new chip, printing pins and soldering paste are needed to make certain the chip is pre-soldered and afterwards soldered on the PCBA for repair III. hash board Tester Building and Matters Needing Attention The supporting fixture with the hash board tester really should satisfy the warmth dissipation in the hash board and aid the measurement of indicators. one. When using the 19 Pro check fixture for The 1st time, you must use FPGA (create conversion file) to update the examination fixture to decompress the fpga file, duplicate every one of the data files for the SD card, then insert it in to the take a look at fixture card slot, energy on for around one minute, and anticipate the instruction light-weight flashes over three occasions to finish the update, then clear away the SD card. Observe: In case the update is not really finished, it may lead to the exam fixture to prompt exactly the same chip error anytime. Antminer s19 Hashboard two: You should instantly decompress the conversion file and copy it towards the SD card. (Make sure you format the SD card ahead of copying)
Check if the 4 resistors of R24~R27 are welding abnormally and Test whether the welding of PIN2, 3 of U3 is regular.
three. The check SD card are going to be created Based on the necessities, and the double-sided heat sink 8-moments Patter test should make an SD card, as revealed within the figure under;
Evaluate no matter if There is certainly output on the next pin of U6 and also the voltage is about three.3V; if Certainly, make sure you go on to troubleshoot the trouble; if there isn't any 3.3V, be sure to check the link standing with the hashboard tester cable as well as the hashboard is Okay, and reprogram the PIC.
Prevalent phenomena: IP cannot be detected, chain detection is abnormal. If an abnormality occurs during the examination, repairs should be performed according to the monitoring interface and exam LOG prompts. The maintenance approaches for the whole miner initial examination and aging examination are the same.
