antminer s19 pro hashboard Fundamentals Explained
Solder paste column M705, flux, board washing drinking water with complete alcohol; board washing drinking water is utilised to scrub up the solder residue soon after repair; thermal gel (specification: Fujipoly SPG-30B) is utilized to smear the surface from the chip soon after repair ；ball-planting steel mesh, solder absorption wire, solder ball (the ball diameter is recommended to be 0.
Please be careful to not consider any impostors, make sure you check our proper Get in touch with data and beware of getting deceived receiving scammed, and shedding dollars. make sure you Verify our correct Make contact with way: Below
HEX file to be programmed; the next phase: click "join" to connect Ordinarily; the 3rd move: click on the "plan" button, and after completion, simply click "verify" to prompt the verification to prove the programming is profitable.
log-domain voltage print command The particular operations are as follows: Open up putty , enter the IP of your miner in issue and click on Open up Determine six-7 2. Enter the consumer name, password and take a look at command to examine the NONCE response status plus the status of voltage area. In case the NONCE and area voltage are irregular, person can accomplish measurement and servicing dependant on the printed abnormal chip.
③ Utilize a multimeter to measure the resistor of R8 or R9 to view if it is within ten ohms, as well as the reading through won't leap randomly. Otherwise, change each resistors;
three. If the‘PIC sensor NG’is shown about the LCD display screen on the hashboard tester plus the analyzed temperature is irregular, then Adhere to the techniques under to troubleshoot:
Check the welding high-quality on the chip which connects sensor along with the tiny warmth sink. The deformation of huge heat sink substance will trigger very poor heat dissipation of your chip and have an affect on the temperature variance.
Repair strategy: Using the dichotomy system, brief-circuit the 1V8 Look Here take a look at point as well as RO examination issue between the 38th and 39th chips Along with the short circuit probe. If the log can find 38 chips, there's no challenge with the very first 38 chips; if short-circuiting the 47th chip, even so the log experiences forty sixth, it signifies that the 47th chip can't be detected, and there is no trouble Using the Visible inspection. Commonly, the 47th chip shall get replaced;
Keep on to research with dichotomy right until the problematic chip is found. Assuming that there's a trouble Together with the Nth chip, once the 1V8 and RO involving the N-1th and Nth chips are brief-circuited, N-one chips are available, but if the 1V8 and RO in between the Nth and N+1th chips are quick circuited, all the chip can't be located.

six. Following the repair, the hash board really should move a lot more than two instances to generally be judged as a good solution when analyzed with the test fixture. For The very first time, right after changing the add-ons, wait for the hash board to cool down, use the take a look at jig to check the pass, and afterwards set it apart to chill down. The second time, wait a couple of minutes for your hash plate to cool totally right before screening all over again.
