In the event the link is OK, you are able to execute a PT2 check about the board to discover if it may possibly go the exam. If it might be analyzed, it is basically certain that it is a problem Together with the Management board. If it cannot be examined, use exactly the same repair system as PT2 to repair it.
When there is false welding, it ought to be re-soldered. If there is destruction, it ought to be calculated whether the resistance price is typical. Replace the corresponding factors abnormally, and Check out the compact board soldered within the PCB; the compact board is revealed inside the figure under.
Ahead of screening the sample, the repaired hashboard must amazing down right before testing; normally, it is going to lead to testing NG.
8. To switch a different chip, printing pins and soldering paste are demanded to make certain the chip is pre-soldered and then soldered into the PCBA for repair
Sign up for the global community of miners who have confidence in minerstat to elevate their mining match. Will you be all set to unlock your mining opportunity?
B) Verify whether the 4 temperature sensors of U5，R216、R219、R220，U7，R221~R223，U8，R224~R226，U9，R229~R231 plus the matching resistance welding are abnormal, The situation on the temperature feeling is as revealed in Figure four-4 and five-13, the temperature sensor is all Positioned within the back again of the PCB, the resistance is situated on the back and front in the PCB, and whether the temperature sensor three.3V ability offer is usual;
three. If your PICsensorNG is exhibited on the LCD display in the hashboard tester and also the take a look at examine temperature is abnormal, then Keep to the steps beneath to troubleshoot:
② Detect whether the circuits of U1 and U2 are irregular, for example resistor in poor soldering, and so on.;
Microsoft and DuckDuckGo have partnered to provide a research Answer that provides appropriate adverts to you personally while guarding your privacy. Should you click a Microsoft-delivered advert, you can be redirected for the advertiser’s landing webpage via Microsoft Promoting’s platform.
This example is likely to be because Get It Here of the irregular resistance welding in the entrance and rear CLK, CI, and BO from the Xth chip, so users shall deal with these six resistors. The tiny chance is due to X-1, X, X+1, which is, One of the a few chips, the subsequent pins abnormal welding ailments with the chip happen:
six. Following the repair, the hash board should move in excess of two times to be judged as a good item when examined by the check fixture. For the first time, after changing the extras, wait for the hash board to chill down, use the check jig to test the go, and afterwards set it aside to cool down. The 2nd time, wait around a couple of minutes for the hash plate to chill absolutely before tests all over again.
minerstat is not just Yet another calculator - It is really a strong mining System that supports your copyright journey. Enhance your gains, save worthwhile time, and increase effectiveness with our suite of high quality features:
a-three) Evaluate the resistance of R8 or R9 using a multimeter to check whether it is within 10 ohms along with the reading will never leap randomly. If not, you should replace both of these resistors. a-four) Test if the pins of the primary chip are usually not soldered nicely (it was found in repair the pins are tinned observing in the aspect, although the pins are not stained with tin whatsoever when the chip is taken off). b) If a person chip are available in phase a), it signifies that the very first chip as well as former circuit are superior. Use the same strategy to examine the next chips. Such as, shorter-circuit the 1V8 take a look at place as well as the RO examination position involving the 38th and 39th chips. If the log can discover 38 chips, the primary 38 chips don't have any issue; if you continue to uncover 0 chips, Verify the 1V8 to start with; if It can be ordinary, it means that there is a problem with the chip soon after 38. Continue to investigate with dichotomy right up until the problematic chip is identified. Assuming that there's a problem Using the Nth chip, when the 1V8 and RO involving the N-1th and Nth chips are brief-circuited, N-1 chips can be found, but if the 1V8 and RO involving the Nth and N+1th chips are short circuited, the complete chip can't be uncovered.
a) Liquid crystal display display ASICNG: if (0), very first measure the entire voltage in the measuring area plus the boost circuit 19V is typical, and afterwards use the limited-circuit probe to limited-circuit the RO take a look at place as well as 1V8 exam place between the first and the 2nd chip, after which you can run the program to find the chip.
