Normally, the domain voltage are going to be abnormal while in the problematic domain. Then measure the RI sign to determine exactly where the RI signal is interrupted. If the RI signal disappears, it could generally be determined which the chip is short-circuited or ruined right after remaining tinned.
Repair system: Check out the looks, evaluate the chip capacitor or resistance in front, ordinarily It really is attributable to poor chip soldering or possibly a chip capacitor, resistor damaging or irregular resistance;
c) LCD Screen ASIC113: (Reporting 113), it implies that the hash board can detect 114 chips at 115200 baud rate, but only 113 chips are uncovered at 12M baud rate, and 1 chip couldn't be discovered at 12M baud rate; Repair technique: Using the dichotomy strategy, limited-circuit the 1V8 exam stage as well as the RO take a look at issue involving the 38th and 39th chips Along with the quick circuit probe. In case the log can find 38 chips, there is not any trouble with the 1st 38 chips; if brief-circuiting the 47th chip, although the log stories 46th, it signifies the 47th chip can not be detected, and there is no challenge Along with the Visible inspection. Generally, the 47th chip shall get replaced; Figure 5-15 d) LCD Show ASICNG: (X, a particular chip is fixedly described), There are 2 situations: d-one) The main circumstance: the test time is essentially the same as The great board (usually the worth of X will not alter every time you examination) (test time refers back to the time from when the beginning test button is pressed to enough time when the results of ASICNG: (X) is displayed over the LCD). This example is probably going to be a result of the abnormal resistance welding with the front and rear CLK, CI, and BO of your Xth chip, so buyers shall focus on these 6 resistors. The little likelihood is due to X-one, X, X+one, that's, Amongst the 3 chips, the following pins abnormal welding circumstances in the chip arise: Figure 5-sixteen d-2) The second case: the test time is nearly two times as long as the good board (often the worth of X will alter each and every time you take a look at, and at times X=0); at this time, the log generally has the subsequent details (the red number is not really 13 someday, according to which seat the hash board tester is linked to); during the test, think that the domain voltage of all of the fields in front of the irregular place is nearly under 0.3V, plus the domain voltage of your back again fields are Nearly all increased than 0.34V. This situation is because of the chip not becoming soldered very well, generally one.8V, 0.8V, RXT, CLK usually are not soldered very well. It is recommended to specifically evaluate the domain voltage to locate which area is the problem. The 1V8 and RO short-circuit technique Employed in segment a) might also Find the irregular posture;
log-area voltage print command The particular functions are as follows: Open up putty , enter the IP of your miner in problem and click OPEN Figure six-seven two. Enter the consumer identify, password and exam command to examine the NONCE reaction status as well as position of voltage domain. If the NONCE and domain voltage are abnormal, consumer can execute measurement and routine maintenance based upon the printed abnormal chip.
eight. When changing a brand new chip, cleanse the pins and apply solder paste to make certain that the chip is coated with tin before soldering.
Pattern NG is a result of the big difference between the traits in the chip and other chips. At present, it can be observed that the chip die is destroyed, so just swap the chip. In accordance with the log data, the substitute regulations are as follows:
Please be careful not to feel any impostors, you should Examine our right Call information and facts and beware of becoming deceived receiving ripped off, and shedding revenue. please Test our ideal contact way: Below
② Detect whether the circuits of U1 and U2 are irregular, such as resistor in inadequate soldering, and many others.;
b) If a single chip can be found in step a), it implies that the initial chip along with the preceding circuit are excellent. Use a similar approach to examine the following chips. By way of example, shorter-circuit the 1V8 take a look at position as well as the RO check stage concerning the 38th and 39th chips. If your log can discover 38 chips, the initial 38 chips haven't any dilemma; if you still find 0 chips, Test the 1V8 1st; if It truly is regular, this means that there's a issue with the chip immediately after 38.
(2) U1 cannot be applied on other number of models In case the OTP function is enabled within the control board.
Carry on this method and shorter-circuit the subsequent chips one by one until a chip is found that also brings about long-phrase operating failure even after remaining small-circuited. This failure is often resulting from damage to that individual chip, and so it should be changed.
By bringing their unique equipment, participants can learn to correct up to five broken units all through Every session, creating the journey pay for itself. Don’t Allow complex Go Here facts keep you back again.
d-one) The initial circumstance: the examination time is largely the same as The great board (usually the value of X will not adjust every time you check) (check time refers to the time from when the beginning test button is pressed to time when the results of ASICNG: (X) is exhibited over the LCD).
