4mm); when changing a different chip, you must tin the chip pins then solder to the hashboard, after which lock big warmth sinks soon after implementing thermal gel evenly about the chip floor.
one. Concentrate into the technique when replacing the chip. There will be no apparent deformation of the PCB board soon after changing any equipment. Look at whether there are any open or short circuit challenges in the replacement sections and bordering components.
c) Liquid crystal display Exhibit ASIC113: (Reporting 113), it ensures that the hash board can detect 114 chips at 115200 baud charge, but only 113 chips are discovered at 12M baud charge, and a single chip could not be discovered at 12M baud charge; Repair approach: Utilizing the dichotomy approach, brief-circuit the 1V8 test place and also the RO exam place involving the 38th and 39th chips While using the quick circuit probe. In the event the log can discover 38 chips, there's no problem with the 1st 38 chips; if shorter-circuiting the 47th chip, even so the log stories forty sixth, it indicates which the 47th chip can not be detected, and there is no issue While using the visual inspection. Generally, the 47th chip shall get replaced; Determine five-fifteen d) LCD Screen ASICNG: (X, a particular chip is fixedly reported), there are two scenarios: d-one) The main case: the check time is largely similar to the good board (generally the worth of X won't change each time you exam) (examination time refers to the time from when the beginning examination button is pressed to time when the result of ASICNG: (X) is shown to the Liquid crystal display). This example is probably going to get attributable to the abnormal resistance welding on the entrance and rear CLK, CI, and BO on the Xth chip, so people shall concentrate on these six resistors. The compact probability is due to X-1, X, X+one, that may be, among the a few chips, the following pins irregular welding circumstances of the chip take place: Determine five-16 d-2) The second situation: the check time is nearly 2 times as long as The nice board (sometimes the value of X will transform anytime you test, and from time to time X=0); presently, the log generally has the following info (the pink selection is not thirteen someday, based upon which seat the hash board Purchase Here tester is connected to); during the exam, presume the area voltage of all the fields in front of the abnormal situation is almost a lot less than 0.3V, and the domain voltage of the back fields are Practically all bigger than 0.34V. This case is caused by the chip not getting soldered effectively, commonly one.8V, 0.8V, RXT, CLK are not soldered properly. It is usually recommended to straight measure the domain voltage to Find which area is the challenge. The 1V8 and RO quick-circuit method used in part a) might also Find the irregular place;
3. The check SD card are going to be created As outlined by the necessities, as well as PT1 chip detection chip and PT2 functionality test are going to be directly decompressed to make the SD card.
9. When replacing a brand new chip, thoroughly clean the pins and use solder paste to make certain that the chip is coated with tin ahead of soldering.
Immediately after operating for your stretch of time, there is no hashrate, plus the relationship of the mining pool is interrupted, Examine the network.
This hash board is effectively-built and appears to be constructed to previous. It delivers dependable general performance and suits my mining gear beautifully.
Repair approach: Utilizing the dichotomy method, quick-circuit the 1V8 examination point plus the RO check position concerning the 38th and 39th chips While using the quick circuit probe. If the log can discover 38 chips, there is not any problem with the initial 38 chips; if limited-circuiting the 47th chip, even so the log experiences forty sixth, it indicates that the 47th chip can not be detected, and there's no trouble Using the Visible inspection. Frequently, the 47th chip shall get replaced;
Continue to investigate with dichotomy until eventually the problematic chip is uncovered. Assuming that there's a trouble With all the Nth chip, in the event the 1V8 and RO concerning the N-1th and Nth chips are brief-circuited, N-1 chips can be found, but once the 1V8 and RO amongst the Nth and N+1th chips are shorter circuited, the whole chip can not be uncovered.
This case is likely to become brought on by the irregular resistance welding with the front and rear CLK, CI, and BO on the Xth chip, so customers shall concentrate on these six resistors. The tiny chance is due to X-one, X, X+1, that may be, Among the many 3 chips, the subsequent pins irregular welding problems from the chip occur:
Be a part of the global Local community of miners who believe in minerstat to elevate their mining game. Do you think you're wanting to unlock your mining possible?
three. When sensor NG is shown on the Liquid crystal display monitor of the fixture, the test reading temperature is abnormal. Make sure you follow the actions below to troubleshoot:
2) Considerably less url: Fewer link refers to that among the 3 boards, 1 piece is missing. Generally, There's a difficulty Together with the link among the hashboard and the Management board. Check out the cable to view if there is an open up circuit.
1. Concentrate to the operation approach when changing the chip. Right after changing any extras, the PCB board shall have no noticeable deformation. Look at the substitute areas and also the surrounding areas for open circuit and quick circuit issues.
