b) If just one chip are available in phase a), it signifies that the 1st chip and also the former circuit are ordinary. Use an analogous technique to examine the next chips. For instance, When the 1V2 exam point and RO check level involving the 38th and 39th chips are short-circuited, If your log can discover the 38th chip, then there is absolutely no difficulty with the initial 38 chips. If 0 chips are still uncovered, initially Look at whether or not the 1V2 is regular.
When there is Bogus welding, it has to be re-soldered. If there is harm, it has to be measured if the resistance benefit is regular. Exchange the corresponding parts abnormally, and Test the compact board soldered about the PCB; the smaller board is demonstrated in the figure under.
In case the miner whose Command board is flashed must begin normally, the subsequent two ways are expected:
6. The repaired hash board needs to be examined using a check fixture, and it will have to go in excess of two instances for being judged as a very good products. For The very first time, right after replacing the extras, watch for the hash board to chill down, use the examination fixture to test, and when is handed, place it on one side right before cooling down. The second time, await the hash board to chill down totally ahead of tests.
In case the chip’s look will not be weakened, the chip with the lowest response level in Just about every domain should really be replaced.
When the miner that employs the Manage board flashing really should get started Generally, the subsequent two steps are essential:
a) When the LCD Screen ASIC NG: (0), 1st evaluate the full domain voltage of 21V plus the boost circuit voltage of 25V once they are ordinary. Then use a brief-circuit probe to short-circuit the RO exam point and 1V2 check point among the 1st and 2nd chips, after which run the chip obtaining program.
Open up MPLABIPE and select system: PIC16F1704, simply click electricity to choose the power provide manner, then simply click work. The first step: decide on "file" to discover the Go Here .HEX file for being programmed; the 2nd step: click on "join" to connect normally; the third phase: simply click the "method" button, and soon after completion, simply click "verify" to prompt the verification to verify that the programming is productive.
PS: Should the hashboard is not run or powered off according to the test sequence, creating R8, R9, U1, and U2 to burn off out, the chip will report 0;
This case is likely to generally be due to the irregular resistance welding from the entrance and rear CLK, CI, and BO from the Xth chip, so end users shall deal with these six resistors. The smaller chance is because of X-one, X, X+one, which is, Among the many 3 chips, the next pins abnormal welding situations with the chip manifest:
9. The exam fixtures at the upkeep close all utilize the Test_Mode method and utilize the scan code manner for screening.
Repair process: Using the dichotomy method, shorter-circuit the 1V8 take a look at position and also the RO exam position in between the 38th and 39th chips with the short-circuit probe. In case the log can discover 38 chips, there isn't a issue with the initial 38 chips; if shorter-circuiting 47 chips, although the log reports 46, it suggests that the 47th chip can't be detected, and there's no problem Together with the Visible inspection. Normally, the 47th chip shall get replaced;
It describes the troubleshooting of Bitmain Antminer S19 various faults, and describes how to utilize the check tools for precise positioning.
PS: When the hash board just isn't driven or driven off according to the check sequence, triggering U2 and U10 to burn up out, it's going to report 0 when testing the chip;
