7. After repairing the hash board, the thermal gel to the h2o cooling board must be taken out and reprinted.
When the examination chip will not be thoroughly detected, the board really should be repaired. If it is typical once the examination, take out the hash board separately, use the exam fixture to hold it into your Debug grasp method to mine, and alter the lover velocity to ninety five%.
(two) Once the chip however reports an integer variety just after confirming the compact board, first check if the RX sign is typical, and in addition measure whether the chip factors one.
six. The repaired hash board ought to be examined by using a test fixture, and it must go greater than two instances for being judged as a very good products. For The very first time, immediately after replacing the components, look forward to the hash board to cool down, make use of the exam fixture to test, and when is passed, place it on a person aspect ahead of cooling down. The next time, anticipate the hash board to chill down totally right before tests.
To summarize, the repair procedure for the hash board consists of regime inspection, chip take a look at, fault localization, and testing and verification. Through these steps, the faulty chip is often located and repaired or replaced, as well as the hash board can be tested to be sure it's operating properly.
(two) If the appearance on the chip is not damaged, just switch the chip with the lowest response level in Just about every area;
If there is absolutely no 3.3V output, check the relationship standing on the hash board tester cable and the hash board.
Repair system: Using the dichotomy system, short-circuit the 1V8 exam issue as well as the RO exam issue between the 38th and 39th chips Along with the brief circuit probe. Should the log can discover 38 chips, there is no problem with the very first 38 chips; if brief-circuiting the 47th chip, however the log reviews 46th, it indicates which the 47th chip can not be detected, and there's no problem Along with the Visible inspection. Commonly, the 47th chip shall be replaced;
Evaluate whether There's output on the 2nd pin of U6 plus the voltage is about 3.3V; if yes, please continue on to troubleshoot the situation; if there isn't a 3.
When utilizing the chassis to dissipate heat, 2 hashboards need to be placed at the same time to type an air duct. The single-sided check of the manufacturing should also make certain that the air duct is fashioned (vital).
two. Make the check SD card Based on the requirements, and immediately unzip the compressed package deal of The only-sided heat sink inspection chip to make the SD card;
b) If 1 chip are available in move a), it Look Here signifies that the primary chip and also the preceding circuit are good. Use an analogous process to check the subsequent chips. Such as, limited-circuit the 1V8 check level as well as RO check level in between the 38th and 39th chips. In the event the log can find 38 chips, the 1st 38 chips haven't any trouble; if you still come across 0 chips, Look at the 1V8 to start with; if it's normal, it means that there's a difficulty with the chips right after 38.
Does any info on this page appears to be like incorrect and you would like for us to examine it? Describe The problem with just as much details as feasible.
Seek advice from the voltage benefit array described from the sign craze. If the measurement encounters a large deviation of your voltage price, it can be as opposed While using the measured value of the adjacent team to determine.
