PatternNG is a dilemma that occurs because of substantial discrepancies in the characteristics of a specific chip as compared to other chips. To resolve this situation, it's been determined that the chip’s die is broken and desires to be replaced.
two. For The very first time make use of the 19 collection examination fixture SD card flash method to update the FPGA Command board from the tester, copy it into the SD card just after decompression, and insert the SD card in the fixture card slot: Power on for around 1 moment, and wait for the red and green indicators on the Management board to flash three occasions in succession, then the update is finish (if it is not updated, it might lead to a set chip to get noted as defective throughout the check).
Immediately evaluate the domain voltage to Identify the problematic area, or utilize the 1V8 and RO quick-circuit approach to Track down the abnormal place.
Evaluate if the domain voltage is normal. Typically, the domain voltage will probably be abnormal inside the problematic area. Then measure the RI signal to discover if the RI sign is broken. If the RI sign is missing, basically, the chip is brief-circuited or ruined soon after becoming tinned.
one. Pay attention on the operation approach when changing the chip. Following replacing any extras, the PCB board shall haven't any obvious deformation.
● When locating the faulty chip, the chip ought to be welded once again. The method is so as to add flux round the chip (preferably no-clean flux), and heat the solder joints in the chip pins to some dissolved condition to prompt the chip pins and pads to re-operate in and gather the tin, In order to achieve the influence of tinning once again. If Antminer s19 Pro Hashboard the fault continues to be the same immediately after re-soldering, it is possible to right switch the chip. ● The repaired hash board can be judged as a superb product or service with greater than two passes when screening While using the hash board tester. For the first time, just after changing the sections, watch for the hash board to chill down, utilize the hash board tester to check, and once the examination is handed, set it aside after which you can awesome it down. For the 2nd time, right after a few minutes when the hash board cools down, examination once more. 0 About items invest in, you should Make contact with our gross sales supervisor:
The following fault examples are from Antminer 19 collection mining machines, other Antminer styles are for reference only.
The repaired hash board might be judged as a very good products with in excess of two passes when tested Together with the hash board tester.
① After the card is swiped successfully, the eco-friendly LED indicator is always on, and the facility is turned off and restarted at the moment;
When using the chassis to dissipate heat, 2 hashboards must be put at the same time to kind an air duct. The only-sided examination of the manufacturing must also be sure that the air duct is shaped (essential).
a) Following the card Restoration is passed, the environmentally friendly LED indicator are going to be often on, and the ability shall be restarted;
3. When sensor NG is displayed about the LCD display in the fixture, the examination looking through temperature is irregular. You should follow the ways below to troubleshoot:
It describes the troubleshooting of Bitmain Antminer S19 numerous faults, and explains how to use the test applications for precise positioning.
