Almost certainly, the IP can not be discovered resulting from abnormal Procedure. Seek advice from the very first stage for troubleshooting.
Repair system: Look at the looks, measure the chip capacitor or resistance in front, typically It really is because of very poor chip soldering or simply a chip capacitor, resistor detrimental or abnormal resistance;
Just before tests the sample, the repaired hashboard have to cool down prior to testing; in any other case, it's going to bring about testing NG.
8V starting from the very first chip. In the event the serial port stops long-expression operation after the shorter circuit, the very first chip is functioning thoroughly.
8V, 1.8V patch filter capacitors (measure the resistance of your patch filter capacitors connected with the front and back on the PCBA)
● When finding the defective chip, the chip should be welded again. The tactic is to incorporate flux within the chip (ideally no-clear flux), and heat the solder joints of the chip pins to a dissolved state to prompt the chip pins and pads to re-operate in and collect the tin, so as to realize the result of tinning all over again. Should the fault stays precisely the same following re-soldering, you may specifically change the chip.
Windows mining Our mining checking and administration software package for Home windows GPU rigs is the best Remedy for many who choose to mine on their Home windows devices.
two. Enter the consumer identify, password and check command to examine the NONCE reaction standing as well as status of voltage domain. In case the NONCE and domain voltage are abnormal, person can perform measurement and servicing according to the printed abnormal chip.

2. The upkeep operators should have selected electronic understanding, more than one yr of upkeep knowledge, and become proficient in BGA/QFN/LGA offer soldering technologies. three. Soon after repairing, the hash board should be examined for greater than two occasions to get Alright in advance of it may go! 4. Check if the tools and hash board testers can function Ordinarily, determine the maintenance station to check program parameters, examination fixture variations, etcetera. 5. From the test of repairing and changing the chip, the chip must be tested first, after which Buy Here the function check shall be carried out after passing. The purpose exam should make sure the smaller warmth sink is welded skilled. When setting up the big heat sink, the surface from the chip need to be evenly coated with thermal gel and the cooling fan shall be at whole speed. When using the chassis to dissipate warmth, two hash boards really should be positioned simultaneously to sort an air duct. The one-sided take a look at with the manufacturing should also make certain that the air duct is formed (significant). 6. When measuring the signal, use four supporters as aid for heat dissipation, and also the admirers shall keep comprehensive speed. seven. When powering on the hash board, person have to initial link the adverse copper wire of the power provide, then the beneficial copper wire of the ability source, and finally plug during the signal cable. When eliminating, the purchase of installation has to be reversed. First take away the sign cable, then remove the beneficial copper wire of the facility supply, And eventually eliminate the adverse copper wire of the power offer. When the user usually do not abide by this purchase, it is rather very easy to cause damage to R233, R232 (not all chips can be found). Just before testing the pattern, the repaired hash board have to be cooled down right before testing, otherwise it may trigger PNG. 8. To switch a new chip, printing pins and soldering paste are needed in order that the chip is pre-soldered then soldered to your PCBA for repair III. hash board Tester Generating and Matters Needing Focus The supporting fixture with the hash board tester need to satisfy the warmth dissipation in the hash board and aid the measurement of indicators. 1. When utilizing the 19 Pro test fixture for the first time, you might want to use FPGA (generate conversion file) to update the examination fixture to decompress the fpga file, copy many of the data files towards the SD card, then insert it in the examination fixture card slot, power on for around 1 moment, and look forward to the instruction mild flashes in excess of 3 situations to complete the update, then eliminate the SD card. Be aware: If your update isn't accomplished, it might bring about the test fixture to prompt exactly the same chip mistake every time. 2: Please instantly decompress the conversion file and copy it for the SD card. (You should structure the SD card in advance of copying)
If any problems come up in the course of the examination, they should be repaired in accordance with the monitoring interface and the exam LOG prompts. The maintenance techniques to the Preliminary exam plus the growing old exam of The full machine are a similar.
