We've been gradually using Hong Kong as a business Middle for Office environment exchanges to serve overseas consumers at any time. We have our own upkeep group and professional graphics card device mining scheme, which could give shoppers Qualified mining recommendations.
Following the mend and alternative chip tests, it is important to perform a complete chip Test right before proceeding on the functional exam. The practical check must make sure the double-sided heat sinks are soldered the right way and that the cooling lover is running at whole pace.
In the course of the measurement and servicing of the back and front on the hash board, the steel windshield must be underneath 21V voltage. It is important to maintain the maintenance desk clean and insulated to prevent any short circuits throughout upkeep.
You'll have to shorter the signal and find out when the tester won't react, to continue thus by elimination and to replace the faulty chip.
When screening the voltage, we need to contact the black pen with the multimeter towards the GND as well as the crimson pen to five check points. You should utilize the ARC Tester to begin the hash board and examination it while it really is Operating.
When replacing a chip, it is vital to pay for near notice for the Procedure technique to avoid any evident deformations in the PCB board. It's important to look for any open up or small circuits, or missing components from the substitution parts as well as their environment.
You will Antminer z15 control boar find 26 voltage domain constant recent chips on the whole board, distributed beneath the warmth sink within the reverse facet in the hashboard. The functionality of the element would be to stabilize the voltage and supply a preset starting existing to your voltage domain where it is found.
Instructors ought to full at least four hours of teaching methodology classes. 8 hrs might be received by means of these hrs.
The voltage checking chip is found over the upper remaining aspect on the front in the hashboard. The main operate on the voltage checking chip is to watch the actual-time voltage from the voltage area of the hashboard.
Following, the impedance of each and every voltage area should be examined to detect any shorter circuits or open circuits. If any this sort of troubles are discovered, they have to be handled straight away. The technician also needs to make sure that the voltage of each area is about one.6V.
Re-electricity the hash board and Verify if the boost output is regular. The test result is about 18V, indicating the Strengthen module has been changed correctly.
You will find 4 T451 temperature sensor chips on The full board, which are located about the backside in the hash board. The temperature sensor chip is under the heatsink about the reverse aspect, and the radiator should be disassembled to be identified.

There are actually a total of thirty BM1397 chips on The full board. They may be dispersed beneath the front heatsink and linked to the heatsink throughout the thermosetting adhesive.
