4mm); when replacing a whole new chip, you need to tin the chip pins and then solder for the hashboard, and afterwards lock big heat sinks just after making use of thermal gel evenly on the chip floor.
This spare section is specially suitable for uncomplicated routine maintenance and repair of your S19 Professional hash board, making certain seamless operations and superior-effectiveness mining.
In the case of a specific chip currently being fixed, look for abnormal resistance welding with the front and rear CLK, CI, and BO of your Xth chip. If your test time is sort of twice as long as the good board, it could point out a difficulty with soldering.
(three) Irregular temperature: The utmost PCB temperature established by our checking process are unable to exceed 90C/194T.
Join the worldwide Neighborhood of miners who rely on minerstat to elevate their mining activity. Are you currently all set to unlock your mining prospective?
Or The 2 ASIC chips in this area are usually not soldered effectively. Many of them are due to brief circuit of 0.8V and one.2V patch filter capacitors (measure the resistance on the patch filter capacitors associated with the back and front sides from the PCBA).
Kernel Log: it keeps documents of ANTMINER's operation phases, which serves as a means to troubleshoot some popular concerns. The strategy to enter the miner log: enter the miner IP tackle from the handle bar of Google or Firefox browser >> enter the consumer title/password (default root/root) >> the miner log
2. Soon after there aren't any challenges in plan testing (limited circuit detection in program testing is usually necessary to avoid burning the chip or other products as a result of brief circuit when ability is on), the take a look at fixture may be used to detect the chip, along with the positioning is usually determined according to the exam fixture detection outcomes.
(2) Use the take a look at fixture of your V2.1010 Manage board (its product is ZJ0001000001), the favourable and negative poles of the power source of the check fixture have to be installed using Price Here a discharge resistor, and it is suggested to use a cement resistor of 25 ohms and above 100W.
(two) Next, if there isn't any difficulty soon after visual inspection, you can initial test the impedance of each and every voltage area to detect irrespective of whether there is a short circuit or open circuit. If identified, it have to be handled initial.
● When locating the faulty chip, the chip must be welded once again. The method is to add flux across the chip (ideally no-clean up flux), and warmth the solder joints of your chip pins to the dissolved condition to prompt the chip pins and pads to re-operate in and accumulate the tin, so as to accomplish the effect of tinning once more. In case the fault stays exactly the same following re-soldering, you'll be able to immediately exchange the chip.
minerstat is not just A different calculator - It can be a robust mining System that supports your copyright journey. Improve your revenue, help save important time, and optimize performance with our suite of quality options:
② The second situation: Micro-shorter circuit concerning indicators (0-a huge selection of ohms), because of the modest resistor worth of the chip pins, first use a heat gun to solder and see whether it is Alright;
a. Check out whether the warmth sink with the hash board is adhered to by foreign objects such as dust, catkins, insects, etcetera. The dust accumulation about the hash board will trigger weak heat dissipation, and it ought to be cleaned and cooled before turning around the miner.
