4mm); when changing a whole new chip, you need to tin the chip pins and after that solder to your hashboard, and afterwards lock massive warmth sinks immediately after making use of thermal gel evenly to the chip area.
To check repairing and changing the chip, take a look at the chip very first after which do the practical examination after it passes. The functional take a look at must be certain that the modest heatsink is welded effectively, the big heat sink is installed, as well as thermal adhesive gel is used evenly.
8V, one.8V patch filter capacitors (evaluate the resistance on the patch filter capacitors connected to the back and front with the PCBA)
Evaluate whether the domain voltage is usual. Typically, the domain voltage might be irregular in the problematic domain. Then evaluate the RI signal to determine Should the RI sign is damaged. If the RI sign is lacking, mainly, the chip is short-circuited or damaged immediately after becoming tinned.
9. When replacing a whole new chip, clean up the pins and implement solder paste in order that the chip is coated with tin in advance of soldering.
Not long ago, quite a few providers proclaiming to become mining providers imitate us and say that they are related to us, or that they are our branch companies, which has induced consumers to be deceived.
Be a part of the global community of miners who belief minerstat to elevate their mining video game. Are you presently all set to unlock your mining opportunity?
The repaired hash board might be judged as a superb product or service with over two passes when analyzed Along with the hash board tester.
PatternNG is brought on by the big distinction between the characteristics on the chip along with other chips. At this time, it really is identified which the chip die is broken, so just replace the chip. In accordance with the log details, the alternative regulations are as follows:
(2) U1 can't be made use of on other number of styles In case the OTP perform is enabled to the Command board.
Does any info on this page seems incorrect and you want to for us to examine it? Clarify The difficulty with just as much data as possible.
If there isn't any problem Using the relationship, Purchase Here you can execute the PT2 take a look at on The one board to check whether the take a look at can go. If it might be passed, most probably the Manage board is faulty. In the event the test fails, utilize the PT2 upkeep technique to repair.
② The next situation: Micro-brief circuit concerning indicators (0-hundreds of ohms), because of the compact resistor price of the chip pins, 1st utilize a warmth gun to solder and see if it is OK;
two) Less website link: A lot less backlink refers to that Amongst the three boards, one piece is missing. Typically, You will find there's issue Together with the relationship in between the hashboard plus the Management board. Test the cable to see when there is an open up circuit.
