By the end of 2024, Bitcoin price is expected to reach $100,000! The crypto bull market is back

By the end of 2024, Bitcoin price is expected to reach $100,000! The crypto bull market is back. Bitcoin, the top cryptocurrency, could hit $100,000 by the end of 2024, according to a report by Jeff Kendrick, head of digital asset research at Standard Chartered Bank. By the end of 2024, we could see Bitcoin (BTC) reaching the $100,000 level , as we believe the much-hyped "crypto winter" is finally over. According to Kendrick, Bitcoin could benefit from many factors. For example, recent instability in the banking sector due to the end of the Fed's rate hike cycle and the increased profitability of cryptocurrency mining. As uncertainty persists, Kendrick believes the path to the $100,000 level is becoming more apparent. Bitcoin has bounced back this year, topping $30,000 for the first time in 10 months. However, the crypto industry lost trillions of dollars in 2022 after the Fed raised interest rates. Observers Are Arguing About Bitcoin Standard Chartered isn't the only

How to use antminer repair kits to repair antminer hash board?

How to use antminer repair kits to repair antminer hash board?

At present, there are practitioners engaged in cryptocurrency mining all over the world, including large farms, scattered individuals, and team-based farms. In all mining forms, ASIC miners account for a large proportion. ASIC miners will generate high temperatures during long-term operation, while ASIC chips will gradually age in high-temperature environments, reduce performance, and fail to start. At this time, we must replace the damaged chip in the hash board. Usually, there are dozens of ASIC chips in a hash board, and only 1-2, or 2-3 of them may be damaged. Then, how to accurately find these damaged chips has become a common problem encountered by repairers. In 2017, people almost all used oscilloscopes to find these bad chips, but for beginners, the use of oscilloscopes undoubtedly increased the difficulty of learning to repair. Because of this, the miner manufacturer has developed a professional Hash board testing equipment: test fixture. He locates the fault point by scanning the hash board, so as to locate the damaged chip quickly and accurately.

Hash board test fixture:

 After locating the damaged ASIC chip, in order to avoid incorrect replacement of surrounding chips, we need to use a multimeter to measure the parameters of the chip to ensure the correctness of the test. Usually, each chip on the Antminer hash board will have 5 test points: CLK, CI, RI, BO, RST (relevant data can be obtained on zeusbtc.com).

After ensuring that the above steps are correct, we can perform the chip replacement operation. Next, we need to use more professional tools:

1. Desoldering station

The desoldering station integrates the functions of a hot air gun and an electric soldering iron. The hot air gun is used to heat the Hash board in order to remove the radiator and ASIC chip (usually the chip is installed on the bottom of the radiator, and they are bonded by thermal glue or solder paste). The electric soldering iron is used to clean the residual tin dross after the chip is removed.

2: ASIC chip tinning tool

Due to the small size of the ASIC chip, many pins are arranged closely at the bottom. Therefore, we need to use professional tin-plating tools to apply solder paste to the pins of the chip, and then heat it to solidify, so as to be well fixed on the Hash board.

3: Official thermal curing thermal conductive adhesive

For bonding chips and heat sinks, official glue is recommended. If you use a third-party thermally conductive adhesive, the bonding strength may be inappropriate. Too low bonding strength will easily cause the radiator to fall off, and too high strength will not be easy to disassemble. In future repairs, the radiator is easy to tear when disassembling Split Hash board, and the official thermal conductive adhesive has the most suitable bonding strength and thermal conductivity.

4: Hash board data editor

This device is used to synchronize the data of the hash board of the miner. Its function is to repair the inoperability caused by the inconsistency of the hash board data in the miners. For example, when the hash boards of different miners are used, when the internal files of the hash board are inconsistent, the entire miner Will is not able to run, under normal circumstances, the background log will prompt "EEPROM" error. In addition, after using the test fixture to scan the Hash board, it may also cause data abnormalities. When the above situation occurs, the equipment needs to be repaired, and the scope of application: other models after Antminer s9se.

5: Necessary procedures and documents

To repair the Hash board, not only the above hardware devices but also some software or programs are needed.

E.g:

1. Test fixture file: Each miner model uses an independent test file. We copy it to the test fixture SD card to test the corresponding type of Hash board.

2. Hach board PIC file. This file is the key data of the Hach board and contains related settings such as voltage configuration. When the program fails, the Hach board will not run.

File

 

Based on the above reasons, we have assembled a repair kit. This project contains all the tools necessary to repair the Antminer Hash board, which simplifies the procurement process to a large extent. The kit has the characteristics of small size, lightweight, and easy to use. It can be used in a wide range of scenarios, including mining farms, maintenance departments, and individuals.
