Canaan Technology Launches New Avalon A13 Series Bitcoin Miners

Canaan Technology Launches New Avalon A13 Series Bitcoin Miners According to the latest news, Canaan Technology announced the launch of the new Bitcoin miner Avalon Made A13 series, including Avalon A1346 and Avalon A1366. Canaan Technology said that the new generation of miners uses advanced ASIC technology, and the A13 series will include two different models. Compared with the 90 to 100TH/s hash rate offered by the A12 series, the A13 series has both hash rate, and energy efficiency has been enhanced. Canaan's CEO said the all-new A13 is a milestone in the company's over-computational energy consumption analysis. The model A1346 has a hash rate of 110 TH/s and an energy efficiency of 30J/TH. Model A1366 has a hash rate of 130TH/s and an energy efficiency of 25J/TH. Comparing the energy efficiency ratio of Bitmain's flagship S19 XP of 21.5 J/TH with that of Bitmain's M50S of 0.026j/Gh, the new series of A1346 is "very competitive" in terms of efficiency at

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

How to use Antminer BM1387 tin tool to replace damaged chips?

How to use Antminer BM1387 tin tool to replace damaged chips? In the repair work of the h ash board, the most common problem is to replace the ASIC chip, which  is the most easily damaged part of the h ash board. In this article, I will use A ntminer as an example to show my friends how to use Antminer BM1387  tin tools to replace damaged chips?  Although there are many chip models, most of the pin positions and sizes are the same. ASIC chips are usually small in size and the pins are arranged closely, which brings great difficulty to maintenance and replacement. Because when replacing a new ASIC chip, it is necessary to accurately apply solder paste on each tiny pin, then heat it to melt, and finally fix it on the h ash board. For how to solve this problem, after various attempts, we finally chose a convenient and efficient way: making professional tin tools (ASIC tin tools). Its principle is to fix the chip on the base, then use a special steel mesh to align the pins of the chip, and
