Which components of the Antminer T17 hash board are easily damaged？

Which components of the Antminer T17 hash board are easily damaged ？ T17 hash board (BHB07601) has a total of 30 BM1397AG chips . It adopts double-sided heat dissipation (there are heat sinks on both sides of the hash board). And during long-term continuous operation, some components will easily fail. The easily damaged electronic components of the hash board are described as follows. Schematic diagram of T17 hash board: front, the heat sinks have been removed, this type of heat sink  is soldered to the chip by solder paste, visible ASIC chip. Schematic diagram of T17 hash board: back, the heat sink is fixed on the hash board with soldering paste.   Easily damaged part 1: ASIC chip (BM1397AG) There are a total of 30 BM1397AG chips on the whole board. They are distributed under the front heat sink and connected to the heat sink through the thermosetting adhesive. In daily maintenance, ASIC chip damage is widespread.

Antminer s9 profitability

Antminer S9 profitability Now, Cause of Antminer s9 hash rate when we use it to mining SHA-256 cryptocurrency the profit is getting very low, but if your electricity cost is very cheap, I think this miner is your best choice for mining bitcoin. S9 here is a series including S9 S9K S9J S9se etc. but even them the profit is low too, but as I said the electricity cost and this ASIC miner price is the thing you need to consider this miner suitable us or not. How to get Antminer s9 warranty service and repair parts For now, the Bitmain company stops maintenance of Antminer s9 series miners, but this is not a major thing because you can purchase the ASIC miner parts and repair service and tools from us or other places. About Antminer s9 overclock firmware program So, we have the cheap electricity bill and repair warranty now. what do we do for now? the overclock firmware! You can buy it or download it for free.

Antminer S9 hash board Antminer S9 hash board power supply unit Voltage and ground value test of Antminer S9 power supply unit 12V voltage test Test method: adjust the Fluke 15B+ multimeter to the DC gear; the red test lead is placed on the positive pole of the power interface of the hash board, and the black test lead is placed on the negative pole of the power interface. PIC chip voltage test There is a white dot next to the PIC chip, which is 1st Pin. Test method : Adjust the Fluke 15B+ multimeter to the DC gear, measure whether the 1st Pin of the PIC chip has output, and the normal voltage is about 3.3V. If there is no 3.3V, please check the connection status of the hash board test line to see if the hash board is normal; if not, you need to re-program the PIC.

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

What is the Antminer BM1489 ASIC chip?

What is the Antminer BM1489 ASIC c hip? Antminer  BM1489 ASIC chip is an ASIC chip on the Bitmain Antminer L7 hash board for mining Litecoin and Dogecoin. In the integrated circuit industry, an ASIC is considered an integrated circuit designed for a specific purpose. The characteristic of ASIC is to design and manufacture special integrated circuits according to user requirements. The chips used for mining are called ASIC miner chips. Compared with general-purpose integrated circuits, ASICs have the advantages of smaller size, lower power consumption, improved reliability, improved performance, enhanced confidentiality, and reduced mass production costs. In terms of mining hash rate, ASICs are tens of thousands of times or higher than contemporary CPUs and GPUs, so ASIC chips on the market are also more popular than them. Image courtesy of ZEUS MINING For example, Bitmain Antminer L7 , which is currently sought after by the market, is a standard ASIC miner, and it is the best choice f

What are the common procedures for repairing Antminer L3+ hash board?

What are the common procedures for repairing Antminer L3+ hash board? Common repair process 1. Routine inspection: First of all, visually inspect the hash board to be repaired to observe whether there is any displacement, deformation, or scorching of the small heat sink? If any, you must deal with it first; if the small heat sink is displaced, remove it first, wash off the original glue, and re-adhesive after the repair is passed. Secondly, after the visual inspection is no problem, the impedance of each voltage domain can be tested first to detect whether there is a short circuit or an open circuit. If found, it must be dealt with first. Thirdly, check whether the voltage of each voltage domain reaches 0.8V, and the voltage difference of each voltage domain shall not exceed 0.05V. If the voltage of a certain voltage domain is too high or too low, the circuits in the adjacent voltage domain generally have abnormal phenomena. Need to investigate the reason first. 2. After the routine te

How to check and replace ASIC miner cooling fan and PSU cooling fan？

How to check and replace ASIC miner cooling fan and PSU cooling fan？ Miner fan or PSU fan is almost the most vulnerable component because of the continuous work of miners. High-strength and high-speed working methods can easily cause damage to its bearings and internal coils. When the fan is damaged, the miner or PSU will lose heat dissipation and cannot work or damage the chip. Therefore, regular inspection and replacement of bad fans is an essential job of maintaining miners. Both ASIC miners and GPU miners use a large number of cooling fans. Depending on the device model, the fan specifications used are also different. Normally, the most common fan sizes are: 4cm, 6cm, 12cm, 14cm. The standard voltage is 12V, the current is 0.27A to 7.2A, and the power cord is 2 to 6 pins. The specific size of the fan to be selected needs to be determined according to the device. When these fans fail, it isn't easy to detect from the appearance because one piece of equipment is equipped with 2 t
