In the repair work of the hash board, the most common problem is to replace the ASIC chip, which is the most easily damaged part of the hash board. In this article, I will use Antminer 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 hash 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 then apply the solder paste to the steel mesh. The solder paste will penetrate into the pins of the chip along the customized small holes of the steel mesh. Remove the stencil and heat the solder paste on the pins of the chip.
Method and principle of using:
1: Fix the ASIC chip on the base.
2: Place the ASIC tin tool steel plate on the base.
3: Pay attention to check whether the chip pin position is accurate.
4: Apply solder paste to the steel plate.
5: Take out the chip and heat it until the solder paste melts. After cooling, it can be installed on the hash board.
Feature description:
At first, people used aluminum alloy materials to make tin tools but later discovered that such materials are very easy to generate static electricity on the package shell of the chip, and it is easy to damage the ASIC chip during the replacement process. Therefore, after many repairers have replaced the new chip, the Hash board still cannot run. This is most likely because the new chip has been damaged. Therefore, after research, we adopted the most stable but relatively high-cost carbon compound as the material and re-developed a new tin tool, which has more wear resistance, high-temperature resistance, and anti-static characteristics.
If the custom stencil is offset, you can adjust it with the 6 screws on the front. In addition, you can also replace the custom stencil by removing these 6 screws.

Important parts of ASIC miners — Hash board
One Antminer consists of 3 to 5 Hash boards, a control board, a casing, and software, among which the Hash board is easiest to broken. Because the ASIC bitcoin miner hash board consists of many serially connected ASIC chips. When they work, they will be in a high-temperature environment for a long time. In this environment, it is easy to burn the chip or scatter the solder due to high temperature which makes the hash board or the mining machine unable to work and no hash rate.
How to quickly detective which chip broken? It’s the most important when we repairing ASIC miners.
The Antminer chip fixture is a fast, efficient, and easy-to-use Bitmain Antminer maintenance inspection tool.

In the practice of hash board repair, the most difficult thing is how to accurately find the damaged ASIC chip, because the chip is usually located under the heat sink and impossible to observe with our eyes, so we can only rely on equipment for detection.
In the past when people who offering Antmienr repair service to test and read via waveforms to judge chips damaged or not. But this method needs professional electronic knowledge or you will see it’s very hard. Even you are enough professionally but the accuracy of this method will produce some errors and hard to founding damaged chips.
Antminer hash board tester — Antminer chips fixture comes out.
To better simplify the operation process and improve work efficiency, a Chinese company has developed a professional Hash board inspection tool called Antminer chips fixture or Antminer test fixture or Antminer tester. It completes the detection work by scanning the chips of the entire hash board, with simple operation and high precision.
The test result will be directly displayed on the computer screen and the status of the hash board can be understood more intuitively, including the number of chips, hash rate, temperature value, calculation of the method, and other parameters.
If the chip on the Hash board is bad, the test fixture will stop sending signals when scanning the chip and prompting the chip number. Next, we only need to test the voltage and resistance of the chip with a multimeter to determine whether it is damaged, and then replace it.
How to use Antminer chips fixture to lock the damaged chips
let’s start with the ASIC miner Antminer s9 hash board for an example. Before starting the test, we need to install the USB driver and test software on the computer. Then connect the USB interface of the test fixture to the computer and perform the correct port configuration. After completing these steps turn on the power to the test fixture. At this point, the computer screen will show some progress. This is the self-check procedure of the test fixture. The Hash board can only be tested after the self-check is completed.
When testing the Hash board, we need to connect the 12V power supply to it then connect the data cable of the chips fixture to the Hash board then press the “Test” button of the test fixture to start testing. At this time, will display the test progress and display key parameters on your computer screen. usually, the test process runs to the end and displays 2–3 “OK”, which means that the Hash board can be work and chips not damaged.
In the testing, if you saw “No Hash Board” on the computer screen, it means the test fixture cannot recognize the Hash board. Please check the connection of the data cable and power input. If the above two points are normal, you need to use a multimeter to check whether the voltage of the hash board voltage is normal and whether the voltage of the MOS chip is normal. If the computer screen prompts “0 chips detected”, it means that the chip has not been recognized, please check the first and last chip, because these two chips are responsible for the initial signal transmission and signal return when one of them has a problem. When this happens, there will be no signal on the entire Hash board. If the chip number is prompted on the computer screen, such as “23 chips detected”, it means that the 22nd chip has problems. This is due to the signal sending direction. When the 22nd chip is damaged, the detection signal will stop between the 22nd and 23rd chips, so the test fixture will prompt 23 errors. It is recommended to use a multimeter again to check the voltage and resistance of the 22nd chip and determine whether it is damaged. This situation is very common.
Huge demand and high profit
Once you have mastered how to repair the hash board, you can open a store and offer Bitmain miner repair local repair services. Like the united states, the Antminer repair service is very popular. When you mastered this skill you will get a high profit.

Antminer Parts and Tools
Notice:
When we tested different hash boards, the TF card of the Antminer test fixture needs to be replaced. TF cards have different types of built-in test files, and the basic files for running test programs vary from chip to chip. For example, the architectures of 1387, 1396, and 1397 chips are different, so they will have three versions (that is, three conversion files).
When testing the Hash board of different chips, you need to refresh the corresponding conversion file in advance, and then insert the test file of the matching TF card.
