How to quickly repair an Antminer hash board with the 9003IB?

In the article "What is 9003IB - Integrated Board?", we introduced the functions and detailed demonstrations of the 9003IB. In this article, we will introduce what fault scenarios the 9003IB module can be used for as well as its advantages and benefits.

Since the release of the Bitmain Antminer S19 series, a common fault has often been observed, which is the failure of the MOSFET chips in the DC control circuit of the hash boards. The frequency of this phenomenon is as headache-inducing as the heat sinks were in the Antminer 17 series. Because once the DC control circuit of the hash board fails, it may damage multiple MOS chips and cause shutdown. It will take a lot of repair time to replace the chips. In serious cases, the MOS chip is impacted by overload current, and the high temperature causes the chip to burn, seriously damaging the hash board. This results in the need to hire an expert to repair it at high cost, otherwise the entire hash board or machine will be scrapped. The occurrence of these failures affected mining profits and caused huge losses to miners.

Now, the 9003 Integrated Board sold by Zeus Mining can greatly reduce the losses caused by DC circuit faults. The 9003IB module integrates multiple high-quality TPHR9003NL MOS tubes, which can be directly used to repair and replace the DC circuits of the 19 series, L7, D7, and other hash boards, providing protection circuit and chip functionality.

Why Recommend Using the 9003IB Module?

We mentioned earlier that minor MOSFET chip faults can be resolved by replacing the MOS chips, so why do we recommend using 9003IB for replacement?

This is because when replacing new MOSFET chips, the small size of the chips makes soldering relatively difficult. It requires certain welding experience or skills to complete the replacement perfectly in a short time. Moreover, after soldering, each pin of every MOS chip must be tested to ensure correct soldering and avoid short circuits due to poor contact. If need to replace MOS chips on multiple hash boards, it will consume a significant amount of time, extending downtime and reducing profits. Installing the 9003IB module does not require repair and soldering experience; you only need soldering equipment and a little solder paste to complete the job quickly and easily. It takes less time, has a high success rate, effectively improving repair efficiency and time costs, and the machine returns to operation faster.

For severe faults, such as the missing pad of the MOS chip and the DC circuit being burned, it is even more necessary to use the 9003IB module. We often see some technicians using conductive copper strips to repair such faults, and they consider it a low-cost and viable method. However, all repair experts know that this method actually poses significant safety risks. The DC control circuit functions as a switch and protector, and when the MOS chips are removed and replaced with copper strip, this design loses its protective function. The overloaded voltage and current will pass directly through the copper strip into the voltage domain power supply, which could cause chip breakdown, leading to short circuits or burning. At that time, the entire hash board could be damaged, even affecting other hash boards. Therefore, if a current shock occurs again after a copper tape repair, it could cause a larger range of faults, not reducing repair costs but causing even more damage.

Using the 9003IB can avoid such situations. The 9003IB adopts a structural design similar to the original DC circuit, achieving the role of switch control and circuit protection. Simply put, after installing the 9003 Integrated Board, even if the input voltage and current are overloaded, it will only have a certain impact on the module, and will not cause damage to subsequent circuits. In addition, the module surface uses a special coating, eliminating the need for a heatsink while still achieving good heat dissipation.

Conclusion

The 9003IB module can quickly and effortlessly perfectly repair the hash board's DC control circuit, replacing the original MOSFET chips while continuing to provide protection. It saves miners repair time, allows mining equipment to return to operation faster, extends the lifespan, and earns better mining profits. Zeus Mining suggests that both individuals and enterprises should use the 9003IB module to upgrade and repair hash board DC circuits and MOSFET chips. And it's advisable to keep a proper stock of them for quick replacements in case of sudden faults, reducing downtime and waiting.
