What is the 9003IB - integrated board?

Introduction

The 9003IB is an abbreviation for the 9003 integrated board, a module that integrates multiple TPHR9003NL MOSFETs. This module can be used to upgrade and repair the DC control circuit of the Bitmain Antminer S19 series hash boards, ensuring the normal power supply to the hash boards.

Applicability

Here we can see the overall appearance of the 9003IB:

The module is compact and its design structure is consistent with the DC circuit of the hash board, making it possible to replace most hash boards that use this DC circuit structure, with strong compatibility. The integrated module can repair Antminer T19, S19, S19 Pro, S19j, S19J Pro, S19A, S19A Pro, S19AL, S19+, S19i, S19 PRO+, S19J PRO+, L7, D7, and others.

Appearance details

Next, let's take a look at more details of the 9003IB:

The 9003IB module is soldered with 6 high-quality TPHR9003NL MOSFET chips. These N-channel MOSFETs act as switches on the Antminer hash board. Without these chips as switches, the other circuits and chips on the hash board would lose a layer of protection. If the input voltage and current are overloaded, it could impact the connected components and performance. The 6 MOSFET chips effectively act as switches and protectors, extending the life of the hash board.

There is also a cable on the 9003IB module, which is used to connect to the boost circuit of the hash board. On the S19 series hash boards, the DC control circuit not only acts as a switch and protector but also provides input voltage for the boost circuit. Therefore, a cable is prepared here to power the boost circuit.

The 9003 Integrated Board is manufactured with high-end instruments; its core and surface are equipped with special materials, and after multiple tests, it has good heat dissipation effects. Therefore, after installing the 9003IB module to repair the DC circuit, there is no need to install a heat sink, and there is no need to worry about the heat dissipation effect.

The PCB of the 9003IB module uses a 4-layer board material, which is of higher quality compared to the 2-layer board material of ordinary control boards, making it less likely to be damaged and easier to store and transport.

Here, we install the 9003IB module on the hash board that needs to be repaired. As you can see, after removing the MOSFET chips from the hash board, you only need to solder the two ends of the module with solder paste to the conductive copper strips, and connect the cable to the boost circuit to complete the repair of the DC circuit. The installation is very simple and convenient, with low requirements for soldering skills, allowing even beginners to quickly and easily complete the process. It can effectively help technicians save soldering time, improve repair efficiency, and restore the hash board more quickly.

Test confirmed

After replacing the original DC circuit with the 9003IB module, it is necessary to verify the circuit. The test results show that the 9003 Integrated Board has the same functions as the original DC circuit, including switch control and protection, restoring the power supply to the hash board.

Conclusion

The 9003IB is an essential accessory for repairing Antminer hash boards, capable of quickly and easily resolving DC circuit faults and restoring DC circuit functions. If you own a Bitmain 19 series, L7, D7, or other ASIC miners, it is recommended to upgrade with the 9003IB module or keep it as a spare part for repairs.
