How to correctly install the 9003IB MOS module?

9003IB integrated boards are used in Antminer hash boards to protect DC circuits and are designed to replace the 9003 MOS chip, simplifying maintenance without requiring time-consuming soldering. They ensure optimal performance of hash boards such as Antminer S19 series, T19, D7, L7, Iceriver KS3L, etc.

9003IB MOS module installation tutorial:

1. Confirm that the 1st pin of the 9003 MOS chip on the module is in the same direction as the 1st pin of the TPHR9003NL chip on the hash board.

2. Remove the heat sink on the back of the hash board, and then remove several TPHR9003NL MOS chips on the front.

3. Apply solder paste to the back of the 9003IB board (Attention: the solder paste only needs to cover the area in contact with the copper plate of the hash board).

4. Place the 9003IB module in the correct position as shown. Then, press the module gently with tweezers and use a hot air gun to melt the solder paste. After that, we need clean the module when it cools down.

5. Finally, solder the cable on the module to the negative pole of the Zener diode on the back.

The 9003IB integrated module is an essential accessory for repairing Antminer hash boards, quickly and easily solving DC circuit failures. Restore DC circuit function, extend the miner's service life, and get better mining benefits.
