9003IB MOS chip Integrated board

9003IB MOS chip Integrated Board DC Control Circuit Module

9003IB MOS chip Integrated board is used to replace 9003 MOS chips that have failed hashboards such as S19 T19 D7 L7.

9003IB is the abbreviation of 9003 MOS chip Integrated Board. This module integrates 6 pieces of the TPHR9003NL MOS chip. Using the 9003IB module, the hash board's DC control circuit, ASIC chip, and LDO chip can be effectively protected. 9003IB integrates MOS tubes and precision resistors. The most important and useful is during maintenance, you only need to weld the integrated board. It is simple to operate and does not require time-consuming welding of MOS tubes. It shortens maintenance time and downtime, can be put on the shelf quickly, and increases mining profits.

Note: 

1. This product is jointly developed and has sales channels in Russia. Therefore, our company's 9003IB is not sold in Russia.

2. This product is protected by copyright, has undergone long-term stability testing after successful development, and has been put into market use. Recently, we have discovered that counterfeit products have appeared on the market. The counterfeit products have caused some customers' hash boards to burn out due to the use of inferior MOSFETs, poor heat dissipation, and lack of long-term testing. Please pay attention to distinguish the authenticity before purchasing.

9003 Integrated board applicable environment:

1. When the hash board has problems such as pad detachment, breakdown, burnt, MOS tube abnormality, or failure to work properly, replacing the 9003IB integrated board can effectively protect the ASIC chip and LDO chip, etc., and avoid abnormal voltage and current from damaging a large number of components, causing damage to the entire hash board. In the case of abnormal voltage and current, if you choose to use or replace the integrated module, it will only damage the integrated module and will not damage components such as ASIC chips and LDO chips.

2. If it is a normal working hash board, choosing the 9003IB board for upgrade and modification is recommended. When abnormal voltage and current occur, it will only burn or break down the 9003IB integrated board, thus protecting other circuits and components of the hash board. The circuits of the miners on the mining farm are all connected in series. If the hash board DC circuit of a single miner is burned out due to abnormal voltage and current, it may cause the same fault to occur to most miners, unable to work normally or even shut down;

Applicable Model:

Antminer 10+ hash boards: T19, S19, S19pro, S19j, S19J pro, S19A, S19A pro, S19AL, S19+, S19i, S19 PRO+, S19J PRO+, L7, D7. etc.

Advantages of 9003IB Integrated Board:

1. Use multiple imported MOS tube chips: high quality, stable performance, long service life, not easy to damage;

2. Efficient heat dissipation: The 9003IB module surface adopts a special coating and has its heat dissipation function, which can dissipate heat more efficiently without welding the heat sink;

3. Welding is simple and fast: It takes at least 30 seconds for a senior maintenance master to weld a MOS tube and requires welding skills. If the welding is poor, it will cause damage again after power is turned on. When multiple MOS tubes are damaged, the repair time will be longer. The 9003IB module is simple and fast to weld and can be easily fixed using solder paste or tin wire, which can greatly save maintenance time;

4. Strong compatibility: suitable for various Antminer hash board models;

5. Protection circuit: Installing conductive copper sheets will cause the DC circuit to lose its protection function, causing subsequent circuits and even the entire board to burn out, increasing the chance of the entire machine being scrapped. Soldering and installing the 9003 Integrated board returns the DC circuit to normal and protects the hash board.

After repeated tests, it has been verified that using the 9003IB Integrated Board to repair hash board DC circuit faults is convenient and fast, improves maintenance efficiency, reduces the time when the miner is taken off the shelf, and thus obtains more mining profits. Especially for mining farms with large quantities of mining equipment, stocking 9003IB inventory can greatly reduce corporate losses.

How to install the 9003IB MOS module?

1. Confirm that the first pin of the hash board MOS tube is in the same direction as the first pin of the 9003IB MOS tube.

2. Remove the hash board TPHR9003NL MOS chip and the heat sink on the back of the MOS tube chip.

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

4. Install 9003IB to the hash board (refer to step 2 for installation directions)

5. Use a hot air gun to melt the solder paste. You can use flux oil to help melt it, and tweezers gently press the module. When you see melted solder paste overflowing from the gaps in the module, it means the installation is successful.

6. Connect the cable to the negative terminal of the Zener diode.

7. Finally, you can use Mechanic 500 lead-free circuit board cleaner to clean the residual soldering oil and solder paste on the surface of the module.
