Antminer T19 necessary maintenance equipment:

1. Test tool requirements:

APW12 power supply (APW12_12V-15V_V1.2 and power adapter cable, used for power supply to the hash board use; control board, hash board test fixture, the positive and negative poles of the test fixture need to be installed with discharge resistors, it is recommended to use a cement resistance of 25ohms, 100W or more.

2. Maintenance auxiliary materials/tools requirements:

Solder paste, flux, circuit board cleaning solution, and anhydrous alcohol; circuit board cleaning solution is used to clean up the flux residue after repair; the thermal paste is used to apply on the chip/heat sink after repair (some models need to use thermal paste ); tin tool, tin removal wire, and solder ball; when replacing a new chip, it is necessary to plant tin on the chip pins, and make a shortcircuit pin, which is used for maintenance.

3. Common maintenance spare material requirements:

0402 Resistor (55R and 10K); 0402 Capacitor (0.1uf, 1uf)

Antminer S19 necessary maintenance equipment:

1. Test tool requirements:

APW12 power supply (APW12_12V-15V_V1.2 and power adapter cable, used for computing board power supply; use the test fixture of V2.2010 control board. The positive and negative poles of the power supply of the test fixture need to be installed with discharge resistors. It is recommended to use 25 ohms, 100W above the cement resistance.

2. Requirements for maintenance auxiliary materials/tools:

Solder paste, flux, board washing water plus absolute alcohol; board washing water is used to clean up the flux residue after maintenance; thermal gel (specification: Fujipoly SPG-30B) is used to apply on the surface of the chip after maintenance ; tin Tool, tin suction wire, solder ball (the ball diameter is recommended to be 0.4mm)> When replacing a new chip, it is necessary to solder the chip pins to the hashboard, before soldering to hashboard, and evenly apply thermal gel on the chip surface before locking Large heat sink.

1) Scanning gun
2) Port adapter board RS232/TTL adapter board 3.3V
3) Self-made short-circuit probe (use pins for welding, need to heat the shrink tube to prevent short-circuit between the probe and the small heat sink)

3. Common maintenance spare material requirements:

0402 resistors (OR, 51R, 10K, 4.7K,); 0402 capacitors (0.1uf, 1uf)
