The Basic Principles Of antminer repair
3 Around the pulse signal. Purple is B (BI, BO) signal flow,) signal circulation, from 00 chip to chip to 62 low level; no reduced degree; no low level; no reduced level; no IO line It is 0V throughout standby, and is a pulse signal of concerning 0. 3 at the time of calculation.
> Red line is the flow direction of RST signal, signal circulation instructions, signal flow instructions, from IO port 15 foot, after that from, after that from, then from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V throughout standby, and is calculated during operation.
In this Bitcoin ASIC repair stream, we have a large number of Antminer S19 hashboards from Bitmain that we need to repair. These boards ran in the harsh Texas climate in Rockdale. They burned out the TPHR90-03NL mosfets and are badly corroded on the temperature sensors and surrounding area. Most of them have completely corroded parts and pads that cause problems. Watch this stream to see how we fix these ASIC hashboards
8V when calculating. 2. 2 Number 3 reveals the key circuits on the front of the S9 hash board. figure 2. inter-chip test factors 1) examination points between each chip (After zooming in the picture below): figure 2 During upkeep, the examination factor between the examination chip is the most straight the mistake location mode of the link.
S9 Key circuits on the front of the Operation board Note that: Since the version of the S9 hash board is not precisely the exact same, the LDO-1. 8V power supply of the very early voltage domains is powered by a separate peripheral LOD power supply chip for each of the 3 here voltage domain names.
Test factors should have LCK= 0. 8V voltage, various other examination voltages is 0; 2) Plug in IO, when you do not press the test secret, DC-DC No voltage output with increase, after pressing the test trick, Picture beginning working, at this time DC-DC result PIC, Image device examination program sets the voltage, increases with the working voltage.
At this point the typical voltage of each examination factor must be: CLK: 0. 8 V, test device sends work, Carbon monoxide Since it's unfavorable. The DC level will be drawn low, Instantaneous voltage is 1.
