The smart Trick of antminer repair That No One is Discussing
3 Around the pulse signal. Purple is B (BI, BO) signal circulation,) signal flow, from 00 chip to chip to 62 low level; no low degree; no reduced level; no reduced degree; no IO line It is 0V during standby, and also is a pulse signal of regarding 0. 3 at the time of computation.
> Red line is the flow direction of RST signal, signal circulation instructions, signal flow instructions, from IO port 15 foot, then from, after that from, after that from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V throughout standby, and also is computed throughout procedure.
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 read more these ASIC hashboards
8V when determining. 2 Number 3 reveals the key circuits on the front of the S9 hash board.
S9 Key circuits on the front of the Operation board Note that: Because the version of the S9 hash board is not precisely the same, the LDO-1. 8V power supply of the early voltage domain names is powered by a separate outer LOD power supply chip for every of the three voltage domains.
8V, DC-DC Outcome as well as boost 14V Voltage. Detection technique: 1) Do not plug IO line, plug only 12V: DC-DC result is around 9V, the boost output voltage is around 14V. Examination factors should have LCK= 0. 9V, RI =1. 8V voltage, other test voltages is 0; 2) Plug in IO, when you do not press the test trick, DC-DC No voltage output with increase, after pushing the test secret, PIC begin functioning, at this time DC-DC result PIC, PIC device test program sets the voltage, climbs with the working voltage.
At this point the normal voltage of each test point need to be: CLK: 0. 8 V, test device sends work, Carbon monoxide Due to the fact that it's adverse. The DC degree will be pulled reduced, Immediate voltage is 1.
