Details, Fiction and hashboard repair
3 Around the pulse signal. Purple is B (BI, BO) signal circulation,) signal flow, from 00 chip to chip to 62 reduced level; no low degree; no reduced degree; no reduced level; no IO line It is 0V throughout standby, and is a pulse signal of about 0. 3 at the time of calculation.
> Red line is the flow direction of RST signal, signal flow direction, signal flow direction, from IO port 15 foot, after that from, then from, then from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V throughout standby, and is computed throughout 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 computing. 2 Figure 3 reveals the vital circuits on the front of the S9 hash board.
S9 Key circuits on the front of the Procedure board Note that: Since the version of the S9 hash board is not specifically the same, the LDO-1. 8V power supply of the early voltage domains is powered by a separate peripheral LOD power supply chip for each and every of the 3 voltage domain names.
8V, DC-DC Result and boost 14V Voltage. Detection technique: 1) Do not plug IO line, plug just 12V: DC-DC output is around 9V, the boost output voltage is around 14V. Examination points should have LCK= 0. 9V, RI =1. 8V voltage, other examination voltages is 0; 2) Plug in IO, when you do not push the test secret, DC-DC No voltage outcome with boost, after pushing the test secret, image start working, right now DC-DC outcome image, photo device examination program establishes the voltage, rises with the functioning voltage.
At this factor the regular voltage of each test point should click here be: CLK: 0. 8 V, examination tool sends job, Carbon monoxide Because it's unfavorable. The DC degree will be drawn reduced, Immediate voltage is 1.
