The Single Best Strategy To Use For antminer hashboard repair
3 Around the pulse signal. Purple is B (BI, BO) signal flow,) signal flow, from 00 chip to chip to 62 low level; no low level; no reduced degree; no reduced level; no IO line It is 0V during 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 instructions, signal circulation direction, from IO port 15 foot, then from, then from, then from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V during standby, and is determined 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 these ASIC hashboards
8V when determining. 2 Figure 3 reveals the essential circuits on the front of the S9 hash board.
S9 Trick circuits on the front of the Procedure board Note that: Because the version of the S9 hash board is not specifically the exact same, the LDO-1. 8V power supply of the very early voltage domains is powered by a different outer LOD power supply chip for each of the 3 voltage domains.
8V, DC-DC Result as well as increase 14V Voltage. Detection approach: 1) Do not connect IO line, plug only 12V: DC-DC result is around 9V, the increase outcome voltage is around 14V. Examination factors 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 key, DC-DC No voltage outcome with increase, after pressing the examination trick, picture beginning working, currently DC-DC output picture, picture device examination program establishes the voltage, climbs with the working voltage.
At this point the normal voltage of each examination point should be: CLK: 0. 8 V, test device sends out job, CO website Because it's negative. The DC level will certainly be drawn low, Immediate voltage is 1.
