The smart Trick of asic miner repair That Nobody is Discussing

3 Around the pulse signal. Purple is B (BI, BO) signal flow,) signal flow, from 00 chip to chip to 62 reduced degree; no low degree; no reduced level; no reduced level; no IO line It is 0V during standby, and also is a pulse signal of regarding 0. 3 at the time of estimation.

> Red line is the flow instructions of RST signal, signal circulation direction, signal flow direction, 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 is determined 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 Number 3 reveals the essential circuits on the front of the S9 hash board.

S9 Secret circuits on the front of the Procedure board Note that: Because the variation of the S9 hash board is not exactly the same, the LDO-1. 8V power supply of the very early voltage domain names is powered by a different outer LOD power supply chip for each of the three voltage domains.

8V, DC-DC Output as well as boost 14V Voltage. Detection technique: 1) Do not plug IO line, plug only 12V: DC-DC output is around 9V, the boost result voltage is around 14V. Examination factors have to have LCK= 0. 9V, RI =1. 8V voltage, various other examination voltages is 0; 2) Plug in IO, when you do not press the test key, DC-DC No voltage result with increase, after pressing the test official site key, PIC beginning functioning, currently DC-DC output PIC, PIC device test program establishes the voltage, climbs with the working voltage.

At this factor the regular voltage of each test point must be: CLK: 0. 8 V, examination tool sends work, CO Due to the fact that it's negative. The DC level will be pulled low, Immediate voltage is 1.
