A Secret Weapon For antminer 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 reduced degree; no low degree; no reduced level; no IO line It is 0V throughout standby, and is a pulse signal of regarding 0. 3 at the time of computation.
> Red line is the flow instructions of RST signal, signal circulation direction, signal circulation direction, from IO port 15 foot, after that from, then from, after that from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V during standby, and also 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 calculating. 2. 2 Number 3 shows the crucial circuits on the front of the S9 hash board. figure 2. inter-chip test factors 1) examination points in between each chip (After focusing the image listed below): number 2 During maintenance, the examination factor in between the test chip is the most straight the mistake place setting of the connection.
S9 Secret circuits on the front of the Procedure board Note that: Because the version of the S9 hash board is not precisely the exact same, the LDO-1. 8V power supply of the very early voltage domain names is powered get more info by a different outer LOD power supply chip for each and every of the three voltage domains.
Test factors have to have LCK= 0. 8V voltage, other examination voltages is 0; 2) Plug in IO, when you do not press the examination secret, DC-DC No voltage output with boost, after pushing the test secret, Image begin working, at this time DC-DC result Photo, PIC device examination program sets the voltage, increases with the functioning voltage.
With the outcome of the system function, return after operation NONC. At this moment the regular voltage of each test point should be: CLK: 0. 9 in CO:1. 6-1. 8 V, examination device sends out work, CO Since it's adverse. So the DC level will be pulled low, Rapid voltage is 1.
