The smart Trick of hashboard repair That No One is Discussing
3 Around the pulse signal. Purple is B (BI, BO) signal circulation,) signal circulation, from 00 chip to chip to 62 reduced degree; no reduced level; no reduced degree; no low degree; no IO line It is 0V throughout standby, and also is a pulse signal of concerning 0. 3 at the time of estimation.
> Red line is the circulation direction of RST signal, signal flow instructions, signal circulation instructions, from IO port 15 foot, then from, after that from, then from 00 chip to 62 chip transfer chip transmission chip transmission; no IO signal, standby It is 0V throughout standby, as well as is determined 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 determining. 2. 2 Figure 3 shows the key circuits on the front of the S9 hash board. number 2. inter-chip test points 1) examination points between each chip (After focusing the image listed below): number 2 During maintenance, the examination factor between the test chip is one of the most straight the fault place setting of the connection.
S9 Secret circuits on the front of the Procedure board Note that: Due to the fact that the version of the S9 hash board is not precisely the very same, the LDO-1. 8V power supply of the very early voltage domains is powered by a separate peripheral LOD power supply chip for every of the three voltage domain names.
Examination points must have LCK= 0. 8V voltage, various other test voltages is 0; 2) Plug in IO, when you do not push the examination trick, DC-DC No voltage outcome with boost, after pressing the examination secret, PIC beginning working, at this time DC-DC result Picture, Image tool examination program establishes the voltage, increases with the functioning voltage.
With the outcome of the system function, return after operation NONC. Now the normal voltage of each test factor should be: CLK: 0. 9 in official web site carbon monoxide:1. 6-1. 8 V, examination tool sends job, carbon monoxide Since it's adverse. The DC level will be pulled low, Immediate voltage is 1.
