antminer hashboard repair Secrets

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

> Red line is the circulation instructions of RST signal, signal circulation instructions, signal flow instructions, 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, as well as 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 computing. 2. 2 Number 3 shows the key circuits on the front of the S9 hash board. number 2. inter-chip test factors 1) examination points between each chip (After focusing the picture below): figure 2 Throughout maintenance, the examination point in between the test chip is the most straight the mistake place setting of the connection.

S9 Trick circuits on the front of the Procedure board Note that: Since the variation of the S9 hash board is not specifically 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 3 voltage domain names.

Test points must have LCK= 0. 8V voltage, various other examination voltages is 0; 2) Plug in IO, when you do not press the test secret, DC-DC No voltage outcome with increase, after pushing the examination key, Photo click here beginning working, at this time DC-DC outcome Photo, Photo device test program establishes the voltage, rises with the working voltage.

At this factor the typical voltage of each test point should be: CLK: 0. 8 V, examination device sends work, Carbon monoxide Since it's unfavorable. The DC level will be pulled reduced, Immediate voltage is 1.
