What should I do if my hashboard is damaged?
Investigate hashboard for obvious failures (burns, swollen chips, etc) and set board aside if found. Blow excess dust from hashboard with Data-Vac. Spray alcohol between hashboard heatsinks, allow alcohol run-off into a bin for later disposal.
What tools do you use to test the hash board?
Skilled mastery. 2. The hot air cylinder is used for chip disassembly and soldering. Be careful not to heat it for a long time to avoid PCB foaming. 3. DC stabilized power supply (output 12V, 20A), used for the test and measurement of the hash board. 4. Fluke 15b+ multimeter, tweezers, Debug, G7 maintenance special control board, oscilloscope . 5.
How do I know if my Hash board is good quality?
• The repaired hash board can be determined to be a good product if it passes the fixture tests for more than twice.
What does it mean when the hash board does not run?
5. Not running: No running means that the test box cannot detect the chip information of the hash board, but displays NO hash board; this phenomenon is the most common and the fault range involved is also wide.

Why do you need to be familiar with chip soldering?
2. You must be familiar with chip soldering to avoid blistering and deformation of the PCB or damage to the pins.
How to tell if a signal chain is broken?
For example, a chip itself can work, but it will not forward other chip information; at this time, the entire signal chain will come to an abrupt end, and lose a large part of it, which is called broken chain. Generally the broken chain can be displayed by the test box. For example, when the test box detects the chips, only 14 chips are detected. If the number of preset chips is not detected in the test box, it will not run, so it will only display how many chips are detected, at this time, according to the displayed number "14", the problem can be found by detecting the voltage and impedance of each test point before and after the 14th chip.
How many crystal oscillators are in the T1558?
2. The T1558 clock is two 12M crystal oscillators, which are transmitted in series from the first chip to the 30th, and 31 to the last chip.
What does the black number on a chip mean?
2. The black numbers represent the order and bit number of the chip.
Can you use debug connection for chip detection?
2. After the routine detection is no problem (generally, the short‑circuit detection of the routine detection is necessary, so as not to burn the chip or other materials due to the short circuit when the power is turned on), you can Use DEBUG connection for chip detection, and judge and locate according to the detection result.
How to clean hashboards with alcohol?
