④ Detect whether the pins of the main chip are not soldered appropriately (you can find tins over the pins from your side throughout the repair procedure, but right after removing the chip, it is actually located that the pins usually are not stained with tin);
seven. When powering about the hash board, the negative copper wire of the facility offer has to be related very first. Right before tests the pattern, the repaired hash board need to be cooled down before screening, in any other case it will bring about exam PNG.
The voltage of every voltage domain is about 0.32V. When there is 16V energy source, normally it's got area voltage. The priority is provided to measure the output of the facility supply terminal in the hashboard and check whether the MOS is brief-circuited (measure the resistance involving pins one, four and 8). If 16V has energy supply but no domain voltage, keep on to check.
Repair process: through the PT2 exam, Verify the serial port print log. When the serial port begins to function for your long time, use a brief-circuit probe to short-circuit RO&one.
If Sure, you must substitute the chip; if not, measure the resistance worth of the resistor close to it, and switch it if the resistance value is simply too substantial;
d-2) The 2nd situation; the take a look at time is sort of 2 times as long as the good board (occasionally the value of X will adjust each and every time you exam, and occasionally X=0); presently, the log ordinarily has the following facts (the purple amount will not be 13 sometime, dependant upon which seat the hashboard tester is connected to); in the exam, think which the area voltage of the many fields in Purchase Here front of the irregular situation is nearly lower than 0.
Join the global Local community of miners who trust minerstat to elevate their mining activity. Will you be prepared to unlock your mining opportunity?
eight. To interchange a different chip, printing pins and soldering paste are demanded to make certain that the chip is pre-soldered then soldered on the PCBA for repair
At that time, Microsoft Marketing will make use of your comprehensive IP address and person-agent string making sure that it may possibly thoroughly course of action the advert click and cost the advertiser.
In the event the chip isn't observed, check for attainable problems like irregular voltage in the 1V8 and 0V8 take a look at factors, issues Together with the U1 and U2 circuits, resistance of R8 or R9, and whether the pins of the main chip are soldered perfectly.
● When finding the defective chip, the chip ought to be welded again. The method is to incorporate flux throughout the chip (preferably no-thoroughly clean flux), and heat the solder joints in the chip pins into a dissolved state to prompt the chip pins and pads to re-operate in and collect the tin, In order to achieve the effect of tinning again. In the event the fault remains the identical just after re-soldering, you can straight change the chip.
By bringing their unique gear, individuals can figure out how to correct up to 5 damaged gadgets during Each and every session, building the vacation buy alone. Don’t let technological particulars hold you back.
Repair process: Check out the appearance, measure the chip capacitor or resistor in entrance, it is generally brought on by weak soldering on the chip or even a destroyed chip capacitor or resistor or irregular resistance worth;
Continue on to investigate with dichotomy until the problematic chip is found. Assuming that there's a issue with the Nth chip, once the 1V8 and RO between the N-1th and Nth chips are small-circuited, N-one chips are available, but when the 1V8 and RO amongst the Nth and N+1th chips are short circuited, all the chip can not be identified.
