one) Since the initially-technology h2o radiator simply cannot satisfy the heat dissipation requirements, a water pump should be extra in collection (or two drinking water radiators in collection) in the course of the transformation;
a) After the flashing is effective, the green LED indicator mild is always on, and afterwards the ability is turned off and restarted;
Solder paste column M705, flux, board washing drinking water with absolute Liquor; board washing water is made use of to scrub up the solder residue just after repair; thermal gel (specification: Fujipoly SPG-30B) is accustomed to smear the surface area of your chip immediately after repair ; ball-planting steel mesh, solder absorption wire, solder ball (the ball diameter is usually recommended being 0.
Servicing method: Examine the appearance and measure the capacitance or resistance from the front chip. Normally, it truly is caused by lousy chip welding or destruction and irregular resistance of a specific chip capacitor or resistor, or issues with the chip by itself;
Should the chip’s look isn't broken, the chip with the bottom reaction level in Each individual area really should be replaced.
minerstat is not just A further calculator - It can be a robust mining platform that supports your copyright journey. Strengthen your profits, save precious time, and improve effectiveness with our suite of premium options:
● Once the routine test is passed (the quick-circuit examination of the final plan exam is essential to steer clear of the chip or other resources staying burnt due to limited circuit when the ability is turned on), the chip take a look at can be executed Along with the hash board tester, and the positioning can be determined based on the test results of the hash board tester. ● In accordance with the exhibited effects in the hash board tester detection, ranging from close to faulty chip, Look at the chip check points (CO/NRST/RO/XIN/BI) and voltages for instance VDD0V8 and VDD1V8. ● According to the signal move, apart from the RX signal is reversely transmitted signal (from No. 114 to No. one chip), quite a few in the alerts which include CLK CO BO RST are ahead transmission (one-114), and also the abnormal fault place can be found through the electric power provide sequence.
2. After there isn't any issues in schedule tests (brief circuit detection in regimen testing is mostly important to stay clear of burning the chip or other elements as a result of limited circuit when electrical power is on), the test fixture may be used to detect the chip, along with the positioning may be determined dependant on the check fixture detection success.
① Following the card is swiped successfully, the environmentally friendly LED indicator is often on, and the facility is turned off and restarted presently;
Test the Liquid crystal display Show ASICNG by measuring the full voltage of the measuring domain and Raise circuit.
If the large warmth sink substance is deformed, it can result in poor warmth dissipation with the chip and affect the temperature change.
If there's no difficulty Together with the connection, you'll be able to carry out the PT2 test on The only board to examine whether the exam can move. If it might be handed, most probably the Handle board is defective. In the event the test fails, utilize the PT2 upkeep process to repair.
a-3) Measure the resistance of R8 or R9 with a multimeter to check if it is within just ten ohms along with the reading will never bounce randomly. Otherwise, be sure to switch these two resistors. a-4) Verify In case the pins of the main chip are certainly not soldered nicely Order Here (it was found in repair which the pins are tinned observing within the side, though the pins aren't stained with tin in any respect when the chip is removed). b) If 1 chip can be found in move a), it suggests that the primary chip along with the preceding circuit are great. Use an identical method to examine the subsequent chips. Such as, small-circuit the 1V8 check stage and the RO take a look at level between the 38th and 39th chips. If your log can find 38 chips, the main 38 chips have no challenge; if you still uncover 0 chips, Examine the 1V8 first; if It truly is typical, this means that there's a challenge Together with the chip following 38. Keep on to analyze with dichotomy till the problematic chip is located. Assuming that there is a trouble With all the Nth chip, if the 1V8 and RO concerning the N-1th and Nth chips are short-circuited, N-1 chips are available, but if the 1V8 and RO concerning the Nth and N+1th chips are short circuited, the whole chip cannot be observed.
In keeping with this technique, find the chip that also has the long-time period working failure just after a certain chip is brief-circuited. Commonly, it really is caused by a certain chip harmful, so just switch it; Figure five-twenty seven. Phenomenon: PT1 chip check is Okay, PT2 purpose exam constantly studies a specific chip NG;
