Oscilloscope. The advised model is UTD2102CEX+. A network cable is required for an Connection to the internet along with a steady network.
7. When powering to the hash board, the damaging copper wire of the ability provide need to be linked initially. Before tests the sample, the repaired hash board has to be cooled down before tests, usually it will eventually induce test PNG.
Phase three: Simply click the “software” button. Soon after completion, simply click “verify”. It's going to prompt which the verification is concluded to confirm which the burning is productive.
Two hash boards must be positioned simultaneously to sort an air duct when utilizing the chassis to dissipate warmth. For single-sided tests in output, the air duct have to also be fashioned.
In case the chip’s look just isn't weakened, the chip with the bottom response fee in Every area ought to get replaced.
five. When repairing and changing the chip, you should exam the chip very first, after which do the purposeful test following passing. The useful exam have to make sure that the water-cooling plate is assembled appropriately.
● After the regimen examination is passed (the brief-circuit exam of the overall program exam is important to stay away from the chip or other components staying burnt mainly because of the shorter circuit when the ability is turned on), the chip check may be carried out Together with the hash board tester, along with the positioning may be determined in accordance with the check result of the hash board tester. ● According to the exhibited outcomes in the hash board tester detection, ranging from in close proximity to faulty chip, Test the chip exam details (CO/NRST/RO/XIN/BI) and voltages for example VDD0V8 and VDD1V8. ● In accordance with the sign movement, except for the RX sign is reversely transmitted signal (from No. 114 to No. one chip), quite a few of your indicators like CLK CO BO RST are forward transmission (one-114), along with the irregular fault position are available in the ability offer sequence.
8. To exchange a fresh chip, printing pins and soldering paste are expected in order that the chip is pre-soldered and then soldered into the PCBA for repair
Does any information on this webpage looks incorrect and you desire to for us to examine it? Describe The problem with just as much information as possible.
7. When powering within the hashboard, consumer have to to start with join the destructive copper wire of the facility source, then the positive copper wire of the facility offer, And at last plug inside the signal cable. When removing, the buy of installation has to be reversed. Very first eliminate the sign cable, then take out the favourable copper wire of the ability source, And eventually get rid of the unfavorable copper wire of the facility source.
① First off, visually inspect the hash board to determine when there is any deformation or burning of your PCB. When there is any phenomenon, it need to be addressed initially.
three. The test SD card is going to be produced In line with the requirements, plus the double-sided heat sink Go Here 8-periods Patter exam needs to make an SD card, as revealed in the figure beneath;
c) Liquid crystal display Show ASIC75: (Reporting 75), it ensures that the hash board can detect seventy six chips at 115200 baud charge, but only 75 chips are uncovered at 12M baud level, and one chip couldn't discover at 12M baud rate; Repair process: Using the dichotomy approach, brief-circuit the 1V8 exam position along with the RO check level in between the 38th and 39th chips in the quick-circuit probe.
Seek advice from the voltage worth variety explained with the sign pattern. In the event the measurement encounters a sizable deviation of the voltage price, it can be when compared With all the calculated value of the adjacent group to determine.
