three) Seek to update the flash method with SD card;If your Handle board card Restoration equipment should start off Usually, the next two measures are necessary:
Very poor chip soldering or damage to the chip capacitor or resistor, or irregular resistance usually brings about The difficulty.
1. Utilize the 19 sequence hashboard tester SD card swiping method for The very first time to update the hashboard tester control board FPGA, unzip it and copy it to the SD card, after which you can insert the card in to the hashboard tester card slot; electrical power on for approximately 1 moment and watch for the Management board indicator to double flash 3 instances, then the update is concluded; (if It's not current, it could bring about a certain chip for being lousy throughout the take a look at)
a) LCD Display screen ASICNG: if (0), initial evaluate the entire voltage in the measuring domain plus the Enhance circuit 20V is ordinary, and then utilize the quick circuit probe to brief-circuit the RO examination position along with the 1V8 exam level concerning the main and the 2nd chip, then function This system to find the chip. Verify the serial port log, if 0 chip is still identified presently, Will probably be amongst the next situations: a-one) Utilize a multimeter to measure whether or not the voltages in the 1V8 and 0V8 test factors are one.8V or 0.8V. If not, it implies that the 1.8V or 0.8V LDO circuit of the area is abnormal, or The 2 ASIC chips of this area will not be soldered perfectly; most disorders of this phenomenon are brought on by short circuits of 0.8V, 1.8V patch filter capacitors (evaluate the resistance with the patch filter capacitors associated with the back and front in the PCBA). a-2) Look at whether the circuits of U2, U3 and U4 are irregular, for example resistance welding, and many others. a-three) Evaluate the resistance of R232 or R233 by using a multimeter to examine whether it is in 1 ohms as well as the reading will never bounce randomly. If not, make sure you switch both of these resistors. a-four) Verify If your pins of the very first chip are soldered properly (it had been located all through repair which the pins are tinned observing from your side, however the pins will not be stained with tin in the slightest degree if the chip is removed). b) If 1 chip are available in stage a), it suggests that the main chip plus the prior circuit are very good. Use a similar system to check the next chips. As an example, quick-circuit the 1V8 take a look at place as well as the RO check stage in between the 38th and 39th chips. In case the log can discover 38 chips, the first 38 chips don't have any challenge; if you continue to come across 0 chips, Look at the 1V8 first; if it's normal, it means that there's a dilemma With all the chips immediately after 38. Continue on to research with dichotomy until finally the problematic chip is uncovered. Assuming that there's a difficulty with the Nth chip, in the event the 1V8 and RO involving the N-1th and Nth chips are short-circuited, N-1 chips are available, but if the 1V8 and RO among the Nth and N+1th chips are short circuited, the entire chip cannot be identified.
To the LCD Show ASIC75, small-circuit the 1V8 exam position and the RO exam level involving the 38th and 39th chips. If limited-circuiting forty seven chips, however the log reviews forty six, it signifies that the 47th chip can't be detected, as well as 47th chip ought to get replaced.
B) Look at if the 4 temperature sensors of U5，R216、R219、R220，U7，R221~R223，U8，R224~R226，U9，R229~R231 as well as matching resistance welding are abnormal, The situation with the temperature feeling is as proven in Determine 4-4 and five-13, the temperature sensor is all Situated within the back of the PCB, the resistance is found on the back and front with the PCB, and whether or not the temperature sensor three.3V electricity provide is standard;
As well as the cooling admirer is at entire speed. To utilize the chassis for warmth dissipation, two hash boards should be placed concurrently to sort an air duct. The one-sided take a look at of generation need to also ensure the development of an air duct (vital).
Repair method: Using the dichotomy technique, short-circuit the 1V8 take a look at position plus the RO test position concerning the 38th and 39th chips with the quick circuit probe. If the log can find 38 chips, there is not any issue with the main 38 chips; if short-circuiting the 47th chip, but the log reviews forty sixth, it implies which the 47th chip can't be detected, and there is no challenge Along with the Visible inspection. Generally, the 47th chip shall be replaced;
PatternNG is caused by the big difference between the properties of your chip and also other chips. At this time, it is found the chip die is harmed, so just replace the chip. In accordance with the log details, the alternative procedures are as follows:
In the event the chip is not located, check for achievable issues like abnormal voltage with the 1V8 and 0V8 take a look at points, challenges Together with the U1 and U2 circuits, resistance of R8 or R9, and if the pins of the primary chip are soldered properly.
① First of all, visually inspect the hash board to find out when there is any deformation or burning in the PCB. If there is any phenomenon, it have to be handled initially.
three. Right after repairing, the hash board needs to be analyzed over two periods to become Alright ahead of it might go! four. Verify whether the equipment and hash board testers can function Commonly, determine the upkeep station to test software package parameters, test fixture variations, and many others. five. From the exam of repairing and changing the chip, the chip has to be tested initial, after which the operate check shall be done immediately after passing. The purpose take a look at have to be certain that the small warmth sink is welded skilled. When installing the massive heat sink, the floor on the chip has to be evenly coated with thermal gel and also the cooling fan shall be at whole pace. When using the chassis to dissipate heat, two hash boards must be put concurrently to sort an air duct. six. When measuring the signal, use 4 fans as assistance for heat dissipation, and the lovers shall preserve whole velocity. seven. When powering within the hash board, the consumer must 1st link the destructive copper wire of the power source, then the beneficial copper wire of the facility source, And eventually plug from the sign cable. When removing, the purchase of installation have to be reversed. Initial, clear away the sign cable, then take out the constructive copper wire of the facility supply, and finally get rid of the adverse copper wire of the power offer. If the person does not follow this get, it is rather straightforward to induce harm to R8, R9, U1, U2 (not all chips can be found). Prior to screening the pattern, the repaired hash board need to be cooled down in advance of screening, in any other case, it might bring about PNG screening. eight. To switch a completely new chip, printing pins and soldering paste are demanded in order that the chip is pre-soldered after Buy Now which you can soldered to your PCBA for repair. III. hash board tester producing and issues needing focus The supporting fixture of the hash board tester should really satisfy the warmth dissipation with the hash board and facilitate the measurement of indicators. one. Use the 19 sequence hash board tester SD card swiping program for the first time to update the hash board tester Management board FPGA, unzip it and replica it on the SD card, and then insert the card in to the hash board tester card slot; electric power on for about 1 moment and look ahead to the Management board indicator to double flash three moments, then the update is completed; (if It is far from updated, it may result in a particular chip to generally be poor in the course of the examination). Determine 3-1 2. Make the test SD card As outlined by the necessities, and instantly unzip the compressed package of The one-sided heat sink inspection chip to create the SD card; Figure 3-2 3. The check SD card is going to be produced In accordance with the requirements, as well as double-sided warmth sink 8-occasions patter test needs to make an SD card, as revealed during the figure beneath;
I had been dissatisfied Using the effectiveness of this hash board. It was slower than other choices I had tried, and failed to deliver precisely the same amount of hashing energy.
Consult with the voltage worth selection described by the sign development. If the calculated voltage price is just too massive, it could be compared Using the measured values of adjacent teams for judgment.
