PatternNG is a dilemma that occurs due to considerable discrepancies within the attributes of a certain chip in comparison with other chips. To resolve this concern, it's been identified the chip’s die is destroyed and desires to be replaced.
If there is Fake welding, it ought to be re-soldered. When there is problems, it must be measured if the resistance price is standard. Substitute the corresponding factors abnormally, and Examine the small board soldered over the PCB; the tiny board is revealed inside the determine underneath.
Solder paste column M705, flux, board washing drinking water with complete Alcoholic beverages; board washing h2o is employed to clean up the solder residue just after repair; thermal gel (specification: Fujipoly SPG-30B) is accustomed to smear the surface area with the chip right after repair ; ball-planting metal mesh, solder absorption wire, solder ball (the ball diameter is recommended to be 0.
log-area voltage print command The particular functions are as follows: Open putty , enter the IP from the miner in dilemma and click on Open up Determine six-7 two. Enter the consumer title, password and examination command to examine the NONCE reaction standing as well as the standing of voltage area. In case the NONCE and domain voltage are irregular, user can carry out measurement and servicing depending on the printed irregular chip.
3V, as well as domain voltage of the back again fields are Nearly all higher than 0.38V. This case is caused by the chip not remaining soldered very well, generally one.8V, 0.8V, RXT, CLK aren't soldered very well. It is suggested to instantly evaluate the domain voltage to Track down which area is the condition. The 1V8 and RO limited-circuit method Employed in area a) may locate the abnormal place;
5. When repairing and replacing the chip, you must examination the chip 1st, and afterwards do the useful test after passing. The purposeful take a look at need to ensure that the h2o-cooling plate is assembled appropriately.
Our replacement hashboards are not merely refurbished, They're upgraded to make certain greater performance and reliability than the initial. Every single hashboard goes by way of a rigorous Restoration course of action which makes them additional responsible than new kinds straight with the manufacturer.
Open MPLABIPE and select device: PIC16F1704, simply click energy to pick the facility source method, then click on run. Step one: choose "file" to find the .HEX file to get programmed; the next step: click "connect" to attach Ordinarily; the 3rd stage: simply click the "software" button, and immediately after completion, click "verify" to prompt the verification to confirm that the programming is effective.
Go on to research with dichotomy until the problematic chip is observed. Assuming that there is a dilemma with the Nth chip, if the 1V8 and RO amongst the N-1th and Nth chips are quick-circuited, N-one chips are available, but when the 1V8 and RO involving the Nth and N+1th chips are small circuited, the entire chip cannot be identified.
a-four) Check In the event the pins of the primary chip are soldered well (it was observed all through repair which the pins are tinned observing with the facet, although the pins are usually not stained with tin in the slightest degree in the event the chip is taken off)
● When finding the faulty chip, the chip really should be welded once again. The tactic is to incorporate flux around the chip (ideally no-clean up flux), and warmth the solder joints on the chip pins to a dissolved condition to prompt the chip pins and pads to re-operate in and accumulate the tin, so as to realize the outcome of tinning once more. If your fault remains the exact same following re-soldering, it is possible to directly swap the chip. ● The repaired hash board can be judged as an excellent merchandise with greater than two passes when screening Along with the hash board tester. For The 1st time, just after replacing the sections, look ahead to the hash board to chill down, use the hash board tester to test, and after the test is handed, set it apart and afterwards interesting it down. For the next time, following a few minutes when the hash board cools down, exam yet again. 0 About solutions acquire, you should Speak to our product sales supervisor:
three. Soon after repairing, the hash board has to be analyzed greater than two situations to be Okay right before it can move! four. Examine whether or not the tools and hash board testers can perform Commonly, determine the upkeep station to check software parameters, check fixture versions, and so forth. 5. From the exam of repairing and changing the chip, the chip needs to be analyzed first, after which the purpose examination shall be carried out soon after passing. The operate examination ought to be sure that the smaller heat sink is welded certified. When installing the massive heat sink, the surface of your chip need to be evenly coated with thermal gel as well as cooling supporter shall be at entire speed. When utilizing the chassis to dissipate warmth, two hash boards must be placed simultaneously to type an air duct. six. When measuring the signal, use four enthusiasts as assistance for heat dissipation, and also the fans shall retain total pace. seven. When powering about the hash board, the user will have to 1st join the adverse copper wire of the facility Order Here provide, then the favourable copper wire of the power provide, And at last plug in the signal cable. When eradicating, the order of set up has to be reversed. To start with, remove the signal cable, then take away the favourable copper wire of the facility supply, And eventually remove the damaging copper wire of the ability provide. In case the consumer does not abide by this get, it is vitally straightforward to induce harm to R8, R9, U1, U2 (not all chips are available). Right before tests the pattern, the repaired hash board has to be cooled down just before tests, usually, it could lead to PNG testing. eight. To exchange a fresh chip, printing pins and soldering paste are needed to make certain that the chip is pre-soldered after which soldered towards the PCBA for repair. III. hash board tester producing and matters needing awareness The supporting fixture from the hash board tester ought to fulfill the warmth dissipation in the hash board and aid the measurement of signals. 1. Utilize the 19 sequence hash board tester SD card swiping plan for The 1st time to update the hash board tester Handle board FPGA, unzip it and replica it towards the SD card, after which you can insert the card into your hash board tester card slot; power on for approximately one moment and wait for the Management board indicator to double flash three occasions, then the update is accomplished; (if it is not up-to-date, it may well cause a certain chip to get lousy through the take a look at). Determine three-1 2. Make the take a look at SD card according to the requirements, and straight unzip the compressed package deal of the single-sided heat sink inspection chip for making the SD card; Determine 3-2 three. The exam SD card will likely be produced In accordance with the requirements, and also the double-sided warmth sink eight-periods patter take a look at ought to make an SD card, as demonstrated while in the determine down below;
3V powering on the temperature sensor is normal; Examine the chip linked to the temperature sensor. The fabric deformation of the large heat sink will induce inadequate heat dissipation of your chip and have an effect on the temperature change.
a) LCD Show ASICNG: if (0), very first measure the overall voltage of your measuring area along with the Improve circuit 19V is typical, after which use the limited-circuit probe to quick-circuit the RO check point and the 1V8 exam position among the primary and the second chip, after which you can run This system to discover the chip.
