b) If just one chip can be found in action a), it signifies that the main chip as well as previous circuit are ordinary. Use an identical process to check the next chips. One example is, Should the 1V2 examination place and RO examination point between the 38th and 39th chips are brief-circuited, In the event the log can find the 38th chip, then there is absolutely no difficulty with the first 38 chips. If 0 chips remain located, 1st Verify whether or not the 1V2 is standard.
Recently, quite a few companies professing for being mining firms imitate us and say that they're connected to us, or that they're our branch corporations, that has brought on customers for being deceived.
Check the welding excellent of the warmth-delicate chip and the little warmth sink. The deformation of the big warmth sink materials will cause poor warmth dissipation on the chip and affect the temperature big difference. Determine 5-fourteen 4. Phenomenon: One board detection chip is not really total (PT1/PT2 stations) a) Liquid crystal display Screen ASICNG: if (0), to start with measure the entire voltage of your measuring domain plus the Enhance circuit 19V is ordinary, and then make use of the shorter-circuit probe to small-circuit the RO exam stage as well as 1V8 check point in between the very first and the second chip, and then run the program to locate the chip. Looking at the serial port log, if 0 chip is still uncovered presently, it will be considered one of the following scenarios: a-1) Use a multimeter to evaluate if the voltages with the 1V8 and 0V8 take a look at points are one.8V or 0.8V. Otherwise, it suggests that the 1.8V or 0.8V LDO circuit of the area is abnormal, or The 2 ASIC chips of the domain is just not soldered nicely; most of the are caused by short circuits of 0.8V, one.8V patch filter capacitors (measure the resistance in the patch filter capacitors relevant to the front and back from the PCBA). a-two) Test if the circuits of U1 and U2 are abnormal, like resistance welding, and so forth.
Two hash boards need to be put simultaneously to variety an air duct when utilizing the chassis to dissipate heat. For one-sided tests in creation, the air duct should also be shaped.
In general, the S19PRO Hash Board is a sound choice for miners seeking successful and reliable hashing energy. It fits nicely and has labored perfectly to this point.
Against this, once you click a Microsoft-delivered advertisement that appears on DuckDuckGo, Microsoft Advertising does not associate your advertisement-simply click conduct by using a consumer profile. Additionally, it does not retail outlet or share that facts other than for accounting needs.
Examine the tools to make certain the test fixture can get the job done generally. Determine the parameters of the upkeep station test program, the Model from the check jig, as well as other relevant parameters.
eight. To exchange a completely new chip, printing pins and soldering paste are necessary to make certain the chip is pre-soldered and after that soldered to your PCBA for repair
We’re actively teaching added workers to get orders out a lot quicker and provide the support you are entitled to. Thank you for your endurance and comprehending as we expand to fulfill your needs.
4mm); when changing a completely new chip, you need to tin the chip pins after which solder on the hashboard, and afterwards lock substantial heat sinks immediately after making use of thermal gel evenly about the chip surface area.
d-1) The very first case: the exam time is essentially similar to the good board (generally the worth of X is not going to change each time you test) (check time refers back to the time from when the start take a look at button is pressed to the results of ASICNG: (X) shown on the LCD).
3. Following repairing, the hash board needs to be tested in excess of two times to get OK ahead of it may possibly pass! 4. Check out whether or not the resources and hash board testers can operate normally, determine the upkeep Look Here station to check computer software parameters, take a look at fixture variations, etcetera. five. During the take a look at of repairing and changing the chip, the chip ought to be analyzed initially, after which you can the perform examination shall be carried out right after passing. The operate check have to be sure that the smaller heat sink is welded competent. When installing the massive warmth sink, the surface area from the chip must be evenly coated with thermal gel as well as cooling lover shall be at comprehensive pace. When utilizing the chassis to dissipate heat, two hash boards really should be positioned concurrently to sort an air duct. 6. When measuring the sign, use 4 supporters as assistance for heat dissipation, as well as the fans shall keep entire velocity. 7. When powering over the hash board, the consumer must initially connect the detrimental copper wire of the power offer, then the optimistic copper wire of the ability source, and finally plug inside the sign cable. When eliminating, the get of installation has to be reversed. Initially, eliminate the sign cable, then eliminate the beneficial copper wire of the facility source, And eventually get rid of the detrimental copper wire of the facility source. When the user does not observe this get, it is vitally straightforward to cause damage to R8, R9, U1, U2 (not all chips can be found). Prior to testing the sample, the repaired hash board needs to be cooled down right before testing, otherwise, it may induce PNG tests. 8. To interchange a completely new chip, printing pins and soldering paste are demanded to make sure that the chip is pre-soldered and after that soldered to the PCBA for repair. III. hash board tester creating and issues needing consideration The supporting fixture in the hash board tester ought to fulfill the heat dissipation in the hash board and aid the measurement of signals. one. Use the 19 sequence hash board tester SD card swiping system for The 1st time to update the hash board tester Management board FPGA, unzip it and copy it to your SD card, after which insert the card into your hash board tester card slot; electricity on for about 1 minute and await the Command board indicator to double flash 3 instances, then the update is done; (if It's not necessarily current, it might lead to a specific chip to become undesirable in the check). Figure 3-1 2. Make the examination SD card In keeping with the requirements, and straight unzip the compressed package deal of The only-sided heat sink inspection chip to help make the SD card; Determine three-2 3. The check SD card will probably be created In line with the requirements, as well as the double-sided heat sink 8-occasions patter check must make an SD card, as shown in the figure under;
S19 specs, computing energy use, electricity supply, utilization surroundings together with other relevant details are revealed inside the tables:
