PatternNG is a difficulty that happens on account of important dissimilarities during the qualities of a specific chip compared to other chips. To solve this concern, it's been discovered that the chip’s die is damaged and desires to be replaced.
Abnormal temperature: Frequently, the temperature is significant. The maximum PCB temperature established by our checking procedure simply cannot exceed ninety℃.
Examine the welding quality of the warmth-sensitive chip as well as smaller warmth sink. The deformation of the big warmth sink product will bring about bad warmth dissipation on the chip and impact the temperature distinction. Determine 5-fourteen four. Phenomenon: Solitary board detection chip just isn't full (PT1/PT2 stations) a) Liquid crystal display Display screen ASICNG: if (0), first measure the total voltage with the measuring area as well as the Increase circuit 19V is regular, and afterwards use the short-circuit probe to shorter-circuit the RO take a look at position as well as the 1V8 examination point involving the first and the next chip, and afterwards function This system to find the chip. Investigating the serial port log, if 0 chip is still uncovered at this time, it will be among the subsequent scenarios: a-1) Utilize a multimeter to measure whether the voltages within the 1V8 and 0V8 test points are 1.8V or 0.8V. Otherwise, it implies which the one.8V or 0.8V LDO circuit of the domain is abnormal, or The 2 ASIC chips of the domain is just not soldered well; most of the are caused by shorter circuits of 0.8V, one.8V patch filter capacitors (evaluate the resistance from the patch filter capacitors associated with the front and back on the PCBA). a-2) Look at if the circuits of U1 and U2 are irregular, such as resistance welding, and so forth.
8V starting from the initial chip. When the serial port stops long-expression Procedure once the small circuit, the main chip is working appropriately.
In general, the S19PRO Hash Board is really a good option for miners looking for effective and dependable hashing electricity. It suits well and it has labored very well so far.
● Following the regimen exam is handed (the limited-circuit test of the final regime test is necessary to steer clear of the chip or other components currently being burnt due to brief circuit when the power is turned on), the chip test is often carried out With all the hashboard tester, as well as the positioning might be determined based on the examination results of the hashboard tester.
And the cooling lover is at total pace. To use the chassis for warmth dissipation, two hash boards has to be placed at the same time to type an air duct. The single-sided take a look at of creation must also make sure the formation of an air duct (important).
2. Right after there are no complications in plan testing (small circuit detection in program testing is generally necessary to steer clear of burning the chip or other materials on account of limited circuit when electrical power is on), the examination fixture can be used to detect the chip, as well as positioning is usually determined based upon the take a look at fixture detection final results.
(two) Use the examination fixture from the V2.1010 Management board (its model is ZJ0001000001), the positive and damaging poles of the facility source from the check fixture should be installed using a discharge resistor, and it is suggested to work with a cement resistor of 25 ohms and earlier mentioned 100W.
Repair technique one: Evaluate whether the domain voltage of the reset very low chip area is lower than the conventional area, if it is reduced, measure whether Price Here or not the pin resistance in the reset very low chip is higher than that of the normal chip.
Pre-tin the chip pins with solder paste to exchange a whole new chip after which solder them into the PCB for repair.
Pattern NG is a result of the massive difference between the qualities of the chip and various chips. At the moment, it can be uncovered which the chip die is ruined, so just replace the chip. In accordance with the log info, the replacement principles are as follows: If the appearance from the chip is not damaged, just exchange the chip with the lowest reaction fee in Just about every domain.
It describes the troubleshooting of Bitmain Antminer S19 different faults, and describes the best way to use the exam applications for correct positioning.
Confer with the voltage worth variety explained via the signal development. In the event the measurement encounters a big deviation from the voltage benefit, it can be when compared Using the calculated value of the adjacent team to determine.
