④ Detect whether or not the pins of the initial chip are usually not soldered properly (you'll find tins within the pins through the side over the repair course of action, but just after removing the chip, it really is located that the pins are not stained with tin);
Lately, numerous corporations declaring to get mining providers imitate us and say that they are connected to us, or that they're our department providers, that has triggered clients to be deceived.
The voltage of every voltage area is about 0.32V. If there is 16V electric power source, normally it's got domain voltage. The priority is presented to evaluate the output of the ability source terminal on the hashboard and Check out whether or not the MOS is short-circuited (evaluate the resistance between pins 1, four and 8). If 16V has energy offer but no domain voltage, go on to examine.
(three) When changing the chip, it's important to plant tin over the pins with the chip initially, and afterwards solder it on the hash board. Utilize heat-conducting gel evenly about the surface area of the chip and after that put in the big heat sink.
③ Utilize a multimeter to measure the resistor of R8 or R9 to check out if it is within ten ohms, along with the examining won't soar randomly. If not, exchange equally resistors;
● Following the plan examination is passed (the short-circuit take a look at of the final regime check is important to avoid the chip or other materials currently being burnt due to quick circuit when the ability is turned on), the chip check is usually executed with the hashboard tester, as well as positioning can be determined in accordance with the check result of the hashboard tester.
The following fault illustrations are from Antminer 19 sequence mining devices, other Antminer types are for reference only.
Open up MPLABIPE and choose product: PIC16F1704, click on electricity to select the ability source method, then simply click run. The Purchase Here first step: choose "file" to locate the .HEX file to be programmed; the 2nd phase: simply click "hook up" to connect Usually; the 3rd phase: simply click the "program" button, and after completion, click on "confirm" to prompt the verification to confirm which the programming is productive.
We’re actively coaching additional team to have orders out more rapidly and provide the support you have earned. Thank you in your endurance and comprehending as we improve to meet your requirements.
(2) Secondly, if there is no issue immediately after visual inspection, it is possible to initially exam the impedance of each and every voltage area to detect whether or not There exists a limited circuit or open circuit. If discovered, it should be dealt with to start with.
● The repaired hashboard could be judged as a good products with more than two passes when testing Using the hashboard tester. For The 1st time, soon after changing the pieces, anticipate the computing board to chill down, make use of the hashboard tester to test, and after the examination is passed, set it aside and then awesome it down. For the second time, following a few minutes if the hashboard cools down, take a look at yet again.
Make sure you be careful never to believe any impostors, you should Check out our suitable Make contact with information and facts and Watch out for remaining deceived having cheated, and dropping funds. make sure you Examine our correct Make contact with way: Below
three. The SD tests card are going to be produced according to the necessities, as well as double-sided heat sink 8-situations Sample test has to make an SD card, as shown in the determine underneath;
Popular phenomena: IP can't be detected, chain detection is abnormal. If an abnormality happens in the course of the check, repairs should be performed according to the checking interface and check LOG prompts. The upkeep techniques for the whole miner initial take a look at and ageing test are the exact same.
