two. Once the EEPROM NG is exhibited on the LCD display from the hashboard tester, Look at whether the welding of U5 is normal;
Investigating the serial port log, if 0 chips are still identified at the moment, It's going to be one among the subsequent conditions:
Right measure the area voltage to Find the problematic area, or make use of the 1V8 and RO shorter-circuit approach to Identify the irregular placement.
a) Liquid crystal display display ASICNG: if (0), initial evaluate the entire voltage in the measuring area and also the Strengthen circuit 20V is regular, and after that utilize the brief circuit probe to quick-circuit the RO test issue as well as the 1V8 check place in between the initial and the second chip, and after that function This system to locate the chip. Check out the serial port log, if 0 chip is still found presently, Will probably be among the next situations: a-one) Use a multimeter to evaluate whether the voltages within the 1V8 and 0V8 check points are 1.8V or 0.8V. If not, it suggests which the 1.8V or 0.8V LDO circuit of the domain is irregular, or The 2 ASIC chips of the area just isn't soldered very well; most disorders of this phenomenon are a result of quick circuits of 0.8V, 1.8V patch filter capacitors (measure the resistance of the patch filter capacitors connected with the front and back in the PCBA). a-2) Look at if the circuits of U2, U3 and U4 are abnormal, like resistance welding, and so forth. a-3) Measure the resistance of R232 or R233 using a multimeter to examine if it is in just one ohms as well as looking at will not likely leap randomly. If not, make sure you swap these two resistors. a-four) Verify If your pins of the first chip are soldered properly (it had been discovered throughout repair that the pins are tinned observing with the facet, even so the pins aren't stained with tin whatsoever when the chip is taken off). b) If a person chip can be found in action a), it suggests that the 1st chip as well as the prior circuit are very good. Use an identical process to examine the subsequent chips. For instance, brief-circuit the 1V8 exam issue and also the RO take a look at issue concerning the 38th and 39th chips. In the event the log can find 38 chips, the primary 38 chips don't have any issue; if you still uncover 0 chips, Verify the 1V8 very first; if It truly is normal, this means that there's a trouble with the chips after 38. Proceed to analyze with dichotomy until the problematic chip is discovered. Assuming that there is a issue With all the Nth chip, if the 1V8 and RO concerning the N-1th and Nth chips are small-circuited, N-one chips can be found, but when the 1V8 and RO between the Nth and N+1th chips are small circuited, the entire chip can't be discovered.
Less chain: Which means a few boards are lacking a person board. Generally, You will find a problem Using the link concerning the hash and Regulate boards. Check the cable to discover if there is an open up circuit.
● When finding the defective chip, the chip really should be welded once again. The tactic is to incorporate flux around the chip (ideally no-thoroughly clean flux), and heat the solder joints in the chip pins to a dissolved state to prompt the chip pins and pads to re-run in and acquire the tin, In order to obtain the influence of tinning all over again. In case the fault continues to be the identical immediately after re-soldering, you are able to specifically exchange the chip. ● The repaired hash board might be judged as a very good item with over two passes when tests Using the hash board tester. For The 1st time, following replacing the sections, await the hash board to chill down, utilize the hash board tester to test, and after the test is handed, established it apart and then amazing it down. For the 2nd time, after a couple of minutes when the hash board cools down, exam all over again. 0 About merchandise purchase, you should contact our sales manager:
3. If the PICsensorNG is displayed on the Liquid crystal display display of the hashboard tester plus the examination read temperature is irregular, then Adhere to the methods under to troubleshoot:
Our group of experts makes certain that each hashboard we promote satisfies our significant expectations of high-quality and performance. We have an understanding of the significance of reducing downtime in mining operations, Look Here Which’s why we attempt to deliver the most effective replacement hashboards on the market.
PatternNG is caused by the large difference between the attributes with the chip as well as other chips. At the moment, it's found the chip die is destroyed, so just substitute the chip. Based on the log facts, the substitution regulations are as follows:
(two) U1 cannot be made use of on other number of versions if the OTP perform is enabled within the control board.
d-1) The main scenario: the check time is largely similar to The great board (typically the value of X will never modify every time you check) (take a look at time refers to the time from when the start take a look at button is pressed to the results of ASICNG: (X) displayed over the LCD).
The tactic for repairing the issue is as follows: during the PT2 exam, carefully keep track of the serial port print log. In the event the serial port has long been functioning for an extended period of time, use a brief-circuit probe to brief-circuit RO and one.
d-1) The very first circumstance: the take a look at time is basically similar to the good board (normally the value of X will likely not transform each time you take a look at) (check time refers back to the time from when the beginning examination button is pressed to enough time when the result of ASICNG: (X) is exhibited on the Liquid crystal display).
Keep on to investigate with dichotomy until finally the problematic chip is discovered. Assuming that there's a difficulty Together with the Nth chip, when the 1V8 and RO concerning the N-1th and Nth chips are limited-circuited, N-one chips can be found, but when the 1V8 and RO in between the Nth and N+1th chips are shorter circuited, all the chip cannot be observed.
