4mm); when replacing a brand new chip, you'll want to tin the chip pins and afterwards solder towards the hashboard, and after that lock significant warmth sinks following implementing thermal gel evenly on the chip area.
Open MPLABIPE and select gadget: PIC16F1704, simply click power to pick out the power supply mode, then simply click function. The first step: pick file to find the .HEX file to be programmed; The next action: simply click connect to hook up Typically; The third move: click This system button, and just after completion, click on verifiy to prompt the verification to establish the programming is effective. Figure five-seven Determine five-eight Forth phase: Look at the boost circuit output
c) Liquid crystal display Display screen ASIC113: (Reporting 113), it ensures that the hash board can detect 114 chips at 115200 baud fee, but only 113 chips are located at 12M baud level, and just one chip couldn't be discovered at 12M baud fee; Repair process: Using the dichotomy process, short-circuit the 1V8 exam issue and the RO test stage concerning the 38th and 39th chips Along with the shorter circuit probe. If the log can discover 38 chips, there is absolutely no dilemma with the 1st 38 chips; if quick-circuiting the 47th chip, but the log reports 46th, it indicates that the 47th chip can not be detected, and there is no trouble with the visual inspection. Normally, the 47th chip shall get replaced; Determine five-15 d) Liquid crystal display Show ASICNG: (X, a specific chip is fixedly reported), There are 2 conditions: d-one) The first circumstance: the take a look at time is largely the same as The great board (normally the worth of X won't alter every time you exam) (check time refers back to the time from when the start take a look at button is pressed to enough time when the result of ASICNG: (X) is shown on the LCD). This example is likely being because of the irregular resistance welding of the entrance and rear CLK, CI, and BO with the Xth chip, so people shall deal with these 6 resistors. The modest likelihood is because of X-1, X, X+1, that's, among the a few chips, the next pins abnormal welding disorders of the chip happen: Determine 5-sixteen d-two) The next circumstance: the take a look at time is sort of twice as long as The nice board (in some cases the worth of X will transform whenever you take a look at, and in some cases X=0); at this time, the log usually has the next information (the pink amount is not really 13 someday, determined by which seat the hash board tester is linked to); over the examination, believe that the domain voltage of many of the fields in front of the irregular placement is nearly a lot less than 0.3V, along with the domain voltage of the back again fields are Pretty much all larger than 0.34V. This case is because of the chip not staying soldered perfectly, typically one.8V, 0.8V, RXT, CLK usually are not soldered well. It is usually recommended to straight measure the area voltage to locate which domain is the situation. The 1V8 and RO short-circuit technique Utilized in portion a) may Track down the irregular posture;
● Following the regimen test is handed (the shorter-circuit exam of the overall program take a look at is important to steer clear of the chip or other supplies becoming burnt due to brief circuit when the facility is turned on), the chip examination can be performed Using Antminer s19 Hashboard the hashboard tester, plus the positioning is often determined according to the check results of the hashboard tester.
The voltage of every voltage domain is about one.35V. When there is a 14V powering, there is generally a site voltage, as well as output of the facility terminal with the hash board is measured 1st; if there is a 14V powering but no domain voltage, proceed to check down.
Or The 2 ASIC chips in this domain are usually not soldered adequately. A lot of them are a result of shorter circuit of 0.8V and one.2V patch filter capacitors (evaluate the resistance from the patch filter capacitors related to the front and back sides on the PCBA).
Kernel Log: it retains records of ANTMINER's Procedure levels, which serves as a means to troubleshoot some popular troubles. The method to enter the miner log: enter the miner IP tackle within the deal with bar of Google or Firefox browser >> enter the user title/password (default root/root) >> the miner log
The repaired hash board could be judged as a very good solution with over two passes when tested While using the hash board tester.
b) If 1 chip can be found in stage a), it suggests that the 1st chip as well as the preceding circuit are superior. Use an identical strategy to check the subsequent chips. Such as, short-circuit the 1V8 test position and the RO take a look at stage among the 38th and 39th chips. When the log can find 38 chips, the initial 38 chips have no dilemma; if you continue to obtain 0 chips, Test the 1V8 initially; if It can be regular, it means that there is a challenge Along with the chip after 38.
(2) Secondly, if there's no trouble right after visual inspection, you may initial check the impedance of each voltage area to detect irrespective of whether There's a limited circuit or open up circuit. If found, it have to be dealt with initially.
d-one) The primary circumstance: the test time is largely the same as The nice board (commonly the worth of X will never adjust every time you examination) (exam time refers to the time from when the beginning check button is pressed to the results of ASICNG: (X) shown within the Liquid crystal display).

six. Determine the maintenance station item along with the corresponding check program parameters and test fixtures.
