seven. Immediately after repairing the hash board, the thermal gel over the drinking water cooling board have to be eradicated and reprinted.
Repair system: Examine the looks, measure the chip capacitor or resistance in front, typically It truly is caused by poor chip soldering or a chip capacitor, resistor detrimental or irregular resistance; VI. Handle Board Issue Creating the Following Issues 1. The whole miner does not do the job one) Check out if the voltages at numerous voltage output points are typical. U8 can be disconnected first if 3.3V is short-circuited. If it remains brief-circuited, the CPU is usually unplugged for measurement. For other voltage abnormalities, normally change the corresponding converter IC. two) If your voltage is regular, you should Check out the welding status of the DDR/CPU. three) Try to update the flash system with SD card; Should the miner of which the Handle board is reflashed should commence normally, the next two methods are needed: a) After the card Restoration is passed, the inexperienced LED indicator will be generally on, and the facility shall be restarted; b) Watch for 30s just after powering on all over again (some time class of turning on OTP).
(1) Once the integer is claimed, it's important to examine if the Level change small board is welded properly, and to check if the elements about the little board have Wrong soldering.
3. Make the SD card As outlined by the necessities. In the event the hash board is only set up with just one-sided heat sink and detect the chip, immediately decompress the compressed offer for making the SD card;
one. Pay attention to your Procedure process when changing the chip. Soon after changing any extras, the PCB board shall have no noticeable deformation.
In the event numerous chips in the identical area Have got a lower reaction charge, the a person with the reduced nonce in that domain should really be replaced.
Examine the welding high quality of your chip which connects sensor along with the compact warmth sink. The deformation of huge heat sink product will induce very poor heat dissipation with the chip and have an impact on the temperature difference.
Open up MPLABIPE and select machine: PIC16F1704, click energy to choose the facility supply manner, then simply click operate. Step one: pick "file" to discover the .HEX file being programmed; the second phase: click on "hook up" to attach Commonly; the 3rd phase: simply click the "application" button, and immediately after completion, click "confirm" to prompt the verification to establish that the programming is productive.
b) If one chip can be found in step a), it indicates that the very first chip as well as past circuit are very good. Use an identical system to examine the following chips. By way of example, quick-circuit the 1V8 exam point along with the RO exam place between the 38th and 39th chips. In the event the log can find 38 chips, the main 38 chips haven't any problem; if you continue to uncover 0 chips, check the 1V8 very first; if It can be regular, this means that there's a dilemma While using the chip after 38.
a-4) Test if the pins of the Buy Here initial chip are soldered nicely (it was located through repair the pins are tinned observing from the side, but the pins usually are not stained with tin at all when the chip is eradicated)
a) Following the card recovery is handed, the inexperienced LED indicator is going to be constantly on, and the power shall be restarted;

Disclaimer: Please Be aware that this information reveals only minerstat supported capabilities and might vary within the features that the particular mining components gives.
Check with the voltage value assortment described with the signal development. If your calculated voltage price is just too substantial, it could be when compared Together with the calculated values of adjacent groups for judgment.
