④ Detect whether or not the pins of the primary chip aren't soldered correctly (there are tins around the pins from the facet during the repair approach, but right after taking away the chip, it really is located which the pins are not stained with tin);
If there is Bogus welding, it really should be re-soldered. If there is injury, it needs to be measured whether or not the resistance value is normal. Exchange the corresponding parts abnormally, and Look at the little board soldered over the PCB; the small board is proven inside the figure underneath.
Once the defective chip is located, weld the chip once again by incorporating flux throughout the chip and heating the solder joints of the chip pins to the dissolved condition. This tends to prompt the chip pins and pads to re-run in and gather the tin, attaining the result of tinning once again.
● Following the regimen check is handed (the shorter-circuit exam of the general regime examination is essential to stay away from the chip or other materials staying burnt due to the shorter circuit when the facility is turned on), the chip test might be executed Together with the hashboard tester, and the positioning is usually determined according to the check result of the hashboard tester.
2. When using the S19 Professional+ Hyd sequence exam fixture for the first time, utilize the SD card flash software to update the FPGA on the fixture Regulate board, unzip it and copy it towards the SD card, and insert the cardboard into your fixture card slot.
Pattern NG is due to the large distinction between the features with the chip together with other chips. At present, it is observed which the chip die is destroyed, so just substitute the chip. Based on the log facts, the substitute procedures are as follows:
4. Make the SD card In accordance with the necessities, double-sided warmth sink, 8 periods Parrer check, you might want to make the SD card as demonstrated within the determine down below:
Does any info on this site appears incorrect and you would like for us to examine it? Describe The difficulty with just as much data as you possibly can.
b) If one chip are available in move a), it implies that the very first chip and also the earlier circuit are superior. Use a similar method to check the following chips. For instance, quick-circuit the 1V8 exam position as well as RO take a look at place among the 38th and 39th chips. In case the log can find 38 chips, the 1st 38 chips haven't any challenge; if you still discover 0 chips, Verify the 1V8 first; if It is really regular, this means that there is a dilemma With all the chip just after 38.
If you have any dissatisfaction in the course of the transaction or have important recommendations for us, remember to Make contact with us by using this email deal with:
① For starters, visually inspect the hash board to find out if there is any deformation or burning on the PCB. If there is any phenomenon, it need to be dealt with initial.
Be part of the global Neighborhood of miners who rely on minerstat to elevate their mining match. Do you think you're prepared to unlock your mining potential?
I was let down with the overall performance of the hash board. It was slower than other choices I had tried, and failed to provide exactly the same volume of hashing electric power.
a. Make sure the fan Price Here connector is plugged into the socket and there is no problems on the enthusiast cable. (Beneath images are undesirable socket and poor cable illustrations)
