a-four) Verify Should the pins of the very first chip are usually not soldered nicely (it absolutely was found in repair which the pins are tinned observing in the side, nevertheless the pins are certainly not stained with tin whatsoever when the chip is taken out)
seven. When powering around the hash board, the adverse copper wire of the ability provide needs to be linked initially. Right before tests the sample, the repaired hash board has to be cooled down just before testing, or else it's going to result in examination PNG.
Solder paste column M705, flux, board washing drinking water with absolute Alcoholic beverages; board washing water is used to clean up the solder residue following repair; thermal gel (specification: Fujipoly SPG-30B) is used to smear the surface of the chip just after repair ; ball-planting metal mesh, solder absorption wire, solder ball (the ball diameter is suggested to be 0.
8V ranging from the first chip. Should the serial port stops long-expression operation following the brief circuit, the main chip is working thoroughly.
As for the issue which the control board can not start out (not networked), the user wants to exchange the U1 (principal Management IC FBGA of Command board). U1 can no longer be Utilized in 19 sequence soon after replacement
● After the plan exam is passed (the small-circuit take a look at of the general program test is essential to Inquire Now avoid the chip or other resources remaining burnt a result of the short circuit when the ability is turned on), the chip test could be done Together with the hashboard tester, and the positioning may be determined in accordance with the test result of the hashboard tester.
3. Should the PICsensorNG is shown over the Liquid crystal display display screen of your hashboard tester and the check study temperature is abnormal, then Stick to the ways below to troubleshoot:
Examine the welding high quality of the warmth-delicate chip along with the little heat sink. The deformation of the massive heat sink substance will lead to weak heat dissipation with the chip and impact the temperature distinction.
The supporting fixture of your hashboard tester really should satisfy the warmth dissipation on the hashboard and facilitate the measurement of alerts.
When using the chassis to dissipate heat, 2 hashboards needs to be put concurrently to variety an air duct. The one-sided take a look at from the manufacturing should also make sure that the air duct is fashioned (important).
2. Make the exam SD card In keeping with the requirements, and right unzip the compressed package of the single-sided heat sink inspection chip for making the SD card;
Be sure to be cautious never to imagine any impostors, remember to Look at our suitable Speak to info and Watch out for becoming deceived acquiring cheated, and dropping revenue. please Examine our correct Speak to way: Listed here
I have experienced no problems with this particular hash board due to the fact putting in it in my mining machines. It operates flawlessly and provides dependable performance.
a. Ensure the admirer connector has long been plugged in to the socket and there is no injury around the enthusiast cable. (Down below pics are negative socket and bad cable illustrations)
