Master core repair skills and become a certified Antminer T21 hash board repair expert.

Is your Antminer T21 facing high hashboard failure rates, rising repair costs, and unreliable third-party repair services? A downtime means lost profits!

ZEUS MINING, an industry-leading ASIC miner technical service provider, has officially launched a systematic online Antminer T21 hashboard repair training course. This course provides in-depth coverage of circuit principles, workflows, and common fault points. From the symptoms to the root causes, help you to quickly and accurately identify problems, including power failure, hash failure, low hashrate, and chip damage. High-definition videos demonstrate key hands-on procedures such as component inspection and replacement (such as chips, capacitors, and resistors), and PCB repair. Learn how to properly use air guns, soldering irons, and testing instruments.

We aim to condense years of maintenance experience  a set of replicable and easy-to-master professional skills, empowering you to transform from a "user" to a "repair expert", enabling you to perform in-house repairs within your mining farm, significantly shortening the downtime of faulty miners, reducing external repair costs and spare parts procurement costs, and directly improving your mining profitability.
