Axis control units
Drive frequency converters
Position sensor feedback boards
Drive power modules
Numerical control controllers
Repair examples
Typical cases from our practice, without naming a specific customer.
Line stalled by an axis control failure
Problem: A CNC machine stopped mid-shift - its axis control unit had failed, and the line could not keep running without it.
Solution: BoardMaster diagnostics pinpointed the faulty component in a single visit, and the unit was restored and returned to production without a multi-week wait for a new board.
False position sensor readings
Problem: A machine started giving inaccurate position readings - the cause was a feedback board damaged by a voltage spike.
Solution: We restored the damaged part of the board and verified reading accuracy on a test bench after the repair.
Counterfeit component in a frequency drive
Problem: A drive frequency converter kept failing after a repair at a third-party shop - diagnostics found a counterfeit component installed during the earlier repair.
Solution: We replaced the counterfeit part with a genuine component and ran a full diagnostic on the unit, removing the cause of the repeat failures.
How the repair works
From intake to return to service, in six clear steps.
Equipment intake
We receive the equipment at the workshop or arrange transportation from anywhere in Russia.
BoardMaster diagnostics
We pinpoint the fault at the component level on certified BoardMaster equipment.
Approval
We confirm the cost and timeline and start work once you approve it.
Repair and soldering
We restore the damaged part: soldering, BGA/SMD reballing, component replacement.
Testing
We test the repaired unit under load and confirm it works.
Handover
We hand over the finished equipment or arrange return shipping.
Why repair, not replacement
Less production line downtime
BoardMaster diagnostics finds the fault quickly instead of leaving the machine idle for weeks.
Repair for models more than a few years old
We restore boards for which the supplier no longer has a direct replacement in stock.
Counterfeit component protection
We check the component base for authenticity - a common cause of repeat failures after repairs at non-specialized shops.
Cheaper than a new board
Repairing the specific faulty component costs a fraction of a new assembled board.
